Enclosing class:

ByteArrayClassLoader

public static class ByteArrayClassLoader.ChildFirst
extends ByteArrayClassLoader

A ByteArrayClassLoader which applies child-first semantics for the given type definitions.

Important: Package definitions remain their parent-first semantics as loaded package definitions do not expose their class loaders. Also, it is not possible to make this class or its subclass parallel-capable as the loading strategy is overridden.
