Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0030] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0031] Such as figure 1 As shown, the present invention provides a method for automatically managing memory cache objects, comprising the following steps:

[0032] For an object placed in the memory cache, the object is placed in the strong reference queue and the weak reference queue at the same time,

[0033] When accessing the object, first look for whether the object exists in the strong reference queue, if yes, return, if not, continue to search for the object in the weak reference queue,

[0034] If the object is found in the weak reference queue, add the object from the ...

Abstract

The invention discloses an automatic management method of an object cached in a memory. The automatic management method comprises the following steps: simultaneously putting the object, which is put into a memory cache, into a strong reference queue and a weak reference queue; when accessing the object, searching whether the object exists in the strong reference queue first, and if the object exists in the strong reference queue, returning; if the object does not exist in the strong reference queue, continuously searching whether the object exists in the weak reference queue; if the object is searched in the weak reference queue, adding the object from the weak reference queue into the strong reference queue; and if the object is not searched in the weak reference queue, establishing the object, and caching the object into the strong reference queue. According to the method disclosed by the invention, only one object exists in the memory within the same time, so that re-establishment of the object is avoided. The invention provides an automatic recycling mechanism of the memory; and no object is actively released from outside. By means of monitoring the weak reference queue, the object with memory leak can be found.

Description

technical field [0001] The invention belongs to the technical field of automatic management and relates to a method for automatic management of memory cache objects. Background technique [0002] Memory leak (memory leak) means that some objects are not recycled at the end of their life cycle and still occupy memory. Memory leak is a relatively common problem in the application development process. A serious leak will consume a large amount of memory, which will greatly affect the experience of the application itself, and even trigger OOM (memory overflow, that is, the memory usage exceeds the maximum allocated value) and other abnormal behavior. For languages ​​based on object recycling, singleton objects generally reside in memory, which sometimes leads to memory leaks. Contents of the invention [0003] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages as will be described hereinafter...
