Constructor Detail

IlvHorizontalDatum

protected IlvHorizontalDatum(String name,
                             IlvEllipsoid ellipsoid)

Initializes an IlvHorizontalDatum object, with the specified name and ellipsoid.

Parameters:

name - The name of the datum.

ellipsoid - The ellipsoid for this datum.

JViews 5.0

IlvHorizontalDatum

protected IlvHorizontalDatum(IlvInputStream stream)
                      throws IlvReadFileException

Reads an IlvHorizontalDatum object from an IlvInputStream.

Throws:

IlvReadFileException

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the object to an IlvOutputStream.

Specified by:

write in interface IlvPersistentObject

Parameters:

stream - the output stream

Throws:

IOException - thrown when an exception occurs during the write operation for this object.

getEllipsoid

public final IlvEllipsoid getEllipsoid()

Returns the ellipsoid for this datum.

getName

public String getName()

Returns the name of this datum.

Since:

JViews 5.0

equivalent

public abstract boolean equivalent(IlvHorizontalDatum d)

Returns true, if the datum passed as the argument describes the same coordinate system as the current object.

equals

public boolean equals(Object object)

Returns true if the specified datum is equal to this datum. The default implementation returns true if the datums are equivalent and if they have the same name.

Overrides:

equals in class Object

Parameters:

object - The object to compare.

Since:

JViews 5.0

GetConverterFactory

public static IlvHorizontalDatumConverterFactory GetConverterFactory()

Returns a factory that can create converters to convert coordinates from one datum to another. The default factory supports the conversion using the Molodensky formula.

SetConverterFactory

public static void SetConverterFactory(IlvHorizontalDatumConverterFactory factory)

Sets a factory to create converters to convert coordinates from one datum to another.

toString

public String toString()

Returns the string representation.

Overrides:

toString in class Object
