Class SimpleInstantiatingReflector

java.lang.Object
  net.sf.morph.reflect.reflectors.BaseReflector
      net.sf.morph.reflect.reflectors.SimpleInstantiatingReflector

All Implemented Interfaces:

net.sf.composite.Component, DecoratedReflector, InstantiatingReflector, Reflector

public class SimpleInstantiatingReflector
extends BaseReflector
implements InstantiatingReflector

A basic instantiating reflector that allows an arbitrary number of requested class types to be mapped to instantiated types. The default instance of this class can instantiate common interfaces such as Calendar and CharSequence.

Method Detail

getReflectableClassesImpl

protected java.lang.Class[] getReflectableClassesImpl()
                                               throws java.lang.Exception

Implementation of Reflector.getReflectableClasses().

Specified by:

getReflectableClassesImpl in class BaseReflector

Throws:

java.lang.Exception

See Also:

BaseReflector.getReflectableClassesImpl()

newInstanceImpl

protected java.lang.Object newInstanceImpl(java.lang.Class requestedType,
