Method Detail

### createValue

    @Extension
    GeneralParameterValue createValue()

  Creates a new instance of parameter value or group initialized with the default value(s). The parameter value descriptor for the created parameter value(s) will be `this` object.

### getMinimumOccurs

    @UML(identifier="minimumOccurs",
         obligation=OPTIONAL,
         specification=ISO_19111)
    int getMinimumOccurs()

  The minimum number of times that values for this parameter group or parameter are required. The default value is one. A value of 0 means an optional parameter.

### getMaximumOccurs

    @UML(identifier="CC_OperationParameterGroup.maximumOccurs",
         obligation=OPTIONAL,
         specification=ISO_19111)
    int getMaximumOccurs()

  The maximum number of times that values for this parameter group or parameter can be included. For a single parameter, the value is always 1. For a parameter group, it may vary. The default value is one.
