The invention is illustrated below with reference to specific examples:
fig. 2 is a flowchart of operations of clearing a cache according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
step 201: opening the device;
step 202, setting an expiration time; the scheme in the embodiment can be integrated on a network management system (or can be detected as network management), can set the expiration time, and can also process according to the default time of the network management, such as 6 hours;
step 203: analyzing the time of the application function interface from opening to closing; the application program interface is opened and closed, and the functional framework can be recorded by the onClicked and onClosed keywords respectively; analyzing the current memory occupation condition of each application;
step 204: analyzing the current window activation state of the application; analyzing the activation state of the network management application interface window, if the activation mark belongs to Active, if the current window is Closed, marking as Closed;
step 205: generating a data structure according to the key information; and associating according to the current operation object, the name of the application function, the opening-to-closing time of the interface and the window activation state and according to the tree structure (regardless of the tree structure). Setting priorities (EMS, group, NE, rack, shelf, board and TP) according to parent and child nodes, and associating the priorities into a large tree data structure;
step 206: packaging the data structure into a command which can be identified by the network management; for example, the current use of the network manager is F interface command, ASN1 object structure, and the message of the structure is used to inform the network manager to process; the interface command structure is composed of a plurality of attribute fields, and comprises network elements, a single board, ports, application function data and other structural objects associated in step 205, and each object is identified by ID as a unique key word of the whole network; the command is sent to the server by the client, and the server device (integrated in the network management server) is informed to execute the command;
step 207: the network management analyzes the command; finding out which function is specific according to the attribute of the command and the attribute of the functional data of the interface; after the function is found, the time from opening to closing of the function interface is compared with the preset timeout, and if the interface is not closed, the time attribute is set to be infinite;
step 208: decomposing the command into units;
step 209: judging whether the period is exceeded;
step 210: not expiring, skipping the cell;
step 211: judging whether to activate;
step 212: the period is expired and the window is activated, and the unit thread is set to be dormant; if it is expired, and the window is active. Then the present solution removes the work thread for which the function is enabled from the thread pool and sets it to sleep. After the thread is dormant, the memory occupied by the thread is released, and the memory is redistributed when the thread is started;
step 213: when the time is out and the window is closed, the network manager clears the cache according to the unit operation object and releases the memory; if it is expired, and the window is in a closed state. In the function range, the scheme firstly searches the port object list at the lowest layer, removes the list and releases the memory occupied by the data. Assigning the list reference to null, releasing the memory occupied by the list, and calling a delete sql statement to delete the list data if the data is also stored in the database;
and searching upwards step by step to find the list of the single board and the network element object. If the method in step 210 deletes the object save list, release the memory;
and finally, searching an application module function self data list (corresponding to the application self data list), clearing the list clear, and assigning the reference to null. The function also has a listener object, and the present invention drops the listener object to which the function relates. The function also has an interface UI object, the invention executes the destroy operation on the UI object, destroys the UI object and releases the memory;
if the application module data is incomplete, the data cannot be practically applied. Then the invention carries out the deletion operation of the residual data, according to the main key of the database table, the delete sql statement is called, the corresponding residual data is deleted, and the occupied memory is released;
step 214: the cache flush is successful.
