Many Internet information-management applications (e.g., information integration systems) require a library of wrappers, specialized information extraction procedures that translate a source's native format into a structured representation suitable for further application-speci c processing. Maintaining wrappers is tedious and error-prone, because the formatting regularities on which wrappers r...

The use of Commercial Off-The-Shelf (COTS) software products as components of large-scale systems has become more and more pervasive. One of the interesting questions that has arisen is "Can you build secure applications using insecure components?" We have been investigating ways to protect data that is shared between two or more independent, insecure applications. Our initial attempts to accom...

A wrapper is a thin shell around the core, that provides the switching between functional, and core-internal and core-external test modes. Together with a test access mechanism (TAM), the core test wrapper forms the test access infrastructure to embedded reusable cores. Various company-internal as well as industry-wide standardized but scalable wrappers have been proposed. This paper deals with...

The purpose of this thesis project is to develop an XTM (XML Topic Maps) wrapper, called XTMWrapper, for the functional and object-oriented DBMS Amos II so that XTM files can be accessed through Amos II using its query language, AmosQL. The wrapper can be used as a database loader for XTM files. The wrapper parses XTM files, translates them into an Amos II data representation, and populates the...

The midline glia are specialized, nonneuronal cells at the midline of the Drosophila central nervous system (CNS). During development, the midline glia provide guidance cues for extending axons. At the same time, they migrate and help separate the two axon commissures. They then wrap around and ensheath the commissural axons. In many segments, a few of the glia do not enwrap the axons, and thes...

This paper describes the Wrapper Facade pattern. The intent of this pattern is to encapsulate low-level functions and data structures with object-oriented (OO) class interfaces. Common examples of the Wrapper Facade pattern are class libraries like MFC, ACE, and AWT that encapsulate native OS C APIs, such as sockets, pthreads, or GUI functions. Programming directly to native OS C APIs makes net...
