Method Details

enter

public final void enter()

exit

public final boolean exit()

Returns true if the timeout occurred.

timedOut

protected void timedOut()

Invoked by the watchdog thread when the time between calls to enter() and exit() has exceeded the timeout.

sink

public final Sink sink(Sink sink)

Returns a new sink that delegates to sink, using this to implement timeouts. This works best if timedOut() is overridden to interrupt sink's current operation.

source

public final Source source(Source source)

Returns a new source that delegates to source, using this to implement timeouts. This works best if timedOut() is overridden to interrupt sink's current operation.

newTimeoutException

protected IOException newTimeoutException(IOException cause)

Returns an IOException to represent a timeout. By default this method returns InterruptedIOException. If cause is non-null it is set as the cause of the returned exception.
