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
firstFirst recipient for output passed to this object
secondSecond recipient for output passed to this object

Member Function Documentation

◆ operator<<() [1/2]

template<typename T >
CopyStream & CopyStream::operator<< ( 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
TType of data to be forwarded
Parameters
valuedata 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 &(*)(T &)  f)
inline

Deal with [OutputStream] manipulator functions.

Template Parameters
TManipulator type
Parameters
fpointer to manipulator function
Returns
Reference to the CopyStream object allowing concatenation of operators
