The method uses the binding relation object comprising the binding relation type and the binding relation value to represent the binding relation and manages the binding relation by setting an overall binding relation matrix, convenient for the operation of the binding implement and the form program run efficiency is increased.
Description
Technical field
The invention belongs to the data binding field, particularly relate to the related of data set and control, comprise maintenance, storage and the reduction of the binding method and the binding relationship of data set field element and control.
Background technology
Data binding is the mapping mechanism of setting up between data object and the control.Data binding is divided into static state and dynamic binding traditionally, also is divided into simple binding and complex-bound.Bind model in the static binding and fix, data binding is set up the back and is just no longer changed.Dynamic binding all possibly have the change of information at any time between model and the view, binding needs dynamic the maintenance.The simple binding is meant the monodrome mapping, and a control is tied to a data field element.Complex-bound is the mapping of one-to-many, many-one and multi-to-multi, and control can related a plurality of data set field element, the related a plurality of controls of data set field element, and a plurality of control and a plurality of field element is related.
Current, the data binding technology comprises two aspects:
The one, the foundation of binding relationship.The binding of model and control has manual binding method, is tied to the attribute of control to the attribute of model through function, and control property is set to model attributes; The naming rule method is also arranged, the code designation mapping ruler, such as method for reflection with configuration file etc. is set.
The 2nd, the foundation of informing mechanism.After the model change, the change of notice control property; Control property changes, and notification model changes.In model, adopt event registration mechanism, attribute makes an announcement to registered events after changing, and is triggered the change of view by registered events; View changes through the incident that triggers, and settings is in model.
The problem that the present invention relates to is the binding of data set and control in the list system.Data set is a kind of data structure, is to the description of the object that is generated after the data source structure operation (operations such as inquiry, renewal and modification), comprises the result field and the variable field subobject that generate after structuring action statement and the parse operation.After data set and control binding,, data source data is displayed through control through browsing the data source data that list can obtain the data set field of binding.Such as database sql statement select name, addressfrom information is through comprising statement, name and address attribute and type information thereof after the object data setization.Bind name field and control text name attribute, the user just can obtain information table name field value in the database data source through browsing list.Data set can be regarded virtual data acquisition as, and the binding of data set and control does not relate to the physical data operation, and binding information indicates the position that control obtains the data that will be provided with or show.
Complicated list design, the bindings of data set field element and control very frequently.The binding method of data set field element and control is that data set field element and control property are bound respectively at present; Its binding relationship is single; Each data set field element and control model element all will be set up binding relationship, and binding relationship is stored in the control model.For example a data set field element and control are bound the binding relationship object that the back is generated, just be stored in the control model.The major defect of this method is:
(1) binding relationship is dumb.Each control model element all will be set up binding relationship with each data set field element.Such as a composite control Table model, every row of the inside all must be set up binding relationship with data set element.The amount of the number of operations of designing form is just very big like this.If a Table has 10 row, must carry out bindings 10 times.
(2) after binding relationship is set up, be stored in the control model, binding relationship and data sets direct related information.When the data set field element changes, need cancellation and change the relevant binding relationship of element.Because binding relationship is present in the control model; The cancellation binding relationship must be searched for the control of whole list; Check whether each control has and the relevant binding relationship of variation element; If composite control must be searched for the binding relationship of composite control child control, cancel if just have.When wanting the deleted data collection, also to cancel all binding relationships related with this data set.If list is complicated, the control number that comprises is a lot, and the variation of each data set all will be carried out exhaustive search to control, consumes the plenty of time.Comprise 100 controls such as a list, the data set dimensions of variability have 5, once changes to carry out 500 search.In the list design, the variation of binding relationship is frequent between data set field element and the control, will consume a large amount of search times like this.For the server of handling mass data, the slow problem of its executing efficiency will highlight especially, can not satisfy the needs of effectively handling mass data at present fast.
To the problem that exists in the present complicated list system design; The present invention proposes a kind of new data binding way; Realize the dynamic binding of data source and control by this method, effectively solved long problem search time that operational ton is big and the data set change causes that binding relationship is set up in the complicated list design.
Summary of the invention
The present invention realizes the dynamic binding of data source and control through following method, with solve binding relationship in the complicated list design set up operational ton big with data set change cause search time length problem.
Data source data is described with action statement (such as SQL etc.), and action statement is resolved, and converts data set into.Data set comprises the field title and the field type of data source.Control is the display element of list, and control all has corresponding model, and composite control comprises other child controls.
1. the setting of binding relationship
Binding relationship is the incidence relation of data set field element and control.Binding relationship is specifically described with the binding relationship object, and the binding relationship object is a doublet, comprises binding relationship type and binding relationship value, promptly is expressed as (binding relationship type, binding relationship value).Binding relationship can have three types among the present invention: value, binary relation table and match pattern.Three types of available characters strings, numerical value or other symbols are represented.
If the binding relationship type is value, promptly monodrome is bound, and this data set field element is the binding relationship value; If bindtype is the binary relation table; Wherein, said binary relation table is used to be provided with the corresponding relation of data centralization field and control, for example; The binding of data set and table; The corresponding relation of data centralization field title and gauge outfit field title can be set, all corresponding relations are established as relation table, the binding relationship value i.e. relation table object for this reason; If bindtype is a match pattern, wherein, match pattern is a definition rule; As the relation maxim of binding elements and control property, use match pattern, the binding that can set up data set field element and control automatically; Such as the identical matched rule of title is set; What data set field title was identical with composite control child control title will bind automatically, and the binding relationship value is a matched rule, like the rules such as character identical match of character identical match and ignorecase.
The present invention is divided into simple binding and complex-bound to binding.The simple binding is single mapping, like the binding of control and data set field element, can realize through related control and data set daughter element, and promptly above-mentioned monodrome is bound situation.For the binding of complicacy, be composite control like control, a plurality of daughter elements of control will be bound with the data set field element, can be through binding relationship be set, the binding relationship object that to generate above-mentioned binding relationship type be binary relation table or match pattern.
2. the foundation of overall binding relationship matrix
Adopt overall binding relationship matrix to store binding relationship in the present invention, overall binding relationship matrix is a two-dimensional array.The data set field element that will have a binding relationship is converted into continuous integer (Field ID) successively as matrix column number; The control that will have a binding relationship is converted into continuous integer (control ID) successively as the row of matrix number, and the binding relationship object is set to the value of ranks corresponding position array element then.Wherein, sign available characters string, numerical value or other symbol of described data set field element and control are represented.In setting up process, find the row at Field ID place, if do not exist in overall binding relationship matrix new Construction Bank; Find the row at control ID place again, and if do not exist in overall binding relationship matrix newly-built row; The binding relationship object is set the value of ranks corresponding position array element.Equally, also can be with Field ID as the row of matrix number, as matrix column number, the binding relationship object is set to the value of ranks corresponding position array element then with control ID.
When list when xml file unserializing is model, restore overall binding relationship matrix.Recuperation is: in control xml markup modelization; Find bound flag; Is the bound flag unserializing binding relationship object; Binding relationship xml mark is to the conversion of binding relationship object, only need insert the binding relationship object to binding relationship type and binding relationship value and get final product, and according to said method the binding relationship object inserted in the overall binding relationship matrix then.
3. the maintenance of overall binding relationship matrix
After overall situation binding relationship matrix was set up, the binding relationship of data set field element and control changes just can be realized through changing overall binding relationship matrix.When a new data set field element will be set up binding relationship with control, only need the new column or row of registration, again the binding relationship object is inserted overall binding relationship matrix and get final product.After a data set field element and a plurality of control property were set up binding relationship, and data set is deleted and bound field element, the cancellation of binding only need be nullified the value of the field element column or row in the overall binding relationship matrix.When the control of setting up binding relationship, be tied to other data set field element, only need the original binding relationship of cancellation, fill out the new field element and the correspondence position of control with new binding relationship object.Variation for control also is same, and such as deleting certain control, then relative binding relationship all can be ineffective.Such as, the data source data storehouse sql statement of revising among the data set DataSet1 is select addressfrom information, but to have only address be binding elements to data centralization.The cancellation of the binding of original binding elements name and control; Only need in overall binding relationship matrix, search for the control that binding relationship is arranged with data set; Cancel the binding relationship of the name of also existence after finding binding relationship, and need not from all controls, search to control.
4. the storage of list and binding relationship
After data binding operation is accomplished, list will be from the memory to the physical medium on.Storing process is: like list serializing element is control, and there is binding relationship in control in overall binding relationship table, then takes out the binding relationship object, is stored in corresponding control after the serializing.
Adopt overall binding relationship matrix to store feasible implement easy to operate of binding of binding relationship; Only need read corresponding binding relationship object from overall binding relationship matrix just can implement corresponding binding; Can write a function or class object overall binding relationship is implemented unified the binding; Do not need to write the binding code respectively, greatly reduced the programming operation amount, and can more effectively guarantee the accurate operation of binding relationship with regard to concrete binding.And another beneficial effect of this method is to improve program run efficient significantly.Complicated list design, the bindings of data set and control very frequently, it is extremely important that the maintenance of overall binding relationship matrix just becomes.When binding relationship changes, no longer need search for the binding information of control again through the list system of this method design, only need to upgrade overall binding relationship matrix and get final product, solved that the binding relationship change causes in the complicated list search time length problem.

Embodiment
Illustrate embodiment of the present invention below in conjunction with accompanying drawing.
1. the storage of binding relationship in the xml file
In this embodiment, with three kinds of binding relationships among the present invention---value, binary relation table and match pattern are represented with character string Value, Table and Match respectively.The character identical match of in the Match type, representing character identical match and ignorecase respectively with character string Equal and EqualIgnoreCase.
In this embodiment, with xml file storage binding relationship, binding relationship direction memory such as Fig. 3.
For simple binding, for example to field element name among the control text1 of Text type and the data set dataset1 be bound, the binding relationship object be (Value, name), the xml file is when storing control into:
<Text?ID＝”text1”，Content＝””>
<Bind?ID＝”dataset1”/>
<BindRelation?Type＝”Value”，Relationname＝”inforValue”>
name
</BindRelation>
</Text>
For complex-bound, if binding relationship is the binary relation table, this moment, the binding relationship type was Table, and the binding relationship object is (Table, a mapping table object).The mapping table object representes that with the Map data structure Storage Mapping is right.Such as with two field element among the data set dataset1 (name, address) with form in (title, address) bind, the xml file is when storing control into:
<Table?ID＝”table1”>
TR name=" title "/
TR name=" address "/
<Bind?ID＝”dataset1”/>
<BindRelation?Type＝”Table”，Relationname＝”inforTable”>
<maping>
<ID1>name</ID1>
<iD2>Title</ID2>
</maping>
<maping>
<ID1>address</ID1>
<iD2>The address</ID2>
</maping>
</BindRelation>
</Table>
If binding relationship is a match pattern, this moment, the binding relationship type was Match, and the binding relationship object is (Match, a concrete matched rule).If concrete matched rule specifically is the character identical match of ignorecase, then the binding relationship object be (Match, EqualIgnoreCase).Such as field element among the data set dataset1 (name, address) with form in (Name Address) binds, and the xml file is when storing control into:
<Table?ID＝”table1”>
<TR?name＝”Name”/>
<TR?name＝”Address”/>
<Bind?ID＝”dataset1”/>
<BindRelation?Type＝”Match”，Relationname＝”inforMatch”>
EqualIgnoreCase
</BindRelation>
</Table>
2. binding relationship is the binding relationship object model from xml file unserializing
When the binding relationship type is value, when promptly monodrome was bound, the binding relationship value was the respective field element, uses string representation in the present embodiment; When the binding relationship type was match pattern, the binding relationship value was concrete matched rule, and promptly above-mentioned character identical match, the character identical match of ignorecase or other rules are used string representation in the present embodiment; When the binding relationship type was the binary relation table, the binding relationship value was the relation table object, uses string representation in the present embodiment.From the xml file, obtain the binding binding information then and be converted into the binding relationship object.For example, can in Java language, realize through setting up following binding relationship object model:
package?dataBind；
import?java.util.HashMap；
public?class?BindRelation{
// bindtype
public?enum?type{
Value，Table，Match
}；
// binding title
String?name；
// bindtype
type?relationType；
// if Value or Match type, storing value
String?value；
// if the Table type, it is right that storage is bound
HashMap<String，String>tableValue；
// convert xml element bindRelation into the BindRelation object
BindRelation?convertToRelation(org.dom4j.Element?bindRelation){
name＝bindRelation.attributeValue(″Relationname″)；
The conversion of //value type
if(bindRelation.attribute(″Type″).equals(type.Value)){
relationType＝type.Value；
value＝bindRelation.getText()；
}
The conversion of // table type
else?if(bindRelation.attribute(″Type″).equals(type.Table)){
relationType＝type.Table；
for(Object?object：bindRelation.elements()){
org.dom4j.Element?element＝(org.dom4j.Element)object；
String?ID1＝element.elementText(″ID1″)；
String?ID2＝element.elementText(″ID2″)；
tableValue.put(ID1，ID2)；
}
}
The conversion of // match-type
else?if(bindRelation.attribute(″Type″).equals(type.Match)){
relationType＝type.Match；
value＝bindRelation.getText()；
}
return?this；
}
}
3. the foundation of overall binding relationship matrix and maintenance
When list when xml file unserializing is model, restore and set up overall binding relationship matrix.Shown in Figure 4 like Fig. 1, as matrix column number and row number, the binding relationship object is as the value of ranks infall array element respectively for Field ID and control ID.After having set up binding relationship, be registered to overall matrix to Field ID, control ID and binding relationship object.Find the row at Field ID place, and if do not exist in overall matrix new Construction Bank; Find the row at control ID place again, and if do not exist in overall matrix newly-built row; Insert the ranks corresponding position to binding relationship ID.
Recuperation is: at first set up binding relationship overall situation matrix object.Control xml mark is carried out modelling, find bound flag, turn to the binding relationship object to the binding relationship tagged object, insert control Tag ID and bound flag ID corresponding position in the overall matrix.Control ID and binding ID all can be obtained by control xml mark; Binding relationship xml mark is to the conversion of binding relationship object; Only bindtype need be inserted the type attribute of object; Bind title and insert the name attribute of object, value or matched character string are inserted the value attribute of object, and mapping is to inserting the map object.
Following list XML file,
<DataSet?name＝”dataset1”>
<ColumnName>name</ColumnName>
<ColumnName>address</ColumnName>
</DataSet>
<Text?ID＝”text1”，Content＝””>
<Bind?ID＝”dataset1”/>
<BindRelation?Type＝“Value”，Relationname＝”text1Bind”>
name</BindRelation>
</Text>
Recuperation is: set up overall binding relationship matrix object matrix; Control text1 is carried out modelling; Find bound flag Bind, (Value name) inserts dataset1 and text1 corresponding position to convert binding relationship BindRelation mark into binding relationship object doublet.
The data binding relation is variable in the list design.Binding relationship possibly be cancelled or set up new relation after setting up.Need safeguard overall binding relationship matrix.Dynamic Maintenance such as Fig. 2 of overall situation matrix specifically describe as follows:
Overall situation binding relationship matrix has global flag rower r and row mark c, and the head of every row and every row has the index sign again in addition.Global flag is represented the quantity of current available row and column; The binding relationship number of expression one's own profession of index sign or row.Operation and Maintenance to overall binding relationship matrix is following:
(1) register binding.If distributed row or row, then overall rower or row mark subtract 1; Inserting binding relationship is not to replace original binding relationship, and corresponding row perhaps is listed as index increases by 1; Detect overall rower or row marks, equal 0 if having, then compress overall matrix, overall matrix allocation fixed line number and columns vacant is provided with overall rower and marks number with row.
(2) nullify binding relationship.If full line or permutation are nullified, the index that row or row then are set is 0; If nullify certain binding relationship, corresponding row perhaps is listed as index and reduces 1.
(3) compress overall matrix.Detect rower and row mark,, then delete one's own profession or these row as promising 0.
Here global flag shows remaining row or row, can be used as the sign of condensation matrix; Rower or row mark index, whether expression one's own profession or row are effective, before overall matrix compression, can change matrix size like this.
For example, above process can realize through following code in Java language:
// newly-built binding relationship storage matrix
Matrix?matrix＝new?Matrix()；
// what import into is the xml node of Text, obtains the ID property value according to node
String?controlName＝TextXml.attributeValue(″ID″)；
// obtain the title of the data set of binding among the Text
String?bindName＝TextXml.element(″Bind″).attributeValue(″ID″)；
// newly-built binding relationship
BindRelation?bindRelation＝new?BindRelation()；
// convert the binding relationship of xml form into the binding relationship object
bindRelation.convertToRelation(TextXml.element(″BindRelation″))；
// deposit binding relationship in control title and data set corresponding position
matrix.put(bindName，controlName，bindRelation)；
Wherein, the Matrix class is following code:
package?dataBind；
import?java.util.HashMap；
import?java.util.Stack；
public?class?Matrix{
// storage binding relationship object is used the two-dimensional array representing matrix
BindRelation[][]store；
