protected class |
TP.DefaultBundler
The sender's thread adds a message to the hashmap and - if the accumulated size has been exceeded - sends all
bundled messages.
|
protected class |

static class |
TP.ProtocolAdapter
Used when the transport is shared (singleton_name is not null).
|
protected class |
TP.TransferQueueBundler
This bundler adds all (unicast or multicast) messages to a queue until max size has been exceeded, but does send
messages immediately when no other messages are available.
