Port
State Machines [2], an extension of UML 2.0 [3] State Machines
permitting to capture the interleaving and nesting of operation calls,
employ the trace semantics and compliance relation of Behavior
Protocols [1] to reason on component substitutability.
The key goal of this thesis is to make the Port State Machines more accessible for use in UML tools by employing the Object Constraint Language (OCL) [4] to express the compliance relation. An additional goal is to also express in OCL the various constraints imposed on Port State Machines.
These goals have been achieved and implemented using the Object Constraint Language Environment (OCLE) 2.0, developed in the Computer Science Research Laboratory at the Babes-Bolyai University.
The thesis has been successfully defended on Sep 20, 2005, and is now publicly accessible and available for download.
