TP.ProtocolAdapter

public TP.ProtocolAdapter(java.lang.String cluster_name,
                  java.lang.String transport_name,
                  Protocol up,
                  Protocol down,

                  Address addr)

Method Detail

getMembers

public java.util.List<Address> getMembers()

getThreadFactory

public ThreadFactory getThreadFactory()

Description copied from class: Protocol

Supposed to be overwritten by subclasses. Usually the transport returns a valid non-null thread factory, but thread factories can also be created by individual protocols

Overrides:

getThreadFactory in class Protocol

Returns:

down

public java.lang.Object down(Event evt)

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 using down_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 using up_prot.up().

Overrides:

down in class Protocol

up

public java.lang.Object up(Event evt)

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 using down_prot.down() or c) the event (or another event) is sent up the stack using up_prot.up().

Overrides:

up in class Protocol

getName

public java.lang.String getName()

Specified by:

getName in class Protocol

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
