Class 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.

    • Method Summary

      All Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      boolean equals​(java.lang.Object o)
      The NamingPolicy in use does not currently, but may in the future, affect the caching of classes generated by AbstractClassGenerator, so this is a reminder that you should correctly implement equals and hashCode to avoid generating too many classes.
      java.lang.String getClassName​(java.lang.String prefix, java.lang.String source, java.lang.Object key, Predicate names)
      Choose a name for a generated class.
      protected java.lang.String getTag()
      Returns a string which is incorporated into every generated class name.

      • getClassName

        public java.lang.String getClassName​(java.lang.String prefix,
                                             java.lang.String source,
                                             java.lang.Object key,
                                             Predicate names)
        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
      • getTag

        protected java.lang.String getTag()
        Returns a string which is incorporated into every generated class name. By default returns "ByCGLIB"
      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.lang.Object
      • equals
