Package net.sf.cglib.core

## 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.

### Field Summary

Fields
`static DefaultNamingPolicy` `INSTANCE`

### Constructor Summary

Constructors
`DefaultNamingPolicy()`

### Method Summary

All Methods Instance Methods Concrete Methods
`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.
`int` `hashCode()`

### Field Detail

#### INSTANCE

    public static final DefaultNamingPolicy INSTANCE

### Constructor Detail

#### DefaultNamingPolicy

    public DefaultNamingPolicy()

### Method Detail

#### 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

    public boolean equals​(java.lang.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 `java.lang.Object`
