Class StandardEventsReader

java.lang.Object

input.StandardEventsReader

All Implemented Interfaces:

ExternalEventsReader

public class StandardEventsReader
extends java.lang.Object
implements ExternalEventsReader

External events reader for standard-format events (created e.g by the dtnsim2parser).

Syntax:
<time> <actionId> <msgId> <hostId> [<host2Id> [<size>] [<respSize>]]

All actions (except CONNECTION) must have first four fields. SEND, DELIVERED and ABORT actions need host2Id field too (the host who the message is/was being transferred to). CREATE action needs the additional size (of the message) field and can have also size-of-the-response field if a response to this message is requested.

CONNNECTION action is followed by the two hosts which connect (or disconnect) to each other and then either "up" or "down" depending on whether the connection was created or destroyed.

Message DROP and REMOVE events can use "*" as the message ID for referring to all messages the node has in message buffer (i.e., to delete all messages).
