Class Task

java.lang.Object
  oracle.jdevimpl.audit.util.Task

public abstract class Task
extends java.lang.Object

An abstract task executed by a SwingExecutor. A concrete task must override its execute(java.lang.Object) method to execute itself, and must override its commit(java.lang.Object) method to commit its work.

For better responsiveness, a concrete task should also override its cancelExecute() and/or cancelCommit() methods if execute or commit are potentially long running and can be cancelled.

Finally, a task which holds resources between executions should override its close() method to release those resources.
