Method Detail

apply

public final void apply(ResultSet rs)

Applys changes in the "a" object to the "b" object in the result set. i.e. "b" is the master object, "a" contains changes.

fireEvents

public DBObjectChange[] fireEvents()

fireLazyChangeEvent

public static DBObjectChange fireLazyChangeEvent(SchemaObject obj,
                                                 SchemaObject copyOfOriginal)

Creates and fires a DBObjectChange event for the given object. A copy of its original state is given, on the understanding that the object itself is currently in an unbuilt state (having been "reset" as the result of an update or timestamp change). The event will lazily load the object if a diff is required.

Parameters:

obj - the object to fire the event on

updateCopy - a copy of the last know state of the object.
