Attributes

Inherited Attributes

• defaultValue : EString (optional)
  The default value of the fieldValue. This value should be the same as the defaultValue of the contained fieldValue, and is provided to simplify end-user implementation.
• generatedRule : EString (optional)
  To assist in debugging, this attribute may be populated with the name of the model completion rule that created this element. More extensive traceability support may be provided in the future.
• id : EString (optional)
  A unique identifier for this model element. Should be globally unique.
• isGenerated : EBoolean (optional)
  Set to true if the current element has been generated.
• name : EString (optional)
  A non-unique string that names a given object.
• overridden : EBoolean (optional)
  If a GeneratesElements is overridden, then this element will not generate any elements directly.
• overriddenNames : EString (optional)
  When applying model completion, no NamedElements with these names will be generated by this element.
• renderOrder : EInt (optional)
  VisibleThings are rendered in an ascending renderOrder order.
• visible : EBoolean (optional)
  If false, this VisibleThing will not initially be rendered to the user, until it has been shown.
