CLR Object Similarities¶

The Jetfire workflow object is modeled after the .net C# CLR object. It shares these features in common with a .net C# CLR object:

Fields
Methods
Constructor
Properties

Additional Features¶

In addition the Jetfire object has these features.

Workflow States
Persistent
- Workflow objects are stored in a server nexus.
- Each workflow has a GUID supporting retrieval and tracking.
- Is automatically serialized to permanent storage.
- Upon start up workflow objects are automatically restored to client nexus.
Bound to source code
Source code is interpreted and dynamically linked to other source code.
Code is represented as objects.
Dynamic access modifiers
- Changes dynamically based on an optional 'access' or 'states' construct.
The same workflow object can exist in multiple clients simultaneously.
- The server nexus is responsible for synchronizing updates.

Differences between Jetfire and CLR Objects¶

Difference between a C# object and a Jetfire workflow object

C#
- Source code is compiled and linked to other libraries
- Static access modifiers - private, protected, internal and public
