Class PermStructMbr

java.lang.Object

com.automation_pros.odva.cip.data.StructMember

com.automation_pros.odva.cip.data.PermStructMbr

All Implemented Interfaces:

PermissionedItem

public class PermStructMbr
extends StructMember
implements PermissionedItem

Permissions are relatively fine-grained in Logix applications. It is possible that a structure member might be readable or writable individually, but the structure as a whole not be. To effectively optimize access, successes should propagate inward, while failures propagate outward.

Inward propagation in this hierarchy is easy--the references are always present. Outward propagation from member to structure is also easy, as a StructMember's "lock" status is ownership by a StructDef. Omron structures do not have fine-grained permissions, but initialized "failures" in nested types need to propagate outward.
