|

1097 * number of technical difficulties related to interruptible IO that

|

1099 * InterruptedIOExceptions specially, they simply treat those as any
|
|
|
1100 * IOExceptions, which typically indicate fatal errors.
|
|
|
1101 *
|
|
|
1102 * There are also two modes of operation for interruptible IO. In the
|
|
|
1103 * resumption mode, an interrupted IO operation is guaranteed not to
|
|
|
1104 * have any side-effects, and can be restarted. In the termination mode,
|
|
|
1105 * an interrupted IO operation corrupts the underlying IO stream, so
|
|
|
1106 * that the only reasonable operation on an interrupted stream is to
|
|
|
1107 * close that stream. The resumption mode seems to be impossible to
|
|
|
1108 * implement on Win32 and Solaris. Implementing the termination mode is
|
|
|
1109 * easier, but it's not clear that's the right semantics.
|
|
|
1110 *
|
|
|
1111 * Interruptible IO is not supported on Win32.It can be enabled/disabled
|
|
|
1112 * using a compile-time flag on Solaris. Third-party JVM ports do not
|
|
