Class DeviceLogIterator

java.lang.Object
  org.mbari.siam.core.DeviceLogIterator

All Implemented Interfaces:

java.util.Iterator

public class DeviceLogIterator
extends java.lang.Object
implements java.util.Iterator

DeviceLogIterator iterates over DevicePackets stored in a DeviceLog. NOTE: This implementation is not thread-safe!

Author:

Tom O'Reilly

Constructor Summary

DeviceLogIterator(DeviceLog log)
Create iterator, passing in DeviceLog on which to iterate.

DeviceLogIterator(DeviceLog log, long start)
Create iterator, passing in DeviceLog on which to iterate and specify a start time so that a binary search can be done (by getEntryIndex) to quickly find the first record.

Method Summary

boolean	hasNext() Returns true if DeviceLog has more packets.
java.lang.Object	next() Returns next DevicePacket from DeviceLog.
void	remove() Not supported.
