 | Equals(ISubscriptionParameters) |
Determines if this instance of ISubscriptionParameters is equal to another instance. This is
used for message optimisation.

restrict the updates that reach the INewsSubscriptionListener
associated with the subscription.

RemarksParameters are used to specify a filter which the Liberator will apply to determine whether a news headline update should be sent to the application. Typically filters can be used to retrieve news headlines relating to a particular company or topic.
To create an INewsSubscriptionParameters object, use one of the CreateNewsSubscriptionParameters() methods of IParametersFactory.
