lookupMethodSignatureVisitor

public MethodSignatureVisitor lookupMethodSignatureVisitor(int access,
                                                           java.lang.String name,

Returns method signature for some method. If signature is not found, returns null. Founded signatures means that those method can be proxyfied.

isMarkedForProxy

public boolean isMarkedForProxy(MethodSignatureVisitor msgin)

Returns true if method is marked for proxy.

getAnnotations

public AnnotationInfo[] getAnnotations()

Description copied from interface: ClassInfo

Returns annotation information or null if target class has no annotations.

Specified by:

getAnnotations in interface ClassInfo

visit
