Abstract
The invention discloses a method and device for storing a JAVA object. The method provided by the invention comprises the following steps: searching a handle achieving a preset condition in the handles corresponding to the discarded JAVA object when the JAVA object newly established needs to be stored; and storing the JAVA object newly established into a storage space occupied by the discarded JAVA object corresponding to the searched handle. By adopting the technical scheme in the invention, the problems that much processing time and more processing resources are wasted and the processing speed of a JAVA card is reduced when the garage recycle is carried out on the JAVA object in the prior art are solved.
Description
Technical field
The present invention relates to technical field of intelligent card, relate in particular to a kind of storage means and device of JAVA object.
Background technology
The JAVA card is a kind of smart card that can move the JAVA program, the program of moving in the JAVA card is applet (Applet), card has been realized the system application DLL (dynamic link library) (API of the needed running environment of operation Applet program, the virtual machine of explaining the JAVA language and standard, Application Programming Interfaces), these functions have guaranteed that the Applet program can move on the JAVA card.
Garbage reclamation is a big characteristic of JAVA language, different with C Plus Plus, the JAVA language can be autonomous judge the JAVA object that does not re-use, i.e. Fei Qi JAVA object is when the JAVA object no longer is cited, when perhaps the Applet program can't find the JAVA object, this JAVA object is discarded JAVA object, the JAVA language can reclaim it after finding discarded JAVA object, so that newly-built JAVA object has enough storage spaces.JAVA is to liking memory allocated space from the JAVA heap, the JAVA heap is the data storage area of JAVA, JAVA heap major part on the JAVA card is on EEPROM (Electrically Erasable Programmable Read Only Memo) (EEPROM, Electrically Erasable Programmable Read-Only Memory).
In the prior art, the method for the JAVA object being carried out garbage reclamation is mainly following two kinds, is specially:
First method, mark-sweep-out method: mark-removing gatherer at first travels through all JAVA objects and the accessibility JAVA object of mark, scan storehouse then seeking unlabelled JAVA object (i.e. Fei Qi JAVA object), and discharge their internal memory, be i.e. the discarded JAVA object of deletion.
In above-mentioned first method, when the JAVA object that deletion is discarded, also relate to the operation that the JAVA object moves, for example JAVA object A, B, C, D are stored in the JAVA card in order, wherein the JAVA object B is discarded JAVA object, after the deletion JAVA object B, need JAVA object C and D be moved forward in proper order, therefore when the JAVA object that deletion is discarded, also need to carry out the move operation of JAVA object.
Because the JAVA object storage in the JAVA card on EEPROM, therefore when carrying out garbage reclamation, can be carried out a large amount of read-write operations to EEPROM, this has just expended more processing time and the processing resource of JAVA card, has reduced the processing speed of JAVA card.
Second method, mark-compression method: mark-compression gatherer at first travels through JAVA object and the accessibility JAVA object of mark, then the JAVA object tools of mark in new storage space, so that compress storehouse.
In above-mentioned second method, the JAVA object of never mark is that useful JAVA object is put together in fact, this method need be carried out very many JAVA object move operations, therefore also can carry out a large amount of read-write operations to EEPROM, this has also expended more processing time and the processing resource of JAVA card, has reduced the processing speed of JAVA card.
Summary of the invention
The embodiment of the invention provides a kind of storage means and device of JAVA object, in order to solve exist in the prior art the JAVA object is carried out garbage reclamation the time, expended the more processing time and handled resource, reduced the problem of the processing speed of JAVA card.
Embodiment of the invention technical scheme is as follows:
A kind of storage means of JAVA object, the method comprising the steps of: when needs are stored newly-built JAVA object, in the handle of discarded JAVA object correspondence, search and satisfy pre-conditioned handle; With described newly-built JAVA object storage in the shared storage space of the discarded JAVA object of the handle correspondence that finds.
A kind of memory storage of JAVA object comprises: search the unit, be used in the handle of discarded JAVA object correspondence, searching and satisfying pre-conditioned handle when needs are stored newly-built JAVA object; Storage unit is used for described newly-built JAVA object storage to the discarded shared storage space of JAVA object of searching the handle correspondence that the unit finds.
In the embodiment of the invention technical scheme, when needs are stored newly-built JAVA object, in the handle of discarded JAVA object correspondence, search and satisfy pre-conditioned handle, then with described newly-built JAVA object storage in the shared storage space of the discarded JAVA object of the handle correspondence that finds, that is to say in the embodiment of the invention when carrying out the garbage reclamation of JAVA object, no longer be that discarded JAVA object is deleted or useful JAVA object is moved, the JAVA card just can not operated discarded JAVA object more so, therefore save the processing time and handled resource, when needs are stored newly-built JAVA object, directly search and satisfy pre-conditioned handle, the JAVA object storage that this is newly-built gets final product in the shared storage space of the discarded JAVA object of the handle correspondence that finds, can either be newly-built JAVA object memory allocated space like this, can avoid that again discarded JAVA object is carried out reclaimer operation and expend the processing time and handle resource, therefore can improve the treatment effeciency of JAVA card effectively.

Embodiment
At length set forth to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
As shown in Figure 1, be the storage means process flow diagram of JAVA object in the embodiment of the invention, its concrete treatment scheme is as follows:
Step 11 when needs are stored newly-built JAVA object, in the handle of discarded JAVA object correspondence, is searched and is satisfied pre-conditioned handle;
In the embodiment of the invention, search when satisfying pre-conditioned handle, at first need to determine discarded JAVA object, then when needs are stored newly-built JAVA object, in the handle of the discarded JAVA object correspondence of determining, search and satisfy pre-conditioned handle.Need to prove, be not that the newly-built JAVA object of each storage all needs to determine earlier before discarded JAVA object.
Wherein, can but be not limited to determine discarded JAVA object by following two kinds of methods, be specially:
First method: at first at each JAVA object, determine that this JAVA object is by the number of times of other JAVA object references, quote number of times and be zero JAVA object and can think the isolated JAVA object that can't find by other JAVA objects, therefore can be zero JAVA object with the number of times of determining, the JAVA object that is defined as discarding;
Second method: because the JAVA card is an initial point with the Applet object, therefore be basic point with all Applet objects, search its all subobjects, the subobject of subobject ..., and the like, till can not find subobject, the JAVA object that finds is formed an object tree graph, according to the object tree graph of forming, determine the JAVA object that to locate, i.e. JAVA object of not located by the object tree graph, therefore these JAVA objects are discarded JAVA object owing to can not be found by the program that with the Applet object serves as the operation initial point.
The embodiment of the invention will be distinguished useful JAVA object and discarded JAVA object in all JAVA objects of storage, to this, the embodiment of the invention proposes two kinds of implementations, is specially:
First kind of implementation, the handle of discarded JAVA object correspondence is stored in the default discarded object handle storage space, follow-up searching in described discarded object handle storage space satisfied pre-conditioned handle, this comes down in the embodiment of the invention JAVA object to be carried out the step of garbage reclamation, the embodiment of the invention is when carrying out garbage reclamation, no longer discarded JAVA object is deleted or moved useful JAVA object, but the handle of discarded JAVA object is stored in the default storage space;
Second kind of implementation, the handle of discarded JAVA object correspondence is designated discarded object handle, follow-up searching in the discarded object handle that identifies satisfied pre-conditioned handle, this comes down in the embodiment of the invention JAVA object to be carried out the step of garbage reclamation, the embodiment of the invention is when carrying out garbage reclamation, no longer discarded JAVA object is deleted or moved useful JAVA object, but the handle of discarded JAVA object is identified, be designated discarded object handle.
The JAVA card manages object based on handle, the JAVA cartoon is crossed handle can find the shared storage space of object, the handle of object is actually the index of seeking this object, identify the storage space of storing this object, comprised the position and the size of storage space, for example, the handle of certain object is 0x0001 on the JAVA card, so just can find the storage space of this object of storage by this handle of 0x0001, this moment the length of handle and JAVA stack appearance etc., the handle on the JAVA card is two bytes.
In the embodiment of the invention, when the JAVA card is confirmed memory space inadequate or have JAVA invokes system API, just can start the garbage reclamation mechanism of JAVA card, at first travel through all objects in the JAVA card, determine discarded object, the handle of the discarded object determined is all put into default discarded object handle storage space (also can be called " garbage recycling bin ") storage, and perhaps the handle of the discarded object that will determine is designated discarded object handle.
Because the embodiment of the invention is carrying out not having the discarded shared storage space of JAVA object of actual recovered when above-mentioned garbage reclamation is operated, promptly Fei Qi JAVA object does not have deleted or mobile, therefore save the processing time of JAVA card and handled resource, but because the storage space of discarded JAVA object is not retracted, therefore when newly-built JAVA object, also need the storage space of discarded JAVA object is used again, be specially:
When creating new JAVA object, the JAVA virtual machine is to the available handle of JAVA card application, and the JAVA card can be searched and satisfy pre-conditioned handle, to strive for utilizing these handle corresponding memory space again earlier in the handle of discarded JAVA object.
Wherein, search satisfy pre-conditioned handle process can but be not limited to: the size of at first determining the storage space that described newly-built JAVA object is required, at each discarded JAVA object, handle according to this discarded JAVA object correspondence, determine the size of the storage space that this discarded JAVA object is shared, in discarded JAVA object, search the discarded JAVA object of shared storage space more than or equal to the required storage space of described newly-built JAVA object, the handle of the discarded JAVA object correspondence that will find then is defined as satisfying pre-conditioned handle.
If do not find and satisfy pre-conditioned handle, then can redistribute a handle for this newly-built JAVA object, for example, handle that can the next one is available (maximal value that is current already present handle adds) is as the handle of newly-built JAVA object.
Step 12, with described newly-built JAVA object storage in the shared storage space of the discarded JAVA object of the handle correspondence that finds.
If step 11 has found and has satisfied pre-conditioned handle, then can directly this handle be distributed to this newly-built JAVA object, be about to newly-built JAVA object storage in the shared storage space of the discarded JAVA object of this handle correspondence, cover the discarded JAVA object of the original storage of this storage space;
If step 11 does not find and satisfies pre-conditioned handle, then be that newly-built JAVA object distributes new handle, on heap, distribute new storage space to give this newly-built JAVA object then.
In addition, at above-mentioned first kind of implementation (handle of discarded JAVA object correspondence is stored in the default discarded object handle storage space), if in discarded object handle storage space, found and satisfied pre-conditioned handle, with newly-built JAVA object storage behind the shared storage space of the discarded JAVA object of the handle correspondence that finds, also need in discarded object handle storage space, the handle that finds be deleted, because this handle has no longer belonged to the handle of discarded JAVA object;
At above-mentioned second kind of implementation (handle of discarded JAVA object correspondence is designated discarded object handle), satisfy pre-conditioned handle if in the discarded object handle that identifies, found, with newly-built JAVA object storage behind the shared storage space of the discarded JAVA object of the handle correspondence that finds, the handle that also needs to find is designated useful object handle, because this handle has no longer belonged to the handle of discarded JAVA object.
By above-mentioned processing procedure as can be known, in the embodiment of the invention technical scheme, when needs are stored newly-built JAVA object, in the handle of discarded JAVA object correspondence, search and satisfy pre-conditioned handle, then with described newly-built JAVA object storage in the shared storage space of the discarded JAVA object of the handle correspondence that finds, that is to say in the embodiment of the invention when carrying out the garbage reclamation of JAVA object, no longer be that discarded JAVA object is deleted or useful JAVA object is moved, the JAVA card just can not operated discarded JAVA object more so, therefore save the processing time and handled resource, when needs are stored newly-built JAVA object, directly search and satisfy pre-conditioned handle, the JAVA object storage that this is newly-built gets final product in the shared storage space of the discarded JAVA object of the handle correspondence that finds, can either be newly-built JAVA object memory allocated space like this, can avoid that again discarded JAVA object is carried out reclaimer operation and expend the processing time and handle resource, therefore can improve the treatment effeciency of JAVA card effectively.
