Member Function Documentation

continue_scan()

bool Is_empty_geometry::continue_scan ( ) const

inlineoverridevirtual

Reimplemented from WKB_scanner_event_handler.

on_wkb_end()

void Is_empty_geometry::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.

Implements WKB_scanner_event_handler.

on_wkb_start()

void Is_empty_geometry::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.

Implements WKB_scanner_event_handler.
