Role Query

fmp.system.RoleQuery is a utility class used to determine the roles of a given Node. This is necessary because the same metamodel class is used to represent elements in conceptually different places. The following functions return constants defined in the RoleQuery class.

• public int getLocationType(Node node) returns:
  CONFIGURATION,
  CONFIGURATION_PROPERTIES,

  MODEL_PROPERTIES,
  METAMODEL,
  METAMODEL_PROPERTIES,
  METAMETAMODEL.
• public int getNodeType(Node node) returns:
  UNDEFINED,
  ROOT_FEATURE,
  SOLITARY_FEATURE,
  GROUPED_FEATURE,
  SOLITARY_REFERENCE,
  GROUPED_REFERENCE,
  FEATURE_GROUP,
  FEATURE_MODEL.
• public int getPropertyRole(Node node) returns:
  NONE,
  NAME,
  ID,
  MIN_OCCUR,
  MAX_OCCUR,
  DESCRIPTION,
  ATTRIBUTE,
  TYPE_GROUP,
  TYPE,
  VALUE,
