Constructor Detail

MapProjection.Provider

protected MapProjection.Provider(String classname,
                                 int nameKey)

Construct a new provider.

Parameters:

classname - The classification name.

nameKey - Resources key for a human readable name. This is used for MathTransformProvider.getName(java.util.Locale) implementation.

Method Detail

create

public final MathTransform create(javax.media.jai.ParameterList parameters)

Create a new map projection for a parameter list.

Specified by:

create in class MathTransformProvider

Parameters:

parameters - The parameter values in standard units.

Returns:

A MathTransform object of this classification.

create

protected abstract Object create(Projection parameters)

Create a new map projection. NOTE: The returns type should be MathTransform, but as of JDK 1.4-beta3, it force class loading for all projection classes (MercatorProjection, etc.) before than necessary. Changing the returns type to Object is a trick to avoid too early class loading...
