 Attribute Detail

isUnique

public Boolean isUnique

True if the members of a given value of the type are required to be distinct; else False. isUnique is always True for a SET type, always False for a BAG type, and True for LIST and ARRAY types if and only if the UNIQUE keyword is present in the type designation

See 8.2 of ISO 10303-11:2004.

lower_bound

public SizeConstraint lower_bound

represents the appearance of a lower-bound constraint in syntactic designation for the aggregation type. For this purpose the appearance of an explicit zero ('0') value may be considered to represent no lower-bound constraint; and the lower-bound relationship need not appear. (The appearance of a lower-bound expression that may evaluate to zero shall always be represented by a lower-bound relationship.)

See 8.2.x of ISO 10303-11:2004.

member_type

public InstantiableType member_type

arrow_up

upper_bound

public SizeConstraint upper_bound

represents the appearance of an upper-bound constraint in syntactic designation for the aggregation type. For this purpose the appearance of an explicit indeterminate value ('?') is considered to represent no upper-bound constraint, and shall not be represented by an upper-bound relationship. (The appearance of an upper-bound expression that may evaluate to '?' shall be represented by an upper-bound relationship.)
