Detailed Description

A factory for creating FilterExpressions for use in the IContainerSubscriptionParameters select method.

IContainerSubscriptionParameters containerSubscriptionParameters = streamlink.CreateContainerSubscriptionParameters();

IFilterExpression fe1 = ContainerFilterFactory.Create("BestBid", FilterExpressionOperator.GREATER_THAN, "100");
IFilterExpression fe2 = ContainerFilterFactory.Create("BestAsk", FilterExpressionOperator.LESS_THAN, "300");
IFilterExpression fe3 = ContainerFilterFactory.CreateLogical(FilterExpressionLogicalOperator.AND, fe1, fe2);

containerSubscriptionParameters.Select(fe3.ToFilterString(), null, null);

ISubscription subscription = streamlink.Subscribe("/container", subscriptionListener, containerSubscriptionParameters);
