Detailed Description

DtMessageFilter is a base class for filters applied to DtFilteredTcpForwarder.

DtMessageFilter and its derived classes process incoming messages and return a list of connections. The default DtMessageFilter returns an unmodified list.

Constructor & Destructor Documentation

DtMessageFilter::DtMessageFilter ( const char * name ) [inline]

Default Ctor ( created with empty list of filtered messages )

DtMessageFilter::DtMessageFilter	(	const char *	name,
		const std::set< DtRtiMsgKind > &	filteredKinds
	)		`[inline]`

Ctor taking a set of filtered message kinds.

DtMessageFilter::~DtMessageFilter ( ) [inline, virtual]

Default Dtor.
