`boolean` | `isCase(Object switchValue)` Special 'Case' implementation for Class, which allows testing for a certain class in a switch statement.
`MetaClass` | `metaClass(Closure closure)` Sets/updates the metaclass for a given class to a closure.
`void` | `mixin(List categoryClasses)` Extend class globally with category methods.
`void` | `mixin(Class categoryClass)` Extend class globally with category methods.
`void` | `mixin(Class[] categoryClass)` Extend class globally with category methods.
`Object` | `newInstance()` Convenience method to dynamically create a new instance of this class.
`Object` | `newInstance(Object[] args)` Helper to construct a new instance from the given arguments.
`void` | `setMetaClass(MetaClass metaClass)` Sets the metaclass for a given class.

Method Detail

### getMetaClass

    public MetaClass getMetaClass()

  Adds a "metaClass" property to all class objects so you can use the syntax `String.metaClass.myMethod = { println "foo" }`

Returns:
  An MetaClass instance

Since:
  1.5.0

### isCase

    public boolean isCase(Object switchValue)

  Special 'Case' implementation for Class, which allows testing for a certain class in a switch statement. For example:

      switch( obj ) {
        case List :
          // obj is a list
          break;
        case Set :
          // etc
      }

Parameters:
  `switchValue` - the switch value.

Returns:
  true if the switchValue is deemed to be assignable from the given class

Since:
  1.0

### metaClass

    public MetaClass metaClass(Closure closure)

  Sets/updates the metaclass for a given class to a closure.

Parameters:
  `closure` - the closure representing the new metaclass.

Returns:
  the new metaclass value

Since:
  1.6.0

### mixin

    public void mixin(List categoryClasses)

  Extend class globally with category methods. All methods for given class and all super classes will be added to the class.

Parameters:
  `categoryClasses` - a category classes to use.

Since:
  1.6.0

### mixin

    public void mixin(Class categoryClass)

  Extend class globally with category methods.

Parameters:
  `categoryClass` - a category class to use.

Since:
  1.6.0

### mixin

    public void mixin(Class[] categoryClass)

  Extend class globally with category methods.

Parameters:
  `categoryClass` - a category class to use.

Since:
  1.6.0

### newInstance

    public Object newInstance()

  Convenience method to dynamically create a new instance of this class. Calls the default constructor.

Returns:
  a new instance of this class

Since:
  1.0

### newInstance

    public Object newInstance(Object[] args)

  Helper to construct a new instance from the given arguments. The constructor is called based on the number and types in the args array. Use `newInstance(null)` or simply `newInstance()` for the default (no-arg) constructor.

Parameters:
  `args` - the constructor arguments.

Returns:
  a new instance of this class.

Since:
  1.0

### setMetaClass

    public void setMetaClass(MetaClass metaClass)

  Sets the metaclass for a given class.

Parameters:
  `metaClass` - the new MetaClass.

Since:
  1.6.0
