Parameter Syntax and Keywords

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

See Parameter Definitions for links to general information on defining parameters.

See the Table of Contents for a complete list of structures and keywords that apply to specific class members.

• Syntax of Parameters in Class Definitions – Describes the structure of a parameter definition. See Parameter Definitions for links to general information on defining parameters.
• Abstract – Specifies whether this is an abstract parameter.
• Constraint – Specifies a user interface constraint in IDEs for this parameter.
• Deprecated – Specifies that this parameter is deprecated. This keyword is ignored by the class compiler and merely provides a human-readable indicator that the parameter is deprecated.
• Final – Specifies whether this parameter is final (cannot be overridden in subclasses)
• Flags – Modifies the user interface type (in IDEs) for this parameter.
• Internal – Specifies whether this parameter definition is internal (not displayed in the class documentation).
