4.7 User-defined types
A user-defined type is a schema object, identified by a . The definition of a userdefined type specifies a number of components, including in particular a list of attribute definitions. Although the attribute definitions are said to define the representation of the user-defined type, in fact they implicitly define certain functions (observers and mutators) that are part of the interface of the user-defined type; physical representations of user-defined type values are implementation-dependent.
The representation of a user-defined type is expressed either as a single data type (some predefined data type, called the source type), in which case the user-defined type is said to be a distinct type, or as a list of attribute definitions, in which case it is said to be a structured type.
A user-defined type is described by a user-defined type descriptor. A user-defined type descriptor contains:
- The name of the user-defined type ( ). This is the type designator of that type, used in type precedence lists (see Subclause 9.5, "Type precedence list determination").
- An indication of whether the user-defined type is a structured type or a distinct type.
The following features are supported:

getPredefinedRepresentation
public PredefinedDataType getPredefinedRepresentation()
- Returns the value of the 'Predefined Representation' containment reference.
If the meaning of the 'Predefined Representation' reference isn't clear,
there really should be more of a description here...
- Returns:
- the value of the 'Predefined Representation' containment reference.

setPredefinedRepresentation
public void setPredefinedRepresentation(PredefinedDataType value)
- Sets the value of the '
Predefined Representation
' containment reference.
- Parameters:
value
- the new value of the 'Predefined Representation' containment reference.- See Also:
