Class VerifierFactory
java.lang.Object
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.

hashMap
private static Map hashMap
The HashMap that holds the data about the already-constructed Verifier instances.
observers
private static List observers
The VerifierFactoryObserver instances that observe the VerifierFactory.
VerifierFactory
private VerifierFactory()
The VerifierFactory is not instantiable.
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.
getVerifier
public static Verifier getVerifier(String fully_qualified_classname)
Returns the (only) verifier responsible for the class with the given name.
Possibly a new Verifier object is transparently created.
- 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.
notify
private static void notify(String fully_qualified_classname)
Notifies the observers of a newly generated Verifier.
