Class AvoidDuplicatePatchingCBP

java.lang.Object

org.zeroturnaround.javarebel.integration.support.JavassistClassBytecodeProcessor

org.zeroturnaround.javarebel.integration.support.AvoidDuplicatePatchingCBP

All Implemented Interfaces:

org.zeroturnaround.javarebel.ClassBytecodeProcessor

public class AvoidDuplicatePatchingCBP
extends JavassistClassBytecodeProcessor

A CBP that avoids patching a given class when it has already been patched. The mechanism for checking this is to add a field to the class with a comma-separated list of CBP names that have been applied to the class and to check this list for a match before running the cbp.

getCachingPolicy

protected JavassistClassBytecodeProcessor.CachingPolicy getCachingPolicy()

Description copied from class: JavassistClassBytecodeProcessor

Returns the caching policy used by this processor. If a processor uses a caching policy that isn't equal to NEVER, then its transformations may be cached between runs. A processor then needs to make sure that its process method does not have any side effects. Also, the processing of a tagless processor may only depend on the arguments (the class loader, the name of the class and the bytes) and on rebel.* configuration properties. In case of any other dependencies, a tag should be used to identify the processing configuration. This method returns ALWAYS if not overridden.

Overrides:
