Embodiment Construction

[0029] The core idea of ​​the present invention is: set a storage unit in advance; extract the basic information of each operation in various operation sequences, and record the extracted information in the preset storage unit, by analyzing the rules of the elements in the storage unit, To determine whether there is an infinite loop.

[0030] The technical solution of the present invention will be described in detail below by taking the message or function passing through the relational bus as an example.

[0031] In this embodiment, the method for detecting an object reference infinite loop is: queuing related messages passing through the relational bus, and monitoring the queued messages, so as to realize the detection of an infinite loop occurring during the object reference process. After a referenced object changes, those objects that refer to the referenced object should be notified, so that these objects can make some response processing after the referenced object chan...

Abstract

The method of detecting dead circulation includes presetting memory units for recording basic operation information; recording the basic information of each operation in the memory units; judging whether to exist dead circulation based on the regulation of the elements recorded in the current memory unit; and terminating the operation corresponding to the dead circulation if so, and or else returning to the step of recording the basic information of each operation in the memory units. The method of the present invention may be used in detecting target calling, function calling, operating sequence and other maybe dead circulation effectively, and this can avoid effectively the crash caused by dead circulation. The method is reliable and practical.

Description

technical field [0001] The invention relates to object reference management technology, in particular to a method for detecting an infinite loop. Background technique [0002] In the Chinese patent application whose publication number is 1503147, the present inventor once proposed a method for processing object relationships in a database. This method is a management technology based on object references of a relational bus. It can be attributed to a reference relationship. Therefore, while there is an object oA referencing object oB, there may also be an object oB referencing object oA; or an object oA refers to object oB, object oB refers to object oC, and object oC refers to object oA In this case, the above references are called circular references. In the process of object circular reference, usually, the change of oA will cause the change of oB, and the change of oB will cause the change of oA, and then the change of oA will cause the change of oB, which may lead to a...
