Returns the hotspot which covers the given line and column, or 0 if no hotspot covers that area

	)

protectedvirtual

Called when a match for the regular expression is encountered.

Subclasses should reimplement this to return custom hotspot types

Reimplemented from RegExpFilter.

Definition at line 416 of file Filter.cpp.

void RegExpFilter::process ( )

virtualinherited

Reimplemented to search the filter's text buffer for text matching regExp()

If regexp matches the empty string, then process() will return immediately without finding results.

Implements Filter.

Definition at line 363 of file Filter.cpp.

References RegExpFilter::_searchText, Filter::addHotSpot(), Filter::buffer(), Filter::getLineColumn(), and RegExpFilter::newHotSpot().

QRegExp RegExpFilter::regExp ( ) const

inherited

Returns the regular expression which the filter searches for in blocks of text.

Definition at line 355 of file Filter.cpp.

References RegExpFilter::_searchText.

Referenced by RegExpFilter::setRegExp().

void Filter::reset ( void )

inherited

Empties the filters internal buffer and resets the line count back to 0.

All hotspots are deleted.

References Filter::_hotspotList, and Filter::_hotspots.

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

inherited

TODO: Document me.

Definition at line 198 of file Filter.cpp.

References Filter::_buffer, Filter::_linePositions, and Filter::buffer().

void RegExpFilter::setRegExp ( const QRegExp & text )

inherited

Sets the regular expression which the filter searches for in blocks of text.

Regular expressions which match the empty string are treated as not matching anything.
