Parameter Keywords

This reference describes the keywords that apply to a class parameter. These keywords (also known as class attributes) generally affect the compiler.

For general information on parameter definitions, see “Parameter Definitions.”

  • Abstract – Specifies whether this is an abstract parameter.
  • Constraint – Specifies a user interface constraint for this parameter.
  • Deprecated – Specifies that this parameter is deprecated. This keyword is ignored by the class compiler and by Studio, but is used by Atelier.
  • Final – Specifies whether this parameter is final (cannot be overridden in subclasses)
  • Flags – Modifies the user interface type (in Studio) for this parameter.
  • Internal – Specifies whether this parameter definition is internal (not displayed in the class documentation).
