Class ClassVisitorFactory<T>

java.lang.Object

net.bytebuddy.asm.ClassVisitorFactory<T>

Type Parameters:

T - The type of the mapped class visitor.

@Enhance
public abstract class ClassVisitorFactory<T>
extends Object

A factory for wrapping a ClassVisitor in Byte Buddy's package namespace to a ClassVisitor in any other namespace. Note that this API does not allow for the passing of Attributes. which must be filtered or propagated past this translation. If the supplied visitors do not declare a method that Byte Buddy's version of ASM is aware of, an UnsupportedOperationException is thrown.
