Field Details

ml0

protected final double ml0

Meridian distance at the latitudeOfOrigin. Used for calculations for the ellipsoid.

Constructor Details

Abstract

protected Abstract(ParameterValueGroup parameters)
            throws ParameterNotFoundException

Constructs a new map projection from the supplied parameters.

Parameters:

parameters - The parameter values in standard units.

Throws:

ParameterNotFoundException - if a mandatory parameter is missing.

Method Details

getParameterDescriptors

public ParameterDescriptorGroup getParameterDescriptors()

Returns the parameter descriptors for this map projection. This is used for a providing a default implementation of MapProjection.getParameterValues(), as well as arguments checking.

Specified by:

getParameterDescriptors in class MapProjection

Returns:

The parameter descriptors for this math transform, or null.

• OperationMethod.getParameters()

getToleranceForAssertions

protected double getToleranceForAssertions(double longitude,
 double latitude)

Description copied from class: MapProjection

Maximal error (in metres) tolerated for assertions, if enabled. When assertions are enabled, every direct projection is followed by an inverse projection, and the result is compared to the original coordinate. If a distance greater than the tolerance level is found, then an ProjectionException will be thrown. Subclasses should override this method if they need to relax the tolerance level.

Overrides:

getToleranceForAssertions in class MapProjection

Parameters:

longitude - The longitude in decimal degrees.

latitude - The latitude in decimal degrees.

Returns:

The tolerance level for assertions, in meters.

hashCode

public int hashCode()

Returns a hash value for this projection.

Overrides:

hashCode in class MapProjection

equals

public boolean equals(Object object)

Compares the specified object with this map projection for equality.

Overrides:

equals in class MapProjection

Parameters:

object - The object to compare with this transform.

Returns:

true if the given object is a transform of the same class and if, given identical source position, the transformed position would be the equals.
