public interface WatchedStream

Method Summary
`void`	`close()` In case we want to close a watchStream regardless of its making progress.
`void`	`setWatchList(Collection watchList)` Sets the watcher list onto which this stream must register when it is not idle (so that it can be watched).
`void`	`watch()` This routine may be invoked as often as progress needs to be asserted.

Method Detail

setWatchList

void setWatchList(Collection watchList)

Sets the watcher list onto which this stream must register when it is not idle (so that it can be watched). This implementation may or may not remain registered while idle. This may affect performance but not functionality. It is assumed that that list is monitored by a watcher task that invokes the watch method as often as needed to monitor progress to its satifaction.

Parameters:: watchList - The watchList to register with. Must be a Synchronized Collection.

watch

void watch()

This routine may be invoked as often as progress needs to be asserted. After at most two watch cycles stalling is detected.

close

void close()
           throws IOException

In case we want to close a watchStream regardless of its making progress.

Throws:: IOException
