CX_SECURITY_SET - Access group

CX_SECURITY_SET

Class hierarchy

Description: (Business Pattern)

Objects of this class are used to combine objects of the classes CX_CLASS_SECURITY, CX_OBJECT_SECURITY and CX_MESSAGE_SECURITY as well as other CX_SECURITY_SET objects.

CX_SECURITY_SET is intended as a summary of security objects that combine access rights into a group of access rights. The CX_SECURITY_SETs can be nested within each other as desired.

If multiple security objects define access rights for an object/message/class/system function, the override semantics apply and the last object defines the access. The access rights are not additive!

Example:

There are classes A, A1, A2 and B. A1 and A2 are derived from A, while B is independent of A:

Access to objects of classes A, A1 and B are defined with CX_CLASS_SECURITY objects. For some instances of A1, different rights are to apply (CX_OBJECT_SECURITY). Possibilities to realise this are

• Only the security objects for classes A and B are in the security set. The general specification for class A is subordinated to the specialisation for the derived class A1 and the CX_OBJECT_SECURITY object is subordinated to this:

• All security objects are directly assigned to the security set. The order of the security objects referring to A and A1 is essential.
  Attention: This behaviour has changed as of Dll version 225901.

Both variants are semantically equivalent.
