Method Detail

createValue

@Extension
ParameterValueGroup createValue()

Creates a new instance of parameter value group initialized with the default values. The parameter value descriptor for the created group will be this object. The number of ParameterValue objects included must be between the minimum and maximum occurences required. For example:

• For ParameterDescriptor with cardinality 1:* a ParameterValue will be included with the default value (even if this default value is null).
• For ParameterDescriptor with cardinality 0:* no entry is required. ParameterValue entries may be created only as needed.

descriptors

@UML(identifier="includesParameter",
     obligation=MANDATORY,
     specification=ISO_19111)
List<GeneralParameterDescriptor> descriptors()

Returns the parameters in this group.

descriptor

@Extension
GeneralParameterDescriptor descriptor(String name)
                                      throws ParameterNotFoundException

Returns the parameter descriptor in this group for the specified identifier code.

Parameters:

name - The case insensitive identifier code of the parameter to search for.

Returns:

The parameter for the given identifier code.

Throws:

ParameterNotFoundException - if there is no parameter for the given identifier code.
