void FilterChain::clear ( void )

inherited

Removes all filters from the chain.

Definition at line 82 of file Filter.cpp.

References clear().

bool FilterChain::containsFilter ( Filter * filter )

inherited

Returns true if the chain contains filter.

Definition at line 60 of file Filter.cpp.

Filter::HotSpot * FilterChain::hotSpotAt	(	int	line,
		int	column
	)		const

inherited

Returns the first hotspot which occurs at line, column or 0 if no hotspot was found.

QList<Filter::HotSpot> FilterChain::hotSpotsAtLine ( int line ) const

inherited

Returns a list of all hotspots at the given line in all the chain's filters.

void FilterChain::process ( )

inherited

Processes each filter in the chain.

void FilterChain::removeFilter ( Filter * filter )

inherited

Removes a filter from the chain.

The chain will no longer delete the filter when destroyed

Definition at line 56 of file Filter.cpp.

void FilterChain::reset ( void )

inherited

Resets each filter in the chain.

Definition at line 64 of file Filter.cpp.

void FilterChain::setBuffer	(	const QString *	buffer,
		const QList< int > *	linePositions
	)

inherited

Sets the buffer for each filter in the chain to process.

Referenced by setImage().

void TerminalImageFilterChain::setImage	(	const Character *const	image,
		int	lines,
		int	columns,
		const QVector< LineProperty > &	lineProperties
	)

Set the current terminal image to image.

Parameters

image	The terminal image
lines	The number of lines in the terminal image
columns	The number of columns in the terminal image
