decorateWithCompression

public final OutputStream decorateWithCompression(OutputStream stream)
                                           throws IOException

Decorates the stream by wrapping it into a stream that applies a compression.

IMPORTANT: For streams returned by this method, OutputStream.close() is not propagated to the inner stream. The inner stream must be closed separately.

参数:

stream - the stream to decorate.

返回:

an output stream that is decorated by the compression scheme.

抛出:

IOException

decorateWithCompression

public final InputStream decorateWithCompression(InputStream stream)
                                          throws IOException

IMPORTANT: For streams returned by this method, InputStream.close() is not propagated to the inner stream. The inner stream must be closed separately.

参数:

stream - the stream to decorate.

返回:

an input stream that is decorated by the compression scheme.

抛出:

IOException

decorateWithCompression

protected abstract OutputStream decorateWithCompression(NonClosingOutputStreamDecorator stream)
                                                 throws IOException

参数:

stream - the stream to decorate

返回:

an output stream that is decorated by the compression scheme.

抛出:

IOException

decorateWithCompression

protected abstract InputStream decorateWithCompression(NonClosingInputStreamDecorator stream)
                                                throws IOException

参数:

stream - the stream to decorate.

返回:

an input stream that is decorated by the compression scheme.

抛出:

IOException
