SIMediationSession

The SIMediationSession public interface defines the methods for querying and interacting with the service integration bus. As well as defining the methods for working with the service integration bus, this interface also includes methods that provide information about where the mediation is invoked from, and the criteria that are applied before the message is mediated.

Both selector and discriminator control which messages are sent to the mediation, through a rule specified in a text string. The rule specified by the selector examines the header and properties of the message, whereas the discriminator examines the topic of the message. If a message contains both selector and discriminator, it must match both rules for the message to be mediated. If either the selector or the discriminator rule does not match, the message is not mediated.

The API has these methods:
