public Class VerifierFactory

extends Object
Class Inheritance
Imports
java.util.HashMap, .List, .Map, .Vector
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.

public static Verifier getVerifier(final String fullyQualifiedClassName)

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

Returns:Verifier

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

getVerifiersback to summary
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.

notifyback to summary
private static void notify(final String fullyQualifiedClassName)

Notifies the observers of a newly generated Verifier.
