Constructor & Destructor Documentation

virtual casa::IChangeDetector::~IChangeDetector ( )

protectedvirtual

a virtual destructor to make the compiler happy

virtual casacore::Bool casa::IChangeDetector::changed	(	const VisBuffer &	vb,
		casacore::Int	row
	)		const

pure virtual

return true if a change occurs in the given row since the last call of update

casacore::Bool casa::IChangeDetector::changed ( const VisBuffer & vb ) const

some derived methods, which use the abstract virtual function changed(vb,row)

return true if a change occurs somewhere in the buffer

casacore::Bool casa::IChangeDetector::changedBuffer	(	const VisBuffer &	vb,
		casacore::Int	row1,
		casacore::Int &	row2
	)		const

return true if a change occurs somewhere in the buffer starting from row1 up to row2 (row2=-1 means up to the end of the buffer).

The row number, where the change occurs is returned in the row2 parameter

virtual void casa::IChangeDetector::reset ( )

pure virtual

reset to the state which exists just after construction

virtual void casa::IChangeDetector::update	(	const VisBuffer &	vb,
		casacore::Int	row
	)

pure virtual

start looking for a change from the given row of the VisBuffer
