Multisurface is a non-instantiable type in SQL.

Member Function Documentation

◆ accept()

bool gis::Multisurface::accept ( Geometry_visitor v)
overridepure virtual

Applies a hierarchical visitor to this geometry.

See also
gis::Geometry_visitor
Parameters
vA hierarchical visitor.
Return values
trueThe execution was aborted by the visitor.
falseThe execution completed.

Implements gis::Geometrycollection.

Implemented in gis::Multipolygon, gis::Geographic_multipolygon, and gis::Cartesian_multipolygon.

◆ type()

Geometry_type gis::Multisurface::type ( ) const
overridepure virtual

Gets the geometry type of the object.

Returns
The type of this object

Reimplemented from gis::Geometrycollection.

Implemented in gis::Multipolygon.
