Detailed Description

An utility class for writing a PostGIS EWKB.

Definition at line 48 of file EWKBWriter.h.

Constructor & Destructor Documentation

te::pgis::EWKBWriter::EWKBWriter	(	char *	ewkb,

byteOrder	The byte order to be used to encode the WKB.

te::pgis::EWKBWriter::~EWKBWriter ( )

Destructor.

Member Function Documentation

void te::pgis::EWKBWriter::reset	(	char *	ewkb,
		te::common::MachineByteOrder	byteOrder = `te::common::NDR`
	)

It resets the EWKB writer an allows a new geometry to be seriealized to a new buffer.

Parameters

ewkb	A pointer to a buffer to output the ewkb. It must have at least the size in bytes necessary to write the EWKB.
byteOrder	The byte order to be used to encode the EWKB.

void te::pgis::EWKBWriter::write ( const te::gm::Geometry * geom )

It serializes the geometry to an EWKB representation into the specified buffer.

Parameters

geom	The geometry to be serialized.

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

static void te::pgis::EWKBWriter::write	(	const te::gm::Geometry *	geom,
		char *	ewkb,
		te::common::MachineByteOrder	byteOrder = `te::common::NDR`
	)

static

It serializes the geometry to an EWKB representation into the specified buffer.

The ewkb parameter must have at least geom.getWkbSize() + 4 bytes in order to be used. Don't pass a NULL pointer or a buffer smaller than the size needed. Note that the EWKB will be on the specified byte order.

Parameters

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