Object cern::gp::nodes::impl::CacheableIndexedPropertySupport::getIndexedValue int  index  )  throws IllegalAccessException, IllegalArgumentException, InvocationTargetException [inline]
 

overrides getIndexedValue, and caches the value

PropertyEditor cern::gp::nodes::impl::CacheableIndexedPropertySupport::getPropertyEditor  )  [inline]
 

Returns an instance of property editor for this property. The implementation reconizes a special type of PropertyEditor that implements cern.gp.beans.BeanDependentPropertyEditor and invoke their initialization method.

Returns:
the property editor or null if there should not be any editor.
