Method Detail

GetName

public java.lang.String GetName()

Overrides:

GetName in class Protocol

Up

public void 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 PassDown or c) the event (or another event) is sent up the stack using PassUp.

Overrides:

Up in class Protocol

Down

public void 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 PassDown. 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 PassUp.

Overrides:

Down in class Protocol

Reset

public void Reset()

Description copied from class: Protocol

Used when new member joins (new stack needs to start from a defined point), typically just resetting its state. For example, a sliding window protocol used for negative acknowledgement would reset its lower mark to 0 again.

Overrides:

Reset in class Protocol

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
