Method Detail

scopeStart

public void scopeStart(BlockDefinition block)

Notify a new scope has started; invoked by ProcedureManager's scoping support when a new scope is started.

Notification will be performed only on the start of a top-level block (external program, procedure, function or trigger).

No default unnamed pool will be created. An unnamed pool must be explicitly created to be used.

Parameters:

block - The explicit block definition which required this notification.

scopeFinished

public void scopeFinished(java.lang.Object oThis,
                          boolean external,
                          boolean persistent)

Notify a scope has finished; invoked by ProcedureManager's scoping support when a scope is finished.

This will delete the created non-persistent pools, but only if this is not a notification of an external procedure which was ran persistent.

Notification will be performed only on the end of a top-level block (external program, procedure, function or trigger).

Parameters:

oThis - Current THIS-PROCEDURE handle.

external - Flag indicating that this is an external procedure.

persistent - Flag indicating that this external procedure is ran persistent.
