protected static final class MathTransformProvider.Delegate extends MathTransformProxy
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
ProviderAffine 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 MathTransformProvider with methods unused for the vast majority of
providers.
