Class ConstructorProxyTransformation

java.lang.Object
  org.sourceforge.jemm.weaver.transformation.AbstractClassTransformation
      org.sourceforge.jemm.weaver.transformation.ConstructorProxyTransformation

All Implemented Interfaces:

Transformation

public class ConstructorProxyTransformation
extends AbstractClassTransformation

Proxies the constructors creation with a begin and end call. Produces code similar to: super(); try { ConstructorLifecycle.preConstructor(???.class.getName()); super(); ConstructorLifecycle.beginConstructor(this); //original code ConstructorLifecycle.endConstructor(this); } catch(Throwable t) { ConstructorLifecycle.failedConstructor(this); throw t; }
