Method Summary

Modifier and Type	Method	Description
boolean	canExecute(long step)	Can this notification be executed? That is, are all of it's dependencies satisfied.
boolean	isTerminal()	Terminal notifications guarantee that they will not queue additional notifications or mutate data structures that should result in additional notifications.
boolean	mustExecuteWithLtmLock()	If a terminal notification must be executed on the main LTM thread, it must override this method, so that the notification is not executed on the refresh pool.

Method Details

isTerminal

boolean isTerminal()

Terminal notifications guarantee that they will not queue additional notifications or mutate data structures that should result in additional notifications. They are in turn guaranteed to be called after all non-terminal notifications for a given cycle through the notification queue.

Returns:

True iff this notification is terminal.

mustExecuteWithLtmLock

boolean mustExecuteWithLtmLock()

If a terminal notification must be executed on the main LTM thread, it must override this method, so that the notification is not executed on the refresh pool. It is an error to return true if this notification is not terminal

Returns:

true if this notification must be executed directly under the protection of the LTM lock

canExecute

boolean canExecute(long step)

Can this notification be executed? That is, are all of it's dependencies satisfied.

Parameters:

step - The step for which we are testing satisfaction

Returns:

true if this notification can be executed, false if it has unmet dependencies
