Method Details

isClosed

public boolean isClosed()

Description copied from interface: FileIOChannel

Checks whether the channel has been closed.

Specified by:

isClosed in interface FileIOChannel

Specified by:

isClosed in class AbstractFileIOChannel

Returns:

True if the channel has been closed, false otherwise.

close

public void close()
           throws IOException

Description copied from interface: FileIOChannel

Closes the channel. For asynchronous implementations, this method waits until all pending requests are handled. Even if an exception interrupts the closing, the underlying FileChannel is closed.

Specified by:
