Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`boolean`	`continueMatching()`	Returns true if the selector should still keep searching for further matches.
`long`	`getExpiration()`	Returns the # of milliseconds since the epoch after which this selector should stop searching for matches.
`boolean`	`isMatch(I2NPMessage message)`	Returns true if the received message matches the selector.

- Method Detail
  - isMatch
```
boolean isMatch(I2NPMessage message)
```
    Returns true if the received message matches the selector. If this returns true, the job specified by OutNetMessage.getOnReplyJob() will be run for every OutNetMessage associated with this selector (by InNetMessagePool), after calling setMessage() for that ReplyJob. WARNING this is called from within OutboundMessageSelector.getOriginalMessages() inside a lock and can lead to deadlocks if the selector does too much in isMatch(). Until the lock is removed, take care to keep it simple.
  - continueMatching
```
boolean continueMatching()
```
    Returns true if the selector should still keep searching for further matches. This is called only if isMatch() returns true. If this returns true, isMatch() will not be called again.
  - getExpiration
```
long getExpiration()
```
    Returns the # of milliseconds since the epoch after which this selector should stop searching for matches. At some time after expiration, if continueMatching() has not returned false, the job specified by OutNetMessage.getOnFailedReplyJob() will be run for every OutNetMessage associated with this selector (by OutboundMessageRegistry).
