  org.geotools.referencing.operation.transform.MathTransformProxy
      org.geotools.referencing.operation.MathTransformProvider.Delegate

All Implemented Interfaces:

org.opengis.referencing.operation.MathTransform, java.io.Serializable

Enclosing class:

MathTransformProvider

protected static final class MathTransformProvider.Delegate

extends MathTransformProxy

The result of a call to createMathTransform. This class encapsulates a reference to the originating provider as well as the created math transform. This information is needed when a provider delegates the work to an other provider according the parameter values. For example a generic instance of ProviderAffine may delegates the creation of an affine transform to an other instance with source and target dimensions matching the supplied parameters, because those dimensions determine the set of legal "elt_j_i" parameters.

Most math transform provider do not delegate their work to an other one, and consequently do not need this class.

Future Geotools version may extends this class for handling more information than just the transform creator. This class is more convenient than adding new methods right into MathTransformProvider, because it is sometime difficult for a provider to infer all the conditions prevaling when createMathTransform was executed. Furthermore, it avoid to pollute with methods unused for the vast majority of providers.
