Package org.geotools.parameter

Parameter implementation. An explanation for this package is provided in the OpenGIS® javadoc. The remaining discussion on this page is specific to the Geotools implementation.

The starting point is often org.opengis.parameter.ParameterDescriptorGroup. Operation implementations need to defines one. Operation usages typically invoke its createValue method and fill the returned object with parameter values. This Geotools package provides the following implementations:

• DefaultParameterDescriptorGroup for the general case.

• ImagingParameterDescriptors for wrappers around Java Advanced Imaging's parameters.

• MatrixParameterDescriptors for matrix parameters, including the number of rows and columns. The total number of parameters in this group vary according the number of rows and columns.
