Parameters

reuse	whether the connection should be re-used

Member Function Documentation

eofDetected()

boolean eofDetected

(

InputStream

wrapped

)

throws IOException

Parameters

wrapped

the underlying stream which has reached EOF

Returns

true if wrapped should be closed, false if it should be left alone

Exceptions

IOException

in case of an IO problem, for example if the watcher itself closes the underlying stream. The caller will leave the wrapped stream alone, as if false was returned.

Implements EofSensorWatcher.

streamClosed()

boolean streamClosed

(

InputStream

wrapped

)

throws IOException

This method will be called only if EOF was not detected before closing. Otherwise, eofDetected is called.

Parameters

wrapped

the underlying stream which has not reached EOF

Returns

true if wrapped should be closed, false if it should be left alone

Exceptions

IOException

in case of an IO problem, for example if the watcher itself closes the underlying stream. The caller will leave the wrapped stream alone, as if false was returned.

Implements EofSensorWatcher.

streamAbort()

boolean streamAbort

(

InputStream

wrapped

)

throws IOException

This method will be called only if EOF was not detected before aborting. Otherwise, eofDetected is called.

This method will also be invoked when an input operation causes an IOException to be thrown to make sure the input stream gets shut down.

Parameters

wrapped

the underlying stream which has not reached EOF

Returns

true if wrapped should be closed, false if it should be left alone

Exceptions

IOException

in case of an IO problem, for example if the watcher itself closes the underlying stream. The caller will leave the wrapped stream alone, as if false was returned.

Implements EofSensorWatcher.
