Package org.jgroups.protocols
Class PARTITION
java.lang.Object
org.jgroups.stack.Protocol
org.jgroups.protocols.PARTITION
Protocol to simulate a partition. This can be done in 2 ways: send down a PARTITION event (with a boolean flag on or
off, to start or end a partition), or by grabbing a reference to the protocol via the ProtocolStack and calling the
methods startPartition() or stopPartition() directly. This can also be done via JMX.
A partition simply discards all messages, but let's other events pass.

down
Description copied from class:Protocol
An event is to be sent down the stack. The layer may want to examine its type and perform some action on it, depending on the event's type. If the event is a message MSG, then the layer may need to add a header to it (or do nothing at all) before sending it down the stack usingdown_prot.down()
. In case of a GET_ADDRESS event (which tries to retrieve the stack's address from one of the bottom layers), the layer may need to send a new response event back up the stack usingup_prot.up()

up
Description copied from class:Protocol
An event was received from the layer below. Usually the current layer will want to examine the event type and - depending on its type - perform some computation (e.g. removing headers from a MSG event type, or updating the internal membership list when receiving a VIEW_CHANGE event). Finally the event is either a) discarded, or b) an event is sent down the stack usingdown_prot.down()
or c) the event (or another event) is sent up the stack usingup_prot.up()
.
