Detailed Description

template<class T>
struct JLANG::JAbstractAccessibleObjectWriter< T >

Abstract interface for object writing with named access.

This class implements the JAccessibleObjectOutput interface by transferring the interface methods to a helper object via a single interface method getHelper().
