Method Details

isConstrained

public boolean isConstrained(String internedClassname,
 byte[] bytes)
                      throws ClassBytesNotFoundException

Parameters:

internedClassname - the class name as the previously interned string

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