One object may refer to another object via the other object's ObjectID, a UINT32 value. Object IDs should be unique within a CDX/CDXML file, but in a case where there is ambiguity, a CDXObjectID refers to the closest object with that ID. For example, an object sharing the same containing object is closer than one that does not share the same containing object.
This data type is used if one object needs to refer to more than one other object. It is a series of UINT32 values. The length of the array is implicit from the size of the data.
Examples:
| CDX: | 01 00 00 00 02 00 00 00 03 00 00 00 04 00 00 00 |
| CDXML: | "1 2 3 4" |
This data type is used if one object needs to refer to more than one other object. It is a series of UINT32 values.
In CDX files, this data type lists the size of the array explicitly, unlike with the CDXObjectIDArray type, with an a leading UINT16 value before the series of CDXObjectIDs.
In CDXML files, this data type is equivalent to the CDXObjectIDArray type.
Examples:
| CDX: | 04 00 01 00 00 00 02 00 00 00 03 00 00 00 04 00 00 00 |
| CDXML: | "1 2 3 4" |
