org.jboss.verifier.strategy
Class AbstractVerifier

All Implemented Interfaces:
org.gjt.lindfors.pattern.Strategy, VerificationStrategy
Direct Known Subclasses:

public abstract class AbstractVerifier
extends Object
implements VerificationStrategy

Abstract superclass for verifiers containing a bunch of useful methods.

Since:
JDK 1.3
Version:
$Revision: 1.43 $
Author:
Juha Lindfors, Aaron Mulder (ammulder@alumni.princeton.edu), Vinay Menon (menonv@cpw.co.uk), Andreas Schaefer, Luke Taylor, Jay Walters

20020210: luke

  • Changed hasRemoteReturnType() to use isAssignableFrom() rather than just compare strings. See Bug 489554 (sub-classed remote return types should be OK)

20020404: jwalters

  • Added new helper methods for Local home and interface matching pre-existing methods for Remote home and interface.

20020404: luke

  • Changed hasDefaultConstructor to use reflection rather than calling newInstance. The latter won't work with abstract classes.
