Detailed Description

Duplicate all data passed by the stream operator to two output streams.

Can be used as replacement for any OutputStream – for example, forwarding the DBG output simultaneously to screen (TextStream) and serial console (SerialStream).

By using template programming, two generic methods are sufficient (which simply forward the input to both).

Constructor & Destructor Documentation

CopyStream()

CopyStream::CopyStream ( OutputStream * first, OutputStream * second )

inline

Constructor.

Parameters

first	First recipient for output passed to this object
second	Second recipient for output passed to this object

Member Function Documentation

operator<<() [1/2]

template<typename T>

CopyStream & CopyStream::operator<< ( T value )

inline

Generic stream operator for any data type.

Forwards all input to both recipients.

Uses template meta programming for a generic & short solution

Template Parameters

T	Type of data to be forwarded

Parameters

value

data to be forwarded

Returns

Reference to the CopyStream object allowing concatenation of operators

Optional

Implement method

operator<<() [2/2]

template<typename T>

CopyStream & CopyStream::operator<< ( T &(* f )(T &) )

inline

Deal with [OutputStream] manipulator functions.

Template Parameters

T	Manipulator type

Parameters

f	pointer to manipulator function

Returns

Reference to the CopyStream object allowing concatenation of operators
