Method Detail

isConstrained

public boolean isConstrained(String internedClassname,

                      throws ClassBytesNotFoundException

Verifies if the Constrained interface is implemented by the class that is defined by the bytes that are provided.

Parameters:

internedClassname - the class name as the previously interned string

bytes - the array of bytes that defines the class that needs to be analyzed
