Class TemporaryBuffer.NoUndoValidator

java.lang.Object

com.goldencode.p2j.persist.TemporaryBuffer.NoUndoValidator

All Implemented Interfaces:

Finalizable

Enclosing class:

TemporaryBuffer

private class TemporaryBuffer.NoUndoValidator
extends java.lang.Object
implements Finalizable

An object of this class is registered at all blocks within a no-undo buffer's scope, except internal procedures (TODO: further testing is needed to verify that this is correct). Upon each iteration, retry, and exit (finished) event of one of those blocks, it performs a non-destructive validation (i.e., validation which reports any error, but does not alter control flow).
