Enumerations

Icon	Type	Description
	DataStatus	Defines the possible states of the data in a subscription.
	ISubscription	Represents a subscription to a subject on the Liberator.
	ISubscriptionDataEvent	Defines the interface from which all subject-type specific interfaces are descendent
	ISubscriptionErrorEvent	Represents an event raised when there is an error in a subscription.
	ISubscriptionListener	The ISubscriptionListener interface allows applications to receive events raised for a subscription: error events (ISubscriptionErrorEvent) and status change events (ISubscriptionStatusEvent). For each type of subscription you must define a class that implements a listener for events that can be raised on the subscription type. For example, events relating to record subscriptions ([!:StreamLink.Subscription.Record.IRecordSubscription]) are handled by an implementation of [!:StreamLink.Subscription.Record.IRecordSubscriptionListener]. The various subscription listeners all inherit from ISubscriptionListener, so they must implement the callback methods defined here.

	ISubscriptionParameters	The parameters relating to a subscription (ISubscription) on Liberator.
	ISubscriptionStatusEvent	Represents an event raised when there is a change in the status of a subscription.
	SubscriptionError	Identifies the type of a subscription related error.
	SubscriptionEventType	Indicates what type of ISubscriptionDataEvent has occurred.
	SubscriptionStatus	Indicates the status of a subscription.
	SubscriptionStatusEventType	Indicates the type of an event (ISubscriptionStatusEvent) that is raised when there is a change in the status of a subscription.

Remarks

Defines base interfaces for all subscriptions, subscription listeners and events. Event types include ISubscriptionDataEvent, ISubscriptionStatusEvent, and ISubscriptionErrorEvent. Also defines standard status enums such as DataStatus, SubscriptionStatus, SubscriptionStatusEventType, and SubscriptionError.
