Detailed Description

template<typename T>
class RDB_shared_data< T >

Shared data for RDBHilbert threads.

Constructor & Destructor Documentation

template<typename T>

RDB_shared_data< T >::RDB_shared_data ( )

inline

In case of ZXa or ZaX, a pointer to a collection of global input vectors.

In case of ZXa or ZaX, a pointer to a collection of output vectors. Pointer to a local output vector set (in case of ZXa or ZaX). Base constructor. Will initialise all to invalid values or NULL.
