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.

| AbstractParameter.java | Class | Abstract parameter value or group of parameter values. |
| AbstractParameterDescriptor.java | Class | Abstract definition of a parameter or group of parameters used by an operation method. |
| DefaultParameterDescriptor.java | Class | The definition of a parameter used by an operation method.
For
most parameter values are numeric, but other types
of parameter values are possible.
For numeric values, the
is usually
.class,
.class or
some other Java wrapper class.
This class contains numerous convenience constructors. |

Design note
This class contains some methods working on a specific parameter in a group (e.g.
,
, etc.).
Parameters are identified by their
instead of
their full
object, because:
- The parameter descriptor may not be always available.

| ParametersTest.java | Class | Tests the org.geotools.parameter package. |
| ParameterValueList.java | Class | The list to be returned by
Parameter.values . |
| ParameterWriter.java | Class | Format
or
in a tabular format.
This writer assumes a monospaced font and an encoding capable to provide
drawing box characters (e.g. |
