Class DefaultNamingPolicy

java.lang.Object
  net.sf.cglib.core.DefaultNamingPolicy

All Implemented Interfaces:

NamingPolicy

public class DefaultNamingPolicy

extends java.lang.Object

implements NamingPolicy

The default policy used by AbstractClassGenerator. Generates names such as

net.sf.cglib.Foo$$EnhancerByCGLIB$$38272841

This is composed of a prefix based on the name of the superclass, a fixed string incorporating the CGLIB class responsible for generation, and a hashcode derived from the parameters used to create the object. If the same name has been previously been used in the same ClassLoader, a suffix is added to ensure uniqueness.

getClassName

                                     java.lang.String source,
                                     java.lang.Object key,

Description copied from interface: NamingPolicy

Choose a name for a generated class.

Specified by:

getClassName in interface NamingPolicy

Parameters:

prefix - a dotted-name chosen by the generating class (possibly to put the generated class in a particular package)

source - the fully-qualified class name of the generating class (for example "net.sf.cglib.Enhancer")

key - A key object representing the state of the parameters; for caching to work properly, equal keys should result in the same generated class name. The default policy incorporates key.hashCode() into the class name.

names - a predicate that returns true if the given classname has already been used in the same ClassLoader.

Returns:

the fully-qualified class name
