| Field Summary | |
| protected byte[] | buffer
The buffer through which all of our output bytes are passed. | | protected int | bufferCount
The number of data bytes currently in the buffer. | | protected boolean | closed
| | protected int | compressionThreshold
The threshold number which decides to compress or not. | | protected GZIPOutputStream | gzipstream
The underlying gzip output stream to which we should write data. | | protected int | length
The content length past which we will not write, or -1 if there is
no defined content length. | | protected ServletOutputStream | output
The underlying servket output stream to which we should write data. | | protected HttpServletResponse | response
The response with which this servlet output stream is associated. |
| Method Summary | |
| public void | close()
Close this output stream, causing any buffered data to be flushed and
any further output data to throw an IOException. | | public boolean | closed()
| | public void | flush()
Flush any buffered data for this output stream, which also causes the
response to be committed. | | public void | flushToGZip()
| | protected void | setBuffer(int threshold)
| | public void | setDebugLevel(int debug)
| | public void | write(int b)
Write the specified byte to our output stream. | | public void | write(byte b)
Write b.length bytes from the specified byte array
to our output stream. | | public void | write(byte b, int off, int len)
Write len bytes from the specified byte array, starting
at the specified offset, to our output stream. | | public void | writeToGZip(byte b, int off, int len)
|
| buffer | | protected byte[] buffer(Code) | | The buffer through which all of our output bytes are passed.
|
| bufferCount | | protected int bufferCount(Code) | | The number of data bytes currently in the buffer.
|
| closed | | protected boolean closed(Code) | | Has this stream been closed?
|
| compressionThreshold | | protected int compressionThreshold(Code) | | The threshold number which decides to compress or not.
Users can configure in web.xml to set it to fit their needs.
|
| gzipstream | | protected GZIPOutputStream gzipstream(Code) | | The underlying gzip output stream to which we should write data.
|
| length | | protected int length(Code) | | The content length past which we will not write, or -1 if there is
no defined content length.
|
| CompressionResponseStream | | public CompressionResponseStream(HttpServletResponse response) throws IOException(Code) | | Construct a servlet output stream associated with the specified Response.
Parameters:
response - The associated response |
| close | | public void close() throws IOException(Code) | | Close this output stream, causing any buffered data to be flushed and
any further output data to throw an IOException.
|
| closed | | public boolean closed()(Code) | | Has this response stream been closed?
|
| flush | | public void flush() throws IOException(Code) | | Flush any buffered data for this output stream, which also causes the
response to be committed.
|
| setBuffer | | protected void setBuffer(int threshold)(Code) | | Set the compressionThreshold number and create buffer for this size
|
| setDebugLevel | | public void setDebugLevel(int debug)(Code) | | Set debug level
|
| write | | public void write(int b) throws IOException(Code) | | Write the specified byte to our output stream.
Parameters:
b - The byte to be written
exception:
IOException - if an input/output error occurs |
| write | | public void write(byte b) throws IOException(Code) | | Write b.length bytes from the specified byte array
to our output stream.
Parameters:
b - The byte array to be written
exception:
IOException - if an input/output error occurs |
| write | | public void write(byte b, int off, int len) throws IOException(Code) | | Write len bytes from the specified byte array, starting
at the specified offset, to our output stream.
Parameters:
b - The byte array containing the bytes to be written
Parameters:
off - Zero-relative starting offset of the bytes to be written
Parameters:
len - The number of bytes to be written
exception:
IOException - if an input/output error occurs |
| writeToGZip | | public void writeToGZip(byte b, int off, int len) throws IOException(Code) | | |
