C# Class LCM.LCM.MessageAggregator

Accumulates received LCM messages in a queue.

{@link LCM} normally delivers messages asynchronously by invoking the {@link LCMSubscriber#messageReceived messageReceived} method on a subscriber as soon as a message is received. This class provides an alternate way to receive messages by storing them in an internal queue, and then delivering them to synchronously to the user.

The aggregator has configurable limits. If too many messages are aggregated without having been retrieved, then older messages are discarded.
