    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 ( 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

    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
    TType of data to be forwarded
    Parameters
    valuedata to be forwarded
    Returns
    Reference to the CopyStream object allowing concatenation of operators
    Optional:
    Implement method
    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
