Types
enum AttributeMode {NORMAL, READONLY};
struct AttributeDescription {
Identifier name;
RepositoryId id;
RepositoryId defined_in;
TypeCode type;
AttributeMode mode;
};
The describe method, inherited from Contained, returns an AttributeDescription structure
in the value member of the Description structure (defined in the Contained class).
Attributes
Following is a list of each available attribute, with its corresponding type in parentheses,
followed by a description of its purpose:
type (TypeCode)
The TypeCode that represents the type of the attribute. The TypeCode
returned by the “_get_” form of the type attribute is contained in the
receiving AttributeDef object, which retains ownership. Thus, the returned
TypeCode should not be freed. To obtain a separate copy, use the
TypeCode_copy operation. The “_set_” form of the attribute makes a
private copy of the TypeCode you supply, to keep in the receiving object.
You retain ownership of the passed TypeCode.
mode (AttributeMode)
The AttributeMode of the attribute (NORMAL or READONLY).
