Chapter 13 - Distinguishable Objects Content-Distinguishable Types
Type 1 Type 2 How to define them as content-distinguishable
group item The first component is either:
♦ A group marked as initiator distinguishable and
! The item has an initiator and the initiator value of
the group is distinguishable from the initiator value
of the item, or
! The second type has no initiator and the initiator
value of the first type is distinguishable from the
value of the second type.
♦ A group not marked as initiator distinguishable and
! The group has an initiator, the item has an initiator
and the initiator value of the group is distinguishable
from initiator value of the item, or
! The group has an initiator, the item does not, and
value of the initiator is distinguishable from value of
the item, or
! Both types have initiators and they are the same, or
both types have no initiator and each type in the
starting component set of the group is
content-distinguishable from the value of the second
item.
group group The first component is either:
♦ A group marked as initiator distinguishable, and
! Both groups are different partitions of the same
partitioned sub-tree, or
! The second type has an initiator and those initiators
are mutually exclusive, or
! The second type has no initiator and the first group
is initiator-distinguishable from each type in the
starting component set of the second group.
♦ A group not marked as initiator distinguishable, and
! Both groups are different partitions of the same
partitioned sub-tree, or
! Both groups have an initiator and the initiator value
of the first group is distinguishable from the initiator
value of the second group, or
! The first group has no initiator, the second group has
an initiator and the type of each component in the
starting component set of the first group is
