  +--org.apache.bcel.verifier.VerifierFactory

public class VerifierFactory

extends java.lang.Object

This class produces instances of the Verifier class. Its purpose is to make sure that they are singleton instances with respect to the class name they operate on. That means, for every class (represented by a unique fully qualified class name) there is exactly one Verifier.

Method Detail

getVerifier

public static Verifier getVerifier(java.lang.String fully_qualified_classname)

Returns the (only) verifier responsible for the class with the given name. Possibly a new Verifier object is transparently created.

Returns:

the (only) verifier responsible for the class with the given name.

getVerifiers

public static Verifier[] getVerifiers()

Returns all Verifier instances created so far. This is useful when a Verifier recursively lets the VerifierFactory create other Verifier instances and if you want to verify the transitive hull of referenced class files.

attach

public static void attach(VerifierFactoryObserver o)

Adds the VerifierFactoryObserver o to the list of observers.

detach

public static void detach(VerifierFactoryObserver o)

Removes the VerifierFactoryObserver o from the list of observers.
