close back to summary

close	back to summary
public void close() throws IOException Overrides java.io.OutputStream.close. Implements java.io.Closeable.close. Doc from java.io.OutputStream.close. Closes this output stream and releases any system resources associated with this stream. The general contract of `close` is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened. Exceptions IOException: if an I/O error occurs.

public void close() throws IOException

Overrides java.io.OutputStream.close.

Implements java.io.Closeable.close.

Doc from java.io.OutputStream.close.

Closes this output stream and releases any system resources associated with this stream. The general contract of close is that it closes the output stream. A closed stream cannot perform output operations and cannot be reopened.

Exceptions

IOException:: if an I/O error occurs.

finish	back to summary

flush back to summary

public void flush() throws IOException

Overrides java.io.OutputStream.flush.

Implements java.io.Flushable.flush.

Doc from java.io.OutputStream.flush.

Flushes this output stream and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive.

Exceptions

IOException:: if an I/O error occurs.
