Detailed Description

<<reference-type>> This class provides an non-template holder for representing a DataWriter of any type

This class is useful for code that uses DataWriters of different types. It provides access to type-independent DataWriter functions.

An AnyDataWriter is always created from a typed DataWriter, increasing its reference count. The member function get() allows getting the typed DataWriter back.

Constructor & Destructor Documentation

template<typename T >

dds::pub::AnyDataWriter::AnyDataWriter ( const dds::pub::DataWriter< T > &  dw )

inline

Create an AnyDataWriter that represents a generic, untyped DataWriter.

Template Parameters
