Term: HttpShell

A JEE Filter that examines incoming HTTP POST requests for certain parameters that indicate required operations on the MeshObjectGraph.

The HttpShell may:

• create one or more new MeshObjects
• look up MeshObjects
• change Properties on MeshObjects
• bless or unbless MeshObjects
• delete MeshObjects
• relate or unrelate pairs of MeshObjects to/from each other
• bless or unbless Relationships between two MeshObjects

Because the HttpShell can perform all data manipulation operations on MeshObjects and the MeshObjectGraph, it acts like a shell in an operating system on the MeshObjects in a MeshBase.

The primary advantages of the HttpShell are:

• data manipulation can be expressed entirely in HTML, by setting the parameter values to which the HttpShell reacts.
• developers can avoid having to write special POST handlers in many circumstances.
