                            throws IOException

抛出:

IOException

方法详细资料

isClosed

public boolean isClosed()

从接口复制的说明: FileIOChannel

Checks whether the channel has been closed.

指定者:

isClosed 在接口中 FileIOChannel

指定者:

isClosed 在类中 AbstractFileIOChannel

返回:

True if the channel has been closed, false otherwise.

close

public void close()
           throws IOException

从接口复制的说明: 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.

指定者:

close 在接口中 FileIOChannel

指定者:

close 在类中 AbstractFileIOChannel

抛出:

IOException - Thrown, if an error occurred while waiting for pending requests.
