Class ThreadAssocStore

java.lang.Object

hudson.plugins.project_inheritance.util.ThreadAssocStore

public class ThreadAssocStore
extends Object

This singleton class is used to associated arbitrary objects with the current thread.

It is a singleton to ensure static access from all corners of the application. It can be used as a crude way to communicate across methods in the same call stack.

Simply think of it as a way to store thread-global object references. The content will be removed after the thread ends. If you need earlier release, just overwrite the values with a null.

Do note that this class will purge the map from dead threads every minutes as long as threads are being added. This is done to prevent the held Threads from not being garbage-collected.
