Embodiment described in following exemplary embodiment does not represent all embodiment party consistent with the present invention Formula.On the contrary, they only with describe in detail in appended claims, the present invention some in terms of mutually one The example of the apparatus and method caused.

Fig. 1 is the flow chart according to a kind of method for editing text shown in an exemplary embodiment, such as Fig. 1 institute Showing, text edit methods may comprise steps of.

In a step 101, text editing operations is received.

In a step 102, text editing operations in-point in text and editor's terminal are determined.

Wherein, the initial character during in-point is the content of text of request editor and the original position of text Between offset location, editor's terminal is last character and the text in the content of text of request editor Offset location between end position.

In step 103, by in-point, terminal is edited and between in-point and editor's terminal Content of text be associated storage.

At step 104, according to text editing operations editor's content of text.

In sum, the method for editing text provided in disclosure embodiment, by by text editing operations In-point, editor's terminal and the content of text between in-point and editor's terminal are associated depositing Storage so that terminal without caching the full content in text, but can only cache in-point and volume Collect the partial content between terminal, and then solve to need to consume greatly during terminal buffers text in correlation technique The problem of amount internal memory；Reach to reduce terminal and needed the content of caching, and then reduce need to take interior The effect deposited.

The method provided in disclosure embodiment, may be used in the text editing of the multiple application such as note.

Fig. 2 A is the flow chart according to a kind of method for editing text shown in an exemplary embodiment, such as Fig. 2 A Shown in, text edit methods may comprise steps of.

In step 201, text editing operations is received.

When user needs to edit the content of text in text, user can apply text editing Operation, accordingly, terminal can receive text editing operations.

Such as, when user wants a certain position in text to increase content of text newly, user can be by Location cursor moves to this position, then performs input operation；Wherein, input operation can be that user passes through The input operation of input through keyboard, it is also possible to be user's input of being carried out by the insertion function in toolbar inputting Operation, this is not limited by the present embodiment.

When user wants a certain character deleting in the content of text of text, user can will position light The mobile position to this character of mark；When positioning cursor and moving the position before this character, User can use ' delete ' key to apply backward deletion action；In location, cursor moves after this character During position, user can use ' backspace ' key to apply forward direction deletion action.Wherein, in the present embodiment Backward deletion action is specific bit cursor when being positioned at a certain position, corresponding to user's pressing once ' delete ' key Operation；Forward direction deletion action is specific bit cursor when being positioned at a certain position, and user presses once ' backspace ' Operation corresponding to key.

When user wants the part content of text deleting text, user can select text content, Then ' backspace ' key or ' delete ' key is used to perform selected deletion action.

When user wants to be replaced a part of content of text in content of text, user can input to be needed Content of text to be searched, then performs the content of text of the lookup replaced in region is replaced to other texts The replacement operation of content；Wherein, replacing region can be the region that user selects, it is also possible to be from text literary composition The original position of part is to the Zone Full of end position, it is also possible to be from location cursor present position to head The region of last character position of the secondary content of text occurring searching, this is not done by the present embodiment Limit.

When user needs to carry out the part content of text in text form change, user can choose Text content, then performs the change operation of the form to the content of text chosen.

In step 202., text editing operations in-point in text and editor's terminal are determined.

After terminal receives text editing operations, for the execution of subsequent step, terminal may determine that text Edit operation in-point in text and editor's terminal.

Wherein, the initial character during in-point is the content of text of request editor and the original position of text Between offset location, editor's terminal is last character and the text in the content of text of request editor Offset location between end position.

When actual realization, according to the difference of the text editing operations that terminal receives, terminal determines edits The step of point and editor's terminal can include following several possible implementation:

In the implementation that the first is possible,

If text editing operations is input operation, then according between location cursor and the original position of text Side-play amount calculate in-point, and according to location cursor and the end position of text between side-play amount Calculate editor's terminal；

If the text editing operations received is input operation, then terminal can calculate from text Beginning position is to the first side-play amount of cursor position, location, by the side-play amount between original position for calculating The position of the first side-play amount obtained is defined as in-point；Meanwhile, terminal calculates the end from text Position is to the second side-play amount of cursor position, location, by the side-play amount between end position for calculating To the position of the second side-play amount be defined as editing terminal.

In the implementation that the second is possible,

If text editing operations is forward direction deletion action, then according to place after cursor slow astern the character of location Position and the original position of text between side-play amount calculate in-point, and according to location cursor work as Side-play amount between position and the end position of text at front place calculates editor's terminal；

If the text editing operations that terminal receives is forward direction deletion action, then terminal can calculate from text The original position of file is inclined to the position cursor position after present position slow astern character the 3rd Shifting amount, is defined as in-point by the position that the side-play amount between original position is the 3rd side-play amount；Meanwhile, Terminal calculates from the end position of text to the 4th side-play amount of location cursor present position, will be with Side-play amount between end position is that the position of the 4th side-play amount is defined as editing terminal.

In the implementation that the third is possible,

If text editing operations is backward deletion action, then the position being currently located according to location cursor and text Side-play amount between the original position of file calculates in-point, and according to location cursor advance a character it Side-play amount between position and the end position of text at rear place calculates editor's terminal；

If the text editing operations received is backward deletion action, then terminal can calculate from text Original position to location cursor position the 5th side-play amount, by the side-play amount between original position be The position of the 5th side-play amount is defined as in-point；Meanwhile, terminal calculate from the end position of text to Location cursor is the 6th side-play amount of position after a character is advanced in current location, will be with end position Between the position that side-play amount is the 6th side-play amount be defined as edit terminal.

In the 4th kind of possible implementation,

If text editing operations is the selected deletion action to selected content of text, then according to selected text In content, the side-play amount calculating between position and the original position of text at first character place is edited Point, according to the end position of the position at last character place in the content of text chosen and text it Between side-play amount calculate editor terminal；

If the text editing operations received is that then terminal can be counted to the selected deletion action choosing content Calculate the 7th the first character position from the original position of text to the content of text chosen Side-play amount, is defined as in-point by the position that the side-play amount between original position is the 7th side-play amount；With Time, terminal can also calculate the last character from the end position of text to the content of text chosen The 8th side-play amount between symbol position, by the position that the side-play amount between end position is the 8th side-play amount Put and be defined as editing terminal.

In the 5th kind of possible implementation,

If text editing operations is replacement operation, then according to replacing the content of text occurring searching in region first In first character position and the original position of text between side-play amount calculate in-point, and root Position and text according to last character replaced in the content of text that in region, last appearance is searched Side-play amount between end position calculates editor's terminal；

If the text editing operations received is replacement operation, then during terminal may determine that replacement region first The position of the first character in the content of text that appearance is searched, calculates from the original position of text to determining First character position between the 9th side-play amount, be the 9th skew by the side-play amount between original position The position of amount is defined as in-point；Meanwhile, in during terminal determines replacement region, there is the text searched in last The position of last character in appearance, calculates from the end position of text to the last character determined Tenth side-play amount of the position of symbol, determines the position that the side-play amount between end position is the tenth side-play amount For editor's terminal.

In the 6th kind of possible implementation,

If text editing operations is the change operation of the form to the content of text chosen, then according to the text chosen In content, the side-play amount calculating between position and the original position of text at first character place is edited Point, according to the end position of the position at last character place in the content of text chosen and text it Between side-play amount calculate editor terminal.

If the text editing operations received is that the form choosing content is changed operation, then terminal can be counted Calculate the tenth the first character position from the original position of text to the content of text chosen One side-play amount, is defined as in-point by the position that the side-play amount between original position is the 11st side-play amount； Meanwhile, terminal can also calculate last from the end position of text to the content of text chosen The 12nd side-play amount between character position, is the 12nd skew by the side-play amount between end position The position of amount is defined as editing terminal.

Such as, it is as a example by backward deletion action by text editing operations, refer to Fig. 2 B, after terminal receives When deletion action, the location location A that is marked in text of light, then terminal can by location A and from B location after location A one character of advance is defined as in-point and editor's terminal；It is similar to, with literary composition As a example by this edit operation is replacement operation, refer to Fig. 2 C, replacing region is the shadow region in figure, searches Content of text be ' content of text ', then location of C and D position can be defined as in-point and volume by terminal Collect terminal.

Need explanation on the other hand, when text editing operations is the volume that the content of text selected adds annotation When collecting operation, terminal can calculate the inclined of the first character in the content of text selected from original position to user Shifting amount, is defined as in-point by the position that the side-play amount between original position is calculated side-play amount； Meanwhile, last character during terminal can also calculate the content of text selected from end position to user Side-play amount, is defined as editor eventually by the position that the side-play amount between end position is calculated side-play amount Point, the present embodiment does not repeats them here.

In step 203, by in-point, terminal is edited and between in-point and editor's terminal Content of text be associated storage.

After terminal determines in-point and editor's terminal, terminal may determine that to be positioned in text and edits Content of text between point and editor's terminal, then by in-point, editor's terminal and the text determined Hold and be associated storage.Being as a example by backward deletion action by text editing operations, terminal can be by location A, B Position and ' civilian ' between location A and B location are associated storage.

When actual realization, terminal can safeguard that one is cancelled storehouse, when terminal receives text editing operations Time, terminal can be by the text of the in-point corresponding to text editing operations, editor's terminal and correspondence Hold combination to store to cancelling in storehouse.And when terminal receives multiple text editing operations, terminal is permissible The in-point corresponding to text editing operations, editor's terminal and the content of text that to receive successively every time Store to cancelling in storehouse.

It should be noted is that, when text editing operations is input operation, in-point in text And there is no content of text between editor's terminal, now terminal can be by the literary composition between in-point and editor's terminal This curriculum offering is empty.

Need explanation on the other hand, when text editing operations is the volume that the content of text selected adds annotation During volume operation, terminal can use content in the annotation that user adds replace in-point and editor's terminal it Between content of text store.

In step 204, according to text editing operations editor's content of text.

Such as, it is still that as a example by backward deletion action, deletion is in location A by terminal by text editing operations And ' civilian ' between B location.

It should be noted that the present embodiment simply first carries out by terminal as a example by performing step 204 after step 203, When actual realization, terminal performs step 203 after can also first carrying out step 204, or performs step simultaneously 203 and step 204, it is only necessary to ensure that step 203 and step 204 perform after step 202, right Its actual execution sequence does not limit.

In step 205, destruction operation is received；

After the content of text of text is edited by terminal, when user wants to return to content of text During state before editor, user can click on and cancel button, and accordingly, terminal can receive and cancel behaviour Make.

It should be noted that step 205 is step 201 to the step performed after step 204, in reality When realizing, step 201 to step 204 can perform repeatedly before step 205, it is also possible to performs once, This is not limited by the present embodiment.

In step 206, in-point, editor's terminal and content of text select from respectively organizing of storage and removes One group of in-point, editor's terminal and the content of text that pin operation is corresponding；

Wherein, corresponding with destruction operation one group of in-point, editor's terminal and content of text refer to: terminal Before receiving destruction operation, the in-point corresponding to text editing operations that the last time receives, Editor's terminal and content of text.

When actual realization, terminal can select storehouse to be in the in-point at storehouse top, volume from cancelling Volume terminal and content of text, the in-point that selection is obtained, editor's terminal and content of text as with this One group of in-point, editor's terminal and the content of text that destruction operation is corresponding.

In step 207, the content of text using selection to obtain is replaced and is in what selection obtained in text Content of text between in-point and editor's terminal.

Terminal can use and select the content of text that obtains to replace in text to be in the editor selecting to obtain to rise Content of text between point and editor's terminal.

Such as, terminal selects in-point, editor's terminal and content of text are followed successively by location A, B position Put and ' civilian '；Then terminal can use ' civilian ' to replace in text to be between location A and B location Content of text, also will ' civilian ' add between location A and B location.

It should be noted that after terminal performs to cancel, when user wants the text recovered before cancelling civilian During part, user can also click on recovery button, and accordingly, terminal can receive recovery operation.Connect in terminal After receiving recovery operation, terminal can select the in-point corresponding with recovery operation, editor's terminal and Content of text between in-point and editor's terminal, then uses and selects the content of text obtained to replace text In file in-point and editor terminal between content of text.

When actual realization, after terminal execution text is cancelled, the editor that selection obtains can be risen by terminal Point, editor's terminal and the content of text combination replaced store to recovering in storehouse.Further, connect when terminal When receiving repeatedly destruction operation, terminal can be by the in-point corresponding to each destruction operation, editor's terminal And content of text combines successively and stores to recovering in storehouse.Hereafter, when terminal receives recovery operation, Terminal can select in-point, editor's terminal and the content of text recovering to be in storehouse top in storehouse, will Select the in-point obtained, editor's terminal be defined as with content of text the in-point corresponding with recovery operation, Editor's terminal and content of text.

Additionally, after terminal performs text recovery, in-point, editor that selection can be obtained by terminal are whole Point and the content of text combination replaced store to cancelling in storehouse, and the present embodiment does not repeats them here.

In sum, the method for editing text provided in disclosure embodiment, by by text editing operations In-point, editor's terminal and the content of text between in-point and editor's terminal are associated depositing Storage so that terminal without caching the full content in text, but can only cache in-point and volume Collect the partial content between terminal, and then solve to need to consume greatly during terminal buffers text in correlation technique The problem of amount internal memory；Reach to reduce terminal and needed the content of caching, and then reduce need to take interior The effect deposited.

It should be noted that refer to Fig. 2 D, before performing step 203, terminal can also carry out as follows Step:

In a step 208, it is input operation, forward direction deletion action or backward deletion when text editing operations During operation, whether the history text edit operation that detection text editing operations received with the last time associates Operation, if testing result is for being operation associated, then performs step 209；If testing result is not for being association Operation, then perform step 203.

Wherein, at least one during this step can include following detection mode:

The first:

Whether detection text editing operations and history text edit operation are same type of edit operations；

Whether terminal detection text editing operations and history text edit operation are same type of edit operations, If testing result is for being same type of edit operation, then terminal may determine that text editing operations and history Text editing operations is operation associated, otherwise, it not the most operation associated.

Such as, text editing operations is input operation, and the history text edit operation that the last time receives is also Be input operation, then terminal may determine that text editing operations and history text edit operation are operation associated. And if text editing operations is input operation, and history text edit operation be forward direction deletion action or after To deletion action or replacement operation, then terminal may determine that text editing operations and history text edit operation It not operation associated.

It should be noted that it is equal to the purpose of deletion action or backward deletion action before execution due to user Being to delete the content of text in text, so in the present embodiment, terminal can be by forward direction deletion action Being defined as operation associated with backward deletion action, this is not limited by the present embodiment.

The second:

Whether detection text editing operations and history text edit operation are editor's position continuous print edit operations；

Terminal can also detect text editing operations and whether history text edit operation is editor position continuous print Edit operation, if testing result is for being editor's position continuous print edit operation, then terminal may determine that text Edit operation and history text edit operation are operation associated, otherwise, it not the most operation associated.Wherein, compile Collect position refer to the in-point of text editing operations continuously or edit terminal and history text edit operation In-point or editor's terminal are same point.

The third:

Whether the edit session interval of detection text editing operations and history text edit operation is less than the scheduled time Interval.
