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" }

isCase

public boolean isCase(Object switchValue)
 
Special 'Case' implementation for Class, which allows testing for a certain class in a switch statement. For example:

    // obj is a list
    break;
  case Set :
    // etc
}
Parameters:
switchValue - the switch value.

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:

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.
