Examples of org.opengis.parameter.ParameterDescriptorGroup.createValue()

org.opengis.parameter.ParameterDescriptorGroup.createValue()

Creates a new instance of {@linkplain ParameterValueGroup parameter value group}initialized with the {@linkplain ParameterDescriptor#getDefaultValue default values}. The {@linkplain ParameterValueGroup#getDescriptor parameter value descriptor}for the created group will be {@code this} object.The number of {@link ParameterValue} objects included must be between the{@linkplain ParameterDescriptor#getMinimumOccurs minimum} and{@linkplain ParameterDescriptor#getMaximumOccurs maximum occurences} required.For example:

For {@link ParameterDescriptor} with cardinality 1:* a {@link ParameterValue} willbe included with the {@linkplain ParameterDescriptor#getDefaultValue default value}(even if this default value is null).
For {@link ParameterDescriptor} with cardinality 0:* no entry is required.{@link ParameterValue} entries may be created only as needed.

@return A new parameter instance initialized to the default value.

         * parameter names.
