Member Function Documentation

virtual void OGRPolyhedralSurface::accept ( IOGRGeometryVisitor visitor)
inlineoverridevirtual

Accept a visitor.

Implements OGRGeometry.

Reimplemented in OGRTriangulatedSurface.

virtual void OGRPolyhedralSurface::accept ( IOGRConstGeometryVisitor visitor) const
inlineoverridevirtual

Accept a visitor.

Implements OGRGeometry.

Reimplemented in OGRTriangulatedSurface.

OGRErr OGRPolyhedralSurface::addGeometry ( const OGRGeometry poNewGeom)
virtual

Add a new geometry to a collection.

Only a POLYGON can be added to a POLYHEDRALSURFACE.

Returns
OGRErr OGRERR_NONE if the polygon is successfully added

Reimplemented in OGRTriangulatedSurface.

OGRErr OGRPolyhedralSurface::addGeometryDirectly ( OGRGeometry poNewGeom)

Add a geometry directly to the container.

This method is the same as the C function OGR_G_AddGeometryDirectly().

There is no SFCOM analog to this method.

Parameters
poNewGeomgeometry to add to the container.
Returns
OGRERR_NONE if successful, or OGRERR_UNSUPPORTED_GEOMETRY_TYPE if the geometry type is illegal for the type of geometry container.
void OGRPolyhedralSurface::assignSpatialReference ( OGRSpatialReference poSR)
overridevirtual

Assign spatial reference to this object.

Any existing spatial reference is replaced, but under no circumstances does this result in the object being reprojected. It is just changing the interpretation of the existing geometry. Note that assigning a spatial reference increments the reference count on the OGRSpatialReference, but does not copy it.

Starting with GDAL 2.3, this will also assign the spatial reference to potential sub-geometries of the geometry (OGRGeometryCollection, OGRCurvePolygon/OGRPolygon, OGRCompoundCurve, OGRPolyhedralSurface and their derived classes).

This is similar to the SFCOM IGeometry::put_SpatialReference() method.

This method is the same as the C function OGR_G_AssignSpatialReference().

Parameters
poSRnew spatial reference system to apply.

Reimplemented from OGRGeometry.

ChildType** OGRPolyhedralSurface::begin ( )
inline

Return begin of iterator.

Since
GDAL 2.3
const ChildType* const* OGRPolyhedralSurface::begin ( ) const
inline

Return begin of iterator.

Since
GDAL 2.3
OGRMultiPolygon * OGRPolyhedralSurface::CastToMultiPolygon ( OGRPolyhedralSurface poPS)
static

Casts the OGRPolyhedralSurface to an OGRMultiPolygon.

The passed in geometry is consumed and a new one returned (or NULL in case of failure)

Parameters
poPSthe input geometry - ownership is passed to the method.
Returns
new geometry.
OGRGeometry * OGRPolyhedralSurface::clone ( ) const
overridevirtual

Make a copy of this object.

This method relates to the SFCOM IGeometry::clone() method.

This method is the same as the C function OGR_G_Clone().

Returns
a new object instance with the same geometry, and spatial reference system as the original.

Implements OGRGeometry.

void OGRPolyhedralSurface::empty ( )
overridevirtual

Clear geometry information.

This restores the geometry to its initial state after construction, and before assignment of actual geometry.

This method relates to the SFCOM IGeometry::Empty() method.

This method is the same as the C function OGR_G_Empty().

Implements OGRGeometry.

OGRBoolean OGRPolyhedralSurface::Equals ( const OGRGeometry ) const
overridevirtual

Returns TRUE if two geometries are equivalent.

This operation implements the SQL/MM ST_OrderingEquals() operation.

The comparison is done in a structural way, that is to say that the geometry types must be identical, as well as the number and ordering of sub-geometries and vertices. Or equivalently, two geometries are considered equal by this method if their WKT/WKB representation is equal. Note: this must be distinguished for equality in a spatial way (which is the purpose of the ST_Equals() operation).

This method is the same as the C function OGR_G_Equals().

Returns
TRUE if equivalent or FALSE otherwise.

Implements OGRGeometry.

OGRErr OGRPolyhedralSurface::exportToWkb ( OGRwkbByteOrder  eByteOrder,
unsigned char *  pabyData,
OGRwkbVariant  eWkbVariant = wkbVariantOldOgc 
) const
overridevirtual

Convert a geometry into well known binary format.

This method relates to the SFCOM IWks::ExportToWKB() method.

This method is the same as the C function OGR_G_ExportToWkb() or OGR_G_ExportToIsoWkb(), depending on the value of eWkbVariant.

Parameters
eByteOrderOne of wkbXDR or wkbNDR indicating MSB or LSB byte order respectively.
pabyDataa buffer into which the binary representation is written. This buffer must be at least OGRGeometry::WkbSize() byte in size.
eWkbVariantWhat standard to use when exporting geometries with three dimensions (or more). The default wkbVariantOldOgc is the historical OGR variant. wkbVariantIso is the variant defined in ISO SQL/MM and adopted by OGC for SFSQL 1.2.
Returns
Currently OGRERR_NONE is always returned.

Implements OGRGeometry.

OGRErr OGRPolyhedralSurface::exportToWkt ( char **  ppszDstText,
OGRwkbVariant  eWkbVariant = wkbVariantOldOgc 
) const
overridevirtual

Convert a geometry into well known text format.

This method relates to the SFCOM IWks::ExportToWKT() method.

This method is the same as the C function OGR_G_ExportToWkt().

Parameters
ppszDstTexta text buffer is allocated by the program, and assigned to the passed pointer. After use, *ppszDstText should be freed with CPLFree().
eWkbVariantthe specification that must be conformed too :
  • wbkVariantOgc for old-style 99-402 extended dimension (Z) WKB types
  • wbkVariantIso for SFSQL 1.2 and ISO SQL/MM Part 3
Returns
Currently OGRERR_NONE is always returned.

Implements OGRGeometry.

void OGRPolyhedralSurface::flattenTo2D ( )
overridevirtual

Convert geometry to strictly 2D.

In a sense this converts all Z coordinates to 0.0.

This method is the same as the C function OGR_G_FlattenTo2D().

Implements OGRGeometry.

double OGRPolyhedralSurface::get_Area ( ) const
overridevirtual

Returns the area enclosed.

This method is built on the SFCGAL library, check it for the definition of the geometry operation. If OGR is built without the SFCGAL library, this method will always return -1.0

Returns
area enclosed by the PolyhedralSurface

Implements OGRSurface.

int OGRPolyhedralSurface::getDimension ( ) const
overridevirtual

Get the dimension of this object.

This method corresponds to the SFCOM IGeometry::GetDimension() method. It indicates the dimension of the object, but does not indicate the dimension of the underlying space (as indicated by OGRGeometry::getCoordinateDimension()).

This method is the same as the C function OGR_G_GetDimension().

Returns
0 for points, 1 for lines and 2 for surfaces.

Implements OGRGeometry.

void OGRPolyhedralSurface::getEnvelope ( OGREnvelope *  psEnvelope) const
overridevirtual

Computes and returns the bounding envelope for this geometry in the passed psEnvelope structure.

This method is the same as the C function OGR_G_GetEnvelope().

Parameters
psEnvelopethe structure in which to place the results.

Implements OGRGeometry.

void OGRPolyhedralSurface::getEnvelope ( OGREnvelope3D *  psEnvelope) const
overridevirtual

Computes and returns the bounding envelope (3D) for this geometry in the passed psEnvelope structure.

This method is the same as the C function OGR_G_GetEnvelope3D().

Parameters
psEnvelopethe structure in which to place the results.
Since
OGR 1.9.0

Implements OGRGeometry.

const char * OGRPolyhedralSurface::getGeometryName ( ) const
overridevirtual

Fetch WKT name for geometry type.

There is no SFCOM analog to this method.

This method is the same as the C function OGR_G_GetGeometryName().

Returns
name used for this geometry type in well known text format. The returned pointer is to a static internal string and should not be modified or freed.

Implements OGRGeometry.

Reimplemented in OGRTriangulatedSurface.

OGRGeometry * OGRPolyhedralSurface::getGeometryRef ( int  i)

Fetch geometry from container.

This method returns a pointer to an geometry within the container. The returned geometry remains owned by the container, and should not be modified. The pointer is only valid until the next change to the geometry container. Use IGeometry::clone() to make a copy.

Parameters
ithe index of the geometry to fetch, between 0 and getNumGeometries() - 1.
Returns
pointer to requested geometry.
const OGRGeometry * OGRPolyhedralSurface::getGeometryRef ( int  i) const

Fetch geometry from container.

This method returns a pointer to an geometry within the container. The returned geometry remains owned by the container, and should not be modified. The pointer is only valid until the next change to the geometry container. Use IGeometry::clone() to make a copy.

Parameters
ithe index of the geometry to fetch, between 0 and getNumGeometries() - 1.
Returns
pointer to requested geometry.
OGRwkbGeometryType OGRPolyhedralSurface::getGeometryType ( ) const
overridevirtual

Returns the WKB Type of PolyhedralSurface.

Implements OGRGeometry.

Reimplemented in OGRTriangulatedSurface.

int OGRPolyhedralSurface::getNumGeometries ( ) const

Fetch number of geometries in PolyhedralSurface.

Returns
count of children geometries. May be zero.
OGRBoolean OGRPolyhedralSurface::hasCurveGeometry ( int  bLookForNonLinear = FALSE) const
overridevirtual

Returns if this geometry is or has curve geometry.

Returns if a geometry is, contains or may contain a CIRCULARSTRING, COMPOUNDCURVE, CURVEPOLYGON, MULTICURVE or MULTISURFACE.

If bLookForNonLinear is set to TRUE, it will be actually looked if the geometry or its subgeometries are or contain a non-linear geometry in them. In which case, if the method returns TRUE, it means that getLinearGeometry() would return an approximate version of the geometry. Otherwise, getLinearGeometry() would do a conversion, but with just converting container type, like COMPOUNDCURVE -> LINESTRING, MULTICURVE -> MULTILINESTRING or MULTISURFACE -> MULTIPOLYGON, resulting in a "loss-less" conversion.

This method is the same as the C function OGR_G_HasCurveGeometry().

Parameters
bLookForNonLinearset it to TRUE to check if the geometry is or contains a CIRCULARSTRING.
Returns
TRUE if this geometry is or has curve geometry.
Since
GDAL 2.0

Reimplemented from OGRGeometry.

OGRErr OGRPolyhedralSurface::importFromWkb ( const unsigned char *  pabyData,
int  nSize,
OGRwkbVariant  eWkbVariant,
int &  nBytesConsumedOut 
)
overridevirtual

Assign geometry from well known binary data.

The object must have already been instantiated as the correct derived type of geometry object to match the binaries type. This method is used by the OGRGeometryFactory class, but not normally called by application code.

This method relates to the SFCOM IWks::ImportFromWKB() method.

This method is the same as the C function OGR_G_ImportFromWkb().

Parameters
pabyDatathe binary input data.
nSizethe size of pabyData in bytes, or -1 if not known.
eWkbVariantif wkbVariantPostGIS1, special interpretation is done for curve geometries code
nBytesConsumedOutoutput parameter. Number of bytes consumed.
Returns
OGRERR_NONE if all goes well, otherwise any of OGRERR_NOT_ENOUGH_DATA, OGRERR_UNSUPPORTED_GEOMETRY_TYPE, or OGRERR_CORRUPT_DATA may be returned.
Since
GDAL 2.3

Implements OGRGeometry.

OGRBoolean OGRPolyhedralSurface::IsEmpty ( ) const
overridevirtual

Checks if the PolyhedralSurface is empty.

Returns
TRUE if the PolyhedralSurface is empty, FALSE otherwise

Implements OGRGeometry.

OGRErr OGRPolyhedralSurface::PointOnSurface ( OGRPoint poPoint) const
overridevirtual

This method relates to the SFCOM ISurface::get_PointOnSurface() method.

NOTE: Only implemented when GEOS included in build.

Parameters
poPointpoint to be set with an internal point.
Returns
OGRERR_NONE if it succeeds or OGRERR_FAILURE otherwise.

Reimplemented from OGRSurface.

OGRErr OGRPolyhedralSurface::removeGeometry ( int  iGeom,
int  bDelete = TRUE 
)

Remove a geometry from the container.

Removing a geometry will cause the geometry count to drop by one, and all "higher" geometries will shuffle down one in index.

Parameters
iGeomthe index of the geometry to delete. A value of -1 is a special flag meaning that all geometries should be removed.
bDeleteif TRUE the geometry will be deallocated, otherwise it will not. The default is TRUE as the container is considered to own the geometries in it.
Returns
OGRERR_NONE if successful, or OGRERR_FAILURE if the index is out of range.
void OGRPolyhedralSurface::setCoordinateDimension ( int  nNewDimension)
overridevirtual

Set the coordinate dimension.

This method sets the explicit coordinate dimension. Setting the coordinate dimension of a geometry to 2 should zero out any existing Z values. This will also remove the M dimension if present before this call.

Parameters
nNewDimensionNew coordinate dimension value, either 2 or 3.

Reimplemented from OGRGeometry.

OGRErr OGRPolyhedralSurface::transform ( OGRCoordinateTransformation poCT)
overridevirtual

Apply arbitrary coordinate transformation to geometry.

This method will transform the coordinates of a geometry from their current spatial reference system to a new target spatial reference system. Normally this means reprojecting the vectors, but it could include datum shifts, and changes of units.

Note that this method does not require that the geometry already have a spatial reference system. It will be assumed that they can be treated as having the source spatial reference system of the OGRCoordinateTransformation object, and the actual SRS of the geometry will be ignored. On successful completion the output OGRSpatialReference of the OGRCoordinateTransformation will be assigned to the geometry.

This method is the same as the C function OGR_G_Transform().

Parameters
poCTthe transformation to apply.
Returns
OGRERR_NONE on success or an error code.

Implements OGRGeometry.

int OGRPolyhedralSurface::WkbSize ( ) const
overridevirtual

Returns size of related binary representation.

This method returns the exact number of bytes required to hold the well known binary representation of this geometry object. Its computation may be slightly expensive for complex geometries.

This method relates to the SFCOM IWks::WkbSize() method.

This method is the same as the C function OGR_G_WkbSize().

Returns
size of binary representation in bytes.

Implements OGRGeometry.
