Interface IRuntimeContext

All Superinterfaces:

IAuditable, ILogger

All Known Implementing Classes:

RuntimeContext, RuntimeContext_new, RuntimeContextBase

public interface IRuntimeContext
extends IAuditable, ILogger

This interface defines methods and constants that are used during action execution to resolve parameters, inputs and outputs, resources, and persist the runtime data. Think of the runtime context as working storage for the execution of an action.
