void te::gm::WKBWriter::write ( const Geometry * geom )

It serializes the geometry to a WKB representation into the specified buffer.

Parameters

geom	The geometry to be serialized.

Note: You must call reset in successive calls to this method.

void te::gm::WKBWriter::write	(	const Geometry *	geom,
		char *	wkb,
		te::common::MachineByteOrder	byteOrder = `te::common::NDR`
	)

static

It serializes the geometry to a WKB representation into the specified buffer.

The wkb parameter must have at least geom.getWkbSize() in order to be used. Don't pass a NULL pointer or a buffer smaller than the size needed. Note that the WKB will be on the specified byte order.

Parameters

geom	The geometry to be serialized.
wkb	The buffer where the geometry will be serialized.
byteOrder	The byte order used to store/serialize the geometry.
