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.

Member Function Documentation

◆ on_wkb_end()

void Point_accumulator::on_wkb_end ( const void *  wkb)
inlineoverridevirtual

Notified when scanner sees the end of a geometry WKB.

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

Implements WKB_scanner_event_handler.

◆ on_wkb_start()

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
bobyte order of the WKB.
geotypegeometry type of the WKB;
wkbWKB byte string, the first byte after the WKB header if any.
lenNO. of bytes of the WKB byte string starting from wkb. There can be many geometries in the [wkb, wkb+len) buffer.
has_hdrwhether there is a WKB header right before 'wkb' in the byte string.

Implements WKB_scanner_event_handler.
