Member Function Documentation

area()

double TSLMultiPolygonPart::area

(

)

const

Returns the area of this TSLMultiPolygonPart.

inner() [1/2]

TSLCoordSet * TSLMultiPolygonPart::inner

(

int

index

)

const

Query the coordinates of the inner boundary at the specified index.

Note that the coordset returned is a copy of the internal version and is owned by the caller.

Parameters

index

Index of inner boundary to query.

Returns

NULL if no such inner exists.

inner() [2/2]

const TSLCoord * TSLMultiPolygonPart::inner	(	int	index,
		int &	numCoords ) const

Returns the coordinates associated with the given inner.

Parameters

index	index of inner boundary to query
numCoords	returns the number of coordinates

numInners()

int TSLMultiPolygonPart::numInners

(

)

const

Returns the number of inners in this TSLMultiPolygonPart.

outer() [1/2]

TSLCoordSet * TSLMultiPolygonPart::outer

(

)

const

Returns a pointer to a coordinate set describing the outer.

Note that the coordset returned is a copy of the internal version and is owned by the caller.

outer() [2/2]

const TSLCoord * TSLMultiPolygonPart::outer

(

int &

numCoords

)

const

Returns the coordinates associated with the outer.

Parameters

numCoords

returns the number of coordinates

polygon()

TSLPolygon * TSLMultiPolygonPart::polygon

(

)

const

Returns the TSLPolygon associated with this TSLMultiPolygonPart.

Note that the polygon returned is a copy of the internal version and is owned by the caller.

Note also that the feature id of the returned TSLPolygon will always be zero.
