IlvEllipsoidCollection

public IlvEllipsoidCollection(String filename)
                       throws IOException,
                              IlvCollectionParseException

Creates a new collection of ellipsoids, reading data from the file which name is specified. All ellipsoids from the file are loaded at construction time and cached in the collection.

Parameters:

filename - The name of the input file.

Throws:

IOException - If an I/O error occurs.

IlvCollectionParseException - If an error occurs during the parsing of the definition file.

                              IlvCollectionParseException

Creates a new collection of ellipsoids, reading data from the specified input stream. All ellipsoids from the file are loaded at construction time and cached in the collection.

Parameters:

stream - The input stream.

Throws:

IOException - If an I/O error occurs.

IlvCollectionParseException - If an error occurs during the parsing of the definition file.

Method Detail

getEllipsoids

public final Iterator<IlvEllipsoid> getEllipsoids()

Returns the enumeration of ellipsoids. The elements of the enumeration are instances of IlvEllipsoid.

Returns:

An iterator on all ellipsoids defined in this collection.

getEllipsoid

public final IlvEllipsoid getEllipsoid(String name)

Returns the ellipsoid of specified name if present in the collection. Returns null if the ellipsoid isn't in the collection

Parameters:

name - The name of the ellipsoid.

Returns:

The ellipsoid, or null if not found.

GetKernelCollection

public static IlvEllipsoidCollection GetKernelCollection()

Returns a collection containing the definition of all ellipsoids supported by Perforce JViews Maps.

Returns:

An IlvEllipsoidCollection containing all default ellipsoids definitions.

Merge

public static IlvEllipsoidCollection Merge(IlvEllipsoidCollection collection1,
                                           IlvEllipsoidCollection collection2)

Merge the specified ellipsoid collections.

Parameters:

collection1 - The first ellipsoid collection.

collection2 - The second ellipsoid collection.

Returns:

The merged ellipsoid collection.
