Detailed Description

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

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

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

Constructor & Destructor Documentation

AnyDataReader()

template<typename T >

dds::sub::AnyDataReader::AnyDataReader ( const dds::sub::DataReader< T > &  reader )

inline

Create an AnyDataReader that represents a generic, untyped DataReader.

Template Parameters

T	The type of the DataReader that this AnyDataReader is being created from

Parameters

reader

The typed DataReader that this AnyDataReader will represent
