Member Function Documentation

virtual bool DtRtiMtdNull::get ( ) const

virtual

Find the first null metadata block within the message metadata.

Since this metadata is null, there is nothing to get and this method only serves to confirm that the entry exists. Return: found entry?

DtRtiMtdNull& DtRtiMtdNull::operator= ( const DtRtiMtdNull &  )

private

Assignment Operator Not Implemented – Assignment Not Allowed!

virtual bool DtRtiMtdNull::set ( )

virtual

Reserves space in RTI message buffer (if necessary) for a null metadata block which consists entirely of a metadata header.

Returns true if successful, false otherwise.
