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.

Notified when scanner sees the end of a geometry WKB.
wkb | the position of the first byte after the WKB byte string which the scanner just scanned. |
Implements WKB_scanner_event_handler.

inlineoverridevirtual |
Notified when scanner sees the start of a geometry WKB.
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. |
Implements WKB_scanner_event_handler.
