Detailed Description

template<class T>
class dueca::StreamReader< T >

This is a facilitator for reading stream data.

By creating a "StreamReader", the access token is used to gain access to the data in the channel. When at the end of scope the StreamReader is destroyed, the access is released again.

Constructor & Destructor Documentation

StreamReader()

template<class T >

dueca::StreamReader< T >::StreamReader ( StreamChannelReadToken< T > & token, const TimeSpec & ts )

inline

Constructor.

Gains access to the channel for which the token was made.

Parameters

token	Read access token.
ts	Time specification.

~StreamReader()

template<class T >

dueca::StreamReader< T >::~StreamReader ( )

inline

Destructor.

Releases the access again with a token.

Member Function Documentation

ok()

template<class T >

bool dueca::StreamReader< T >::ok ( )

inline

Check that the stream reading is OK.

Only applicable in code without exceptions.
