  • Constructor Details

    • AbstractProvider

      public AbstractProvider(ParameterDescriptorGroup parameters)
      Constructs a math transform provider from a set of parameters. The provider identifiers will be the same than the parameter ones.
      Parameters:
      parameters - The set of parameters (never null).

  • Method Details

    • getOperationType

      public Class<? extends Projection> getOperationType()
      Returns the operation type for this map projection.
      Overrides:
      getOperationType in class MathTransformProvider
      Returns:
      The GeoAPI interface implemented by this operation.

    • doubleValue

      protected static double doubleValue(ParameterDescriptor param, ParameterValueGroup group) throws ParameterNotFoundException
      Returns the parameter value for the specified operation parameter in standard units. Values are automatically converted into the standard units specified by the supplied param argument, except degrees which are converted to radians. This conversion is performed because the radians units are standard for all internal computations in the map projection package. For example they are the standard units for latitudeOfOrigin and centralMeridian fields in the MapProjection class.
      Parameters:
      param - The parameter to look for.
      group - The parameter value group to search into.
      Returns:
      The requested parameter value.
      Throws:
      ParameterNotFoundException - if the parameter is not found.
