Ocean Modules
Ocean Modules
Extensions to the Product Family are implemented in independently loaded assemblies.
The .NET framework provides an environment in which Modules are loaded dynamically at
run time, relocated in memory, and connected to the Ocean Core by resolving unique
Namespace – Module name combinations.
Modules are referenced in the Petrel configuration file, which gets parsed when the Main
Petrel environment starts.
There is no limit to the number of Modules that can be loaded at startup time or later. This
system provides flexibility as well as rapid and robust deployment.
Fig. 2-6 Ocean Modules
Programmers create modules that behave just like any standard part of Petrel. The
modules are compiled into assemblies that are placed in the Petrel installation directory
and registered with the application through the configuration file. The assemblies are IL,
or Intermediate Language, code that is processor independent. It provides a common
layer, similar to assembly language, that all .NET languages (C#, C++, VB, etc.) compile
to. At runtime it is further compiled and executed by the .NET Common Language
Runtime, or CLR, engine.
