@Deprecated
public class ABP
extends Protocol

Deprecated.

Mainly used as a design study of Pluscal / TLA+

Alternating Bit Protocol. Use without any UNICASTX protocol. Place it somewhere below NAKACKX. Provides reliable p2p unicasting. Design is in ./doc/design/ABP.txt

Constructor Detail

ABP

public ABP()

Deprecated.

Method Detail

init

public void init()
          throws java.lang.Exception

Deprecated.

Description copied from class: Protocol

Called after instance has been created (null constructor) and before protocol is started. Properties are already set. Other protocols are not yet connected and events cannot yet be sent.

Overrides:

init in class Protocol

Throws:

java.lang.Exception - Thrown if protocol cannot be initialized successfully. This will cause the ProtocolStack to fail, so the channel constructor will throw an exception

down

public java.lang.Object down(Event evt)

Deprecated.

Description copied from class: Protocol

An event is to be sent down the stack. A protocol 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 protocol may need to add a header to it (or do nothing at all) before sending it down the stack using down_prot.down().

Overrides:

down in class Protocol

down

public java.lang.Object down(Message msg)

Deprecated.

Description copied from class: Protocol

A message is sent down the stack. Protocols may examine the message and do something (e.g. add a header) with it before passing it down.

Overrides:

down in class Protocol

up

public java.lang.Object up(Message msg)

Deprecated.

Description copied from class: Protocol

A single message was received. Protocols may examine the message and do something (e.g. add a header) with it before passing it up.

Overrides:

up in class Protocol

getEntry

protected ABP.Entry getEntry(java.util.concurrent.ConcurrentMap<Address,ABP.Entry> map,
                             Address dest)

Deprecated.
