Class DefaultNamingPolicy

java.lang.Object
org.springframework.cglib.core.DefaultNamingPolicy
All Implemented Interfaces:
NamingPolicy

public class DefaultNamingPolicy extends Object implements NamingPolicy
The default policy used by AbstractClassGenerator. Generates names such as

org.springframework.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

      public String getClassName(String prefix, String source, 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 "org.springframework.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 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 Object
    • equals

      public boolean equals(Object o)
      Description copied from interface: NamingPolicy
      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.
      Specified by:
      equals in interface NamingPolicy
      Overrides:
      equals in class Object
