Constructor & Destructor Documentation

◆ Wkb_visitor()

gis::Wkb_visitor::Wkb_visitor	(	const dd::Spatial_reference_system *	srs,
		char *	wkb,
		size_t	wkb_size
	)

inline

Construct a new WKB visitor.

Member Function Documentation

◆ visit() [1/14]

bool gis::Nop_visitor::visit ( Curve * c )

inlineoverridevirtual

Reimplemented from gis::Nop_visitor.

◆ visit() [2/14]

bool gis::Nop_visitor::visit ( Geometry * g )

inlineoverridevirtual

Visits a geometry.

This is called on each non-compound geometry and between visiting descendants. E.g., visit(Linestring *) will be called after visiting the first point in the linestring, then after visiting the second, etc., but not after visiting the last point.

Parameters

g	The geometry to visit.

Return values

true	Abort visitor execution.
false	Continue visitor execution.

Reimplemented from gis::Nop_visitor.
