Method Detail

constructing

void constructing(java.lang.reflect.Constructor ctor,
                  java.lang.Object[] args)

This method is called right before the constructor is invoked.

Parameters:

ctor - the constructor to be called.

args - the arguments passed to the constructor.

constructed

Parameters:

ctor - the constructor.

args - the arguments passed to the constructor.

instance - the object created by the constructor.

duration - excactly how long the constructor execution takes. (in milliseconds)

constructionFailed

void constructionFailed(java.lang.reflect.Constructor ctor,
                        java.lang.Object[] args,
                        java.lang.Throwable e,

This method is called after the constructor failed.

Parameters:

ctor - the constructor.

args - the arguments passed to the constructor.

e - the exception thrown out of the constructor.
