public interface Closeable
extends AutoCloseable

A Closeable is a source or destination of data that can be closed. The close method is invoked to release resources that the object is holding (such as open files).

Since:

1.5

Method Summary

Modifier and Type	Method	Description
void	close()	Closes this stream and releases any system resources associated with it.

Method Detail

close

void close()
    throws IOException

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

As noted in AutoCloseable.close(), cases where the close may fail require careful attention. It is strongly advised to relinquish the underlying resources and to internally mark the Closeable as closed, prior to throwing the IOException.

Specified by:

close in interface AutoCloseable

Throws:

IOException - if an I/O error occurs
