Detailed Description

Interface that represents a container operation.

Examples of container operations are: Add an element to the end of the container, insert an element at a given position in the container, remove an element from the container, remove elements from the container that have a subject matching a specified prefix.

You add operations to a container message by calling the appropriate methods of IContainerMessage, such as IContainerMessage.AddElement or IContainerMessage.RemoveElement.

You can obtain the operations defined in a IContainerMessage by calling the IContainerMessage.Operations property.
