Detailed Description

class inherits from std::basic_streambuf and is able to transform a stream, like std::cout or std::cerr, into emitted signals

Constructor & Destructor Documentation

QDebugStream()

ito::QDebugStream::QDebugStream	(	std::ostream &	stream,
		ito::tStreamMessageType	type )

constructor

initializes this instance and stores actual content of stream in m_old_buf

Parameters

stream	Stream of type std::ostream which should be observed
type	message type of enumeration tMsgType which corresponds to the stream
lineBreak	string representation of line break, default:

Returns

~QDebugStream()

ito::QDebugStream::~QDebugStream

(

)

destructor

destroys this instance and the stream observation and emits remaining string in the buffer. Restores m_old_buf to the stream.

Member Function Documentation

flushStream

void ito::QDebugStream::flushStream ( QString , ito::tStreamMessageType  )

signal

signal emits a string which appeared in the observed stream together with indicating the corresponding message type

overflow()

std::basic_streambuf< char >::int_type ito::QDebugStream::overflow ( int_type v )

protectedvirtual

this method overwrites a corresponding method in basic_streambuf class and is invoked, if buffer risks to overflow

m_string

std::string ito::QDebugStream::m_string

private

buffer string, containing parts of the stream which have not been emitted yet

msg_type

ito::tStreamMessageType ito::QDebugStream::msg_type

private

message type of enumeration ito::tStreamMessageType
