Chapter 13 - Distinguishable Objects Ending-Distinguishable Types

Type 1 Type 2 How to define them as content-distinguishable

♦ 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 of the

first group is distinguishable from the initiator of the

second group, or

! The first group has an initiator, the second group has

no initiator and the first group is

content-distinguishable from the type of each

component of the second group, or

! The first group has no initiator the second group has

an initiator, and each component of the first group is

distinguishable from the second group, or

! Both types have initiators and the initiators are the

same or both types have no initiator, and the type of

each component of the first group is

content-distinguishable from the type of each

component of the second group.

group

The first component is either:

♦ A group marked as initiator-distinguishable and the

group is initiator-distinguishable from each partition of

the second type, or

♦ A group not marked as initiator-distinguishable and the

group is content-distinguishable from each partition of

the second type.

Ending-Distinguishable Types

Ending-distinguishability is used to determine if the end of a data object is

distinguishable from the start of any other data object that could be next in the

data.

The following table describes how two types may be ending-distinguishable. This is

helpful if you are validating data and you receive a message that says a type

exists, but it belongs to the wrong component.
