CTX_Structure - Structure Context

Inherits:  CTX_DBBase

A structure context is created for each structure type. It defines the connection between the instance and the instance description. Moreover, it allows determining the active context hierarchy for the structure instance, i.e. the parent property/extent, the structure the parent property is defined in, the parent parent property etc. Thus, the structure context defines the context in which the object instance has been provided.

The parent context for a structure context is always a property context. This can be the property context for an extent or for another property within a structure instance.

The structure context allows handling read and updating events as well as creating or deleting events.
