Referring to Fig. 1, Fig. 1 is a kind of flow diagram of information processing method provided by the embodiments of the present application.Such as Fig. 1 institute
Show, which may include:
101, object identity is received.
(be otherwise known as Observer Pattern model (Model) view (View) mode, source listener (Listener) mould sometimes
Formula or subordinate's mode) be software design pattern one kind.In such mode, a target piece management is all to depend upon it
Observer's object, and the state of itself change when actively give notice.This is usually mentioned through each observer of calling
The method of confession is realized.Such mode is usually used to realization event handling system.Observer Pattern has many implementations, from
It fundamentally says, which must include two roles: observer and observed person.
In a kind of possible embodiment, the observed person (Subject) in same software can be business number
According to, picture etc., observer (Observer) can be user interface etc., in the presence of " observation " between observer and observed person
Logic association, when observed person changes, observer will observe such variation, and make corresponding sound
It answers.It is understood that the interactive relationship between observer and observed object cannot be embodied as calling directly between class, it is no
It then will just make closely to be coupled together between observer and observed object, and fundamentally violate the original of object oriented designing
Then.Before the variation of observer " observation " observed person, the monitoring register method of observed person need to be called, by pair of observer
As mark passes to observed person, i.e. observed person's object identity for receiving observer, the step be before realizing and monitoring, it is complete
At the process of registration.Specifically, the object identity be observer reference, reference be in java, the operation of object all with
Association is generated therewith by means of reference, by operating associated reference, to achieve the purpose that object needed for operating, that is, is quoted, is
It, can be with analogy pointer, address for operation object.Wherein, it may include the identity of observer in above-mentioned reference, connect

Wherein, the information processing unit in the application may include mobile phone based on android system, tablet computer, palm electricity
Brain, laptop, mobile internet device MID (mobile internet devices, MID) or wearable device etc. can
To install the electronic equipment of application software, above- mentioned information processing unit is only citing, and non exhaustive, including but not limited to above-mentioned letter
Cease processing unit.Certainly in practical applications, above- mentioned information processing unit is also not necessarily limited to above-mentioned realization form, such as can also wrap
It includes: car-mounted terminal.
102, it whether there is object identity identical with the object identity in the object identity of judgement storage, judging to deposit
There is no in the case where object identity identical with the object identity in the object identity of storage, step 103 is executed.
In a kind of possible embodiment, after the object identity that observer's transmitting is received based on observed person, it is observed
The object identity is stored in set by person.Wherein, collection is combined into the set of weak reference, is come in a manner of key-value (key-value)
Storage object mark.
Specifically, when Android is developed, there are four types of references, and the performance in order to optimization application can be used, these four draw
With are as follows: strongly reference, (StrongRefernce), soft reference (SoftReference), weak reference (WeakReference), void are drawn
With (PhantomReference).Wherein, strongly reference can direct access target object, object associated by strongly reference is in office
When wait all will not by Memory recycle, no matter and whether weak reference memory sufficient, find certain an object reference only have it is weak
Quoting current weak reference will be recovered.The problem of in order to evade RAM leakage, observed person will in the embodiment of the present application
The mark of the observer is stored in the array of strongly reference, and is stored in the sparse array of weak reference
(SparseWeakArray), not only RAM leakage will not be caused because of strongly reference in this way, but also SparseWeakArray ratio
It plays other chained list hash and more saves memory headroom.
In above-mentioned set, i.e., stored in a manner of key-value in the sparse array (SparseWeakArray) of weak reference
The object identity of one or more observers, wherein in the cryptographic Hash of the position of key (key) storage observer, it is to be appreciated that
The cryptographic Hash of different observers is different, and in the position of value (value), the corresponding identification information of storage observer's cryptographic Hash, that is, draw
With.When some observer delivers the object identity, observed person takes the Kazakhstan of the object of the currently monitored data variation first
Uncommon value, object, that is, observer of monitoring data variation.After receiving object identity, the object identity of storage can be first judged
In whether there is object identity identical with the object identity, can be and cryptographic Hash first determined according to the object identity, sentence later
Whether there is cryptographic Hash identical with the cryptographic Hash in the cryptographic Hash of disconnected storage, in the cryptographic Hash for judging storage there is no with
In the case where the identical cryptographic Hash of the cryptographic Hash, determines and object identical with the object identity is not present in the object identity of storage
Mark will execute step 103.There are the feelings of object identity identical with the object identity in the object identity for judging storage
Under condition, the object identity can be abandoned.There are the feelings of cryptographic Hash identical with the cryptographic Hash in the cryptographic Hash for judging storage
Under condition, the corresponding object identity of the cryptographic Hash of object identity replacement storage can be used.
It should be noted that including object identity in the information that observer transmits to observed person, received in observed person
After the object identity transmitted to observer, in the corresponding set of data observed by the object identity of observer is stored in.Its
In, an observer includes multiple data, each data is corresponding with the set of a weak reference.
103, the object identity is stored.
Based in step 102 judgement when front transfer object identity observer cryptographic Hash whether with have stored in set
In cryptographic Hash inquired, shown by query result, if the not observer with the transmitting object identity in current collection
The same cryptographic Hash of cryptographic Hash, then store the object identity.Wherein, it is still and is stored according to the structure of key-value, that is, breathe out
Uncommon value is used as key, which is that the corresponding value of the cryptographic Hash stores.
Whether identical it is possible to further compare the address in new object mark and old object identity, address here is
Address in the corresponding object identity of cryptographic Hash, can not also compare, and new object identity can be replaced directly to old pair
As mark, if finding after the comparison, new object identity as old object identity, can not also be replaced, and it is new right directly to delete
As mark.
It is not that storage should immediately after receiving an object identity in the information processing method described in Fig. 1
Object identity, but determine storage object identity in be not present object identity identical with the object identity in the case where,
The object identity is just stored, can carry out repeating storage to avoid the object identity to the same observer, to send data
When update message, repeat to send repeatedly, so as to economize on resources for the same observer.
Referring to Fig. 2, Fig. 2 is the flow diagram of another information processing method provided by the embodiments of the present application.Such as Fig. 2
Shown, which includes:
201, the information including object identity and Data Identification is received.
It, can be to observed person in the case that observer needs monitored data to change in a kind of possible embodiment
The information including object identity and Data Identification is sent, observed person can receive the information later.It is understood that one
A Data Identification can correspond to multiple object identities, i.e. a data can be monitored by multiple observers.Wherein, object identity refers to
The mark of observer, the event action to be monitored and monitor, monitor are used to after event occurs execute the interface of operation
Definition, it should be noted that in developer develops and realizes, the event interface to be monitored need to be realized in this side of observer, it is complete
Operation content after occurring at the time a, it can event interface is defined to be abstracted all event types by observer, works as quilt
After data in observer change, it can actively be adjusted back to observed person by interface.It is understood that different data
Source variation is adjusted back by different interfaces to observer.Object identity can be address, be also possible to title, can also be other
Information, this embodiment is not limited.
It should be noted that the object identity for receiving an observer can be primary received, it is also possible to repeatedly connect
It receives, there are a kind of situations, and after observer is broken down, the same observer may be repeatedly to observed person's transmitting pair
As mark.
In the realization of software development for example, now with observer A registration monitored in data source two data x and
The variation of y, then observer need to not only write itself " address " in object identity, also write the mark of x and y, Yi Jiyao
Realize two interfaces of x and y variation.
202, cryptographic Hash is determined according to the object identity.
Wherein, cryptographic Hash is also known as hash function or hashing algorithm, also known as hash function, and cryptographic Hash is a kind of from any one
The method of small number " fingerprint " is created in data.Hashed value usually uses the character string of a short random letters and number composition
To represent.In fact, default that object class provides is realized guarantees that the cryptographic Hash of each object is different (in the memory of object really
A cryptographic Hash is returned by special algorithm on the basis of location).So can store in the position of key, new observation is being received
When the mark of person, whether the cryptographic Hash for capableing of cryptographic Hash and current observer in set in comparison sheet is identical.
In a kind of possible embodiment, the Hash of observer can be obtained by the hashCode () method of object class
Value.It wherein, is the address value of the object in memory using the cryptographic Hash that this method returns, cryptographic Hash is also that object is stored to Kazakhstan
The important evidence of uncommon table.
After receiving the information including object identity and Data Identification, cryptographic Hash can be determined according to the object identity,
Hash operation is carried out to the object identity and obtains cryptographic Hash.
203, it whether there is cryptographic Hash identical with the cryptographic Hash in the cryptographic Hash of judgement storage, in the Kazakhstan for judging storage
In the case where there is cryptographic Hash identical with the cryptographic Hash in uncommon value, step 204 is executed, in the cryptographic Hash for judging storage not
In the case where cryptographic Hash identical with the cryptographic Hash, step 205 is executed.
Wherein, the specific implementation process of step 203 can be found in the description in embodiment corresponding to above-mentioned Fig. 1 to step 102,
Here it will not continue to repeat.
204, using the corresponding object identity of the cryptographic Hash of object identity replacement storage.
In a kind of possible embodiment, it can be in above-mentioned set based on step 202 and step 203 and pass through meter
Length (length gathered) the progress complementation operation for calculating cryptographic Hash and table obtains an integer value, which is exactly that new element will be deposited
The position (being index value) put, if without storing any element on the corresponding position of index value, it can be directly by the Hash
The corresponding object identity of cryptographic Hash is stored on the position of the corresponding value of cryptographic Hash by the storage of value in this position.It can also
In the case where to have stored element on the corresponding position of index value, existing object cryptographic Hash, judgement are inquired in set
In table whether there is cryptographic Hash identical with the cryptographic Hash the case where, can also inquire at the very start in current table and whether deposit
The cryptographic Hash identical with the cryptographic Hash the case where.
In the case where there is cryptographic Hash identical with the cryptographic Hash in the cryptographic Hash for judging storage, the object mark is used
Know the corresponding object identity of the cryptographic Hash for directly replacing storage.It is possible to further to the object mark stored on value
Knowledge is compared, and in the identical situation of the object identity of the object identity and storage, can directly abandon the object identity, and
It does not need to replace.
Specifically, it can be determined in the cryptographic Hash for judging storage there is no after cryptographic Hash identical with the cryptographic Hash
Object identity identical with the object identity is not present in the object identity of storage, executes step 205.
205, the object identity is stored.
Wherein, the specific implementation process of step 205 can be found in the description in embodiment corresponding to the Fig. 1 to step 103, this
In will not continue to repeat.
206, monitored data identifies whether identified data change.
After receiving the information including object identity and Data Identification, monitored data it can be identified in real time
Whether data change.Step 206 can execute parallel with step 202, can also serially execute.
In the realization of software development, for data x in a data source, if data x is changed, data x hair
Send Data Identification to data source, i.e. observed person, after observed person receives Data Identification, traversal current data x is corresponding
The set of observer is stored with the observer for determining survival of observer in set, and sends data to observer and change message.
207, when listening to the data that Data Identification is identified and changing, judge the corresponding object of the first object identity
Whether survive, in the case where judging that the corresponding object of the first object identity is survived, executes step 208, judging first
In the case that the corresponding object of object identity is not survived, step 209 is executed.
In a possible embodiment, it changes when observed person listens to the data that Data Identification is identified
When, it can first judge whether the corresponding object of the first object identity survives, judge that the corresponding object of the first object identity deposits
In the case where work, step 208 can be executed, it, can be in the case where judging that the corresponding object of the first object identity is not survived
Execute step 209.First object identity is any right in the corresponding all object identities of Data Identification of observed person's storage
It is any object identity in the entire set of traversal in the corresponding all object identities of Data Identification as mark.Work as prison
When the data for hearing that Data Identification is identified do not change, continue to monitor.Whether judge the corresponding object of the first object identity
Reference count method (Reference Counting) can be used in survival, and Reachability Analysis Algorithm also can be used
(Reachability Analysis), the application is without limitation herein.Reference counting algorithm shows object and adds a reference
Counter, as soon as when there is a place to quote it, counter adds one；When quoting failure, just subtract one；When counter is not 0,
Judge that the object is survived；Otherwise it is judged as dead (counter=0).This method realizes that simply, judgement is efficient, and the disadvantage is that nothing
Mutual circulation is quoted between method solves the problems, such as object.And Reachability Analysis Algorithm also referred to as quotes chain method, by a series of
The object of GC Roots is searched for downwards since these nodes as starting point, is searched for the path passed by and is known as quoting chain, when one
Object to GC Roots do not have any reference chain be connected (i.e. from GC Roots to this object unreachable) when, it was demonstrated that this object is not
It can use.The GC Roots can be the object quoted in Java Virtual Machine stack (the local variable table of stack frame), be also possible to local
JNI reference object can also be the object of the middle constant in method area, the reference of class static attribute in method stack.
208, data are sent to the corresponding object of the first object identity and changes message.
In a possible embodiment, in the case where judging that the corresponding object of the first object identity is survived, table
There is also can send data change to the corresponding object of the first object identity and disappear the corresponding observer of bright first object identity
Breath.Wherein, data change message may include the Data Identification, for showing data change message for which data
Data change message；, data, which change message, to include data information, and data information may include that the Data Identification is corresponding
The information of changed data in data, data information can also include the content before the corresponding data of the information change
And/or the content after changing.It is understood that when storing the object identity of observer, observer's
Object identity actually only stores in set once, so, when sending, data change only is sent to observer and is disappeared
When breath, a data only are sent to the same observer and change message.
209, the first object identity of storage is deleted.
In a possible embodiment, in the case where judging that the corresponding object of the first object identity is not survived,
Show that the corresponding observer of the first object identity has been not present, the first object identity of storage is nonsensical, therefore, can be with
The first object identity for deleting or removing storage in corresponding set, can be to avoid the waste of memory, so as to save memory.
Further, if observer cancels observation, i.e., observer tells observed person to cancel observation, observed person
Remove or delete from this collection the mark of observer.
210, when the corresponding data of the Data Identification are deleted or are removed, the corresponding institute of the Data Identification of storage is deleted
There is object identity.
In a kind of possible embodiment, when the corresponding data of the Data Identification are deleted or are removed, i.e., at one
A data in data source are recovered, and delete the corresponding all object identities of the Data Identification of storage, i.e., traversal is observed
The object identity of person's storage deletes being recovered in the corresponding object identity of all Data Identifications, namely current observed person
The corresponding set of data in the object identity of observer that stores can all be deleted, the method for deletion can be remove it is all
Cryptographic Hash and corresponding objects mark, it is consistent with the mark for the object that the removal is not survived, it is also possible to directly empty set, this
Apply herein without limitation.If with the mark of the storage of array of strongly reference, then current data source or data source wherein
When one data is recovered, reference will not be recycled, is easy to happen RAM leakage, and the embodiment of the present application uses weak reference
The problem of set storage, observer can be recovered in the system, evade RAM leakage.
It is not that storage should immediately after receiving an object identity in the information processing method described in Fig. 2
Object identity, but determine storage object identity in be not present object identity identical with the object identity in the case where,
The object identity is just stored, can carry out repeating storage to avoid the object identity to the same observer, to send data
When update message, repeat to send repeatedly, so as to economize on resources for the same observer.
Referring to Fig. 3, Fig. 3 is a kind of structural schematic diagram of information processing unit provided in an embodiment of the present invention.Such as Fig. 3 institute
Show, which may include:
