Member Function Documentation

visit() [1/13]

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

inlineoverridevirtual

Implements gis::Geometry_visitor.

Reimplemented in gis::Coordinate_range_visitor, gis::Longitude_range_normalizer, gis::Wkb_size_visitor, and gis::Wkb_visitor.

visit() [2/13]

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.
