Method Detail

cleanup

public void cleanup(Execution exec,
                    Execution parent,
                    java.util.List errs)
             throws java.lang.Exception

Description copied from interface: ExecutionCleanup

called when an execution is about to be destroyed.

If this method throws an exception, the stack trace will be logged, and the error message will be displayed at the client.

When this method is invoked, the execution is still activated, so you can create components here.

Specified by:

cleanup in interface ExecutionCleanup

Parameters:

exec - the exection to clean up.

parent - the previous execution, or null if no previous at all

errs - a list of exceptions (java.lang.Throwable) if any exception occured before this method is called, or null if no exeption at all. Note: you can manipulate the list directly to add or clean up exceptions. For example, if exceptions are fixed correctly, you can call errs.clear() such that no error message will be displayed at the client.

Throws:

java.lang.Exception
