Class ScriptableExecutionContext

java.lang.Object
  org.eclipse.vtp.framework.common.services.ScriptableExecutionContext

All Implemented Interfaces:

IScriptable

public class ScriptableExecutionContext
extends java.lang.Object
implements IScriptable

An IScriptable implementation that makes the IExecutionContext instance available as a scripting object.

This service will make available a "Execution" object to all scripts in its scope. The variable supports the following properties:

• id: a string containing the execution ID
• parameters: an object containing the execution parameters

The parameters object listed above will have a property for each execution parameter defined in the execution context. New parameters may be added by assigning to non-existent properties of the object. The parameters object will not have an implicit value.

The "Execution" scripting object uses the execution ID as the implicit value, thus it can be compared to other string objects.
