NullStream Class Reference

Ignore all data passed by the stream operator. More...

#include <debug/nullstream.h>

Public Member Functions
	NullStream ()
	Empty default constructor.
template<typename T >
NullStream &	operator<< (T value)
	Generic stream operator for any data type.

Private Member Functions
template<typename T >
auto	check (T v, OutputStream *p=nullptr) -> decltype(*p<< v, void())
	Check if type is supported by output stream.

Detailed Description

Ignore all data passed by the stream operator.

Can be used instead of the OutputStream if (for debugging reasons) all output should be ignored, e.g. for DBG_VERBOSE

By using template programming, a single generic methods is sufficient (which simply discard everything).

Constructor & Destructor Documentation

NullStream()

NullStream::NullStream ( )

inline

Empty default constructor.

Member Function Documentation

check()

template<typename T >

auto NullStream::check ( T  v, OutputStream *  p = nullptr  ) -> decltype(*p << v, void())

inlineprivate

Check if type is supported by output stream.

operator<<()

template<typename T >

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

inline

Generic stream operator for any data type.

Uses template meta programming for a generic & short solution

Template Parameters

T	Type of data to ignore

Parameters

value

data to be ignore

Returns

Reference to the NullStream object allowing concatenation of operators
