    package org.geotools.parameter
  
  
  {@linkplain org.geotools.parameter.Parameter Parameter} implementation.
  An explanation for this package is provided in the
  {@linkplain org.opengis.parameter OpenGIS® javadoc}.
  The remaining discussion on this page is specific to the Geotools implementation.

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

  
    {@link org.geotools.parameter.DefaultParameterDescriptorGroup} for the general case.

    {@link org.geotools.parameter.ImagingParameterDescriptors} for wrappers around
        {@linkplain javax.media.jai.ParameterListDescriptor Java Advanced Imaging's parameters}.

    {@link org.geotools.parameter.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.
