Class MessageBuffer<T>

java.lang.Object

net.tomp2p.relay.buffer.MessageBuffer<T>

extends Object

Buffers messages for the unreachable peers. This class is thread-safe. If the buffer is full, the MessageBufferListeners are triggered. In the mean time, another list holds the previously buffered messages, until the buffer is collected.
