Class OutputArchiveMetaData.EntryOutputStream

java.lang.Object
  java.io.OutputStream
      de.schlichtherle.io.util.SynchronizedOutputStream
          de.schlichtherle.io.OutputArchiveMetaData.EntryOutputStream

All Implemented Interfaces:

Closeable, Flushable

Enclosing class:

OutputArchiveMetaData

private final class OutputArchiveMetaData.EntryOutputStream
extends SynchronizedOutputStream

An OutputStream to write the entry data to an OutputArchive. This output stream provides support for finalization and throws an IOException on any subsequent attempt to write data after OutputArchiveMetaData.closeAllOutputStreams(de.schlichtherle.io.ArchiveException) has been called.

void	close() Closes this archive entry stream and releases any resources associated with it.
protected void	doClose() Closes the underlying stream and marks this stream as being closed.
private void	ensureNotStopped()
protected void	finalize() The finalizer in this class forces this archive entry output stream to close.
void	flush() Synchronizes on the SynchronizedOutputStream.lock and calls SynchronizedOutputStream.doFlush().

Method Detail

ensureNotStopped

private final void ensureNotStopped()
                             throws IOException

Throws:

IOException

write

public void write(int b)
           throws IOException

Overrides:

write in class SynchronizedOutputStream

Throws:

IOException

write

public void write(byte[] b)
           throws IOException

Overrides:

write in class SynchronizedOutputStream

Throws:

IOException

write

public void write(byte[] b,
                  int off,
                  int len)
           throws IOException

Overrides:

write in class SynchronizedOutputStream

Throws:

IOException

flush

public void flush()
           throws IOException

Description copied from class: SynchronizedOutputStream

Synchronizes on the SynchronizedOutputStream.lock and calls SynchronizedOutputStream.doFlush().

Specified by:

flush in interface Flushable

Overrides:

flush in class SynchronizedOutputStream

Throws:

IOException

close

public final void close()
                 throws IOException

Closes this archive entry stream and releases any resources associated with it. This method tolerates multiple calls to it: Only the first invocation flushes and closes the underlying stream.

Specified by:

close in interface Closeable

Overrides:

close in class SynchronizedOutputStream

Throws:

IOException - If an I/O exception occurs.

doClose

protected void doClose()
                throws IOException

Closes the underlying stream and marks this stream as being closed. It is an error to call this method on an already closed stream. This method does not remove this stream from the pool. This method is not synchronized!

Overrides:

doClose in class SynchronizedOutputStream

Throws:

IOException - If an I/O exception occurs.

finalize

protected void finalize()
                 throws Throwable

The finalizer in this class forces this archive entry output stream to close. This is used to ensure that an archive can be updated although the client may have "forgot" to close this output stream before.

Overrides:

finalize in class Object

Throws:

Throwable
