Constructor & Destructor Documentation

FDO_GEOM_API FdoIGeometry::FdoIGeometry (   )  [inline, protected]

virtual FDO_GEOM_API FdoIGeometry::~FdoIGeometry (   )  [inline, protected, virtual]

Member Function Documentation

virtual FDO_GEOM_API FdoGeometryType FdoIGeometry::GetDerivedType (   )  const [pure virtual]
 

Gets the type of the most-derived interface in the Geometry package for this object.

Remarks:
The derived type indicates to what class the object may safely be cast.
Returns:
Returns the derived type

virtual FDO_GEOM_API FdoInt32 FdoIGeometry::GetDimensionality (   )  const [pure virtual]
 

Gets the dimensionality of ordinates in this object.

Remarks:
Values are from the FdoDimensionality enumeration. A return type of "FdoInt32" is used instead of the enumeration, catering to typical use with bit masking.
Returns:
Returns the ordinate dimensionality

virtual FDO_GEOM_API FdoIEnvelope* FdoIGeometry::GetEnvelope (   )  const [pure virtual]
 

Gets the envelope for the Geometry.

Returns:
Returns the envelope

virtual FDO_GEOM_API FdoString* FdoIGeometry::GetText (   )  [pure virtual]
 

Gets the text string representation of this Geometry.

Remarks:
This object retains ownership of the string. The caller should NOT attempt to free it. The text string may be retained in memory by the object indefinitely. Calling this method on a large number of Geometries that are retained in memory may cause a noticable increase in memory consumption.
Returns:
Returns the text string
