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

org.opengis.parameter.ParameterDescriptorGroup.descriptor()
Returns the parameter descriptor in this group for the specified {@linkplain Identifier#getCode identifier code}. @param name The case insensitive {@linkplain Identifier#getCode identifier code} of theparameter to search for. @return The parameter for the given identifier code. @throws ParameterNotFoundException if there is no parameter for the given identifier code.
