Detailed Description

Accumulate a geometry's all vertex points into a multipoint.

It implements the WKB_scanner_event_handler interface so as to be registered into wkb_scanner and be notified of WKB data events.

Constructor & Destructor Documentation

Point_accumulator::Point_accumulator ( Gis_multi_point * mpts )

inlineexplicit

void Point_accumulator::on_wkb_end ( const void * wkb )

inlineoverridevirtual

Notified when scanner sees the end of a geometry WKB.

Parameters

wkb	the position of the first byte after the WKB byte string which the scanner just scanned.

void Point_accumulator::on_wkb_start	(	Geometry::wkbByteOrder	bo,
		Geometry::wkbType	geotype,
		const void *	wkb,
		uint32	len,
		bool	has_hdr
	)

inlineoverridevirtual

Notified when scanner sees the start of a geometry WKB.

Parameters

bo	byte order of the WKB.
geotype	geometry type of the WKB;
wkb	WKB byte string, the first byte after the WKB header if any.
len	NO. of bytes of the WKB byte string starting from wkb. There can be many geometries in the [wkb, wkb+len) buffer.
has_hdr	whether there is a WKB header right before 'wkb' in the byte string.
