HttpOutputStream
public class HttpOutputStream extends ServletOutputStream (Code)
An output stream for writing servlet responses. This is an abstract class, to be implemented by a network services implementor. Servlet writers use the output stream to return data to clients. They access it via the ServletResponse's getOutputStream method, available from within the servlet's service method. Subclasses of ServletOutputStream must provide an implementation of the write(int) method.

This implementation is friendly to servlets which return "small" responses and don't compute Content-Length -- it will compute this header for them automatically.

Field Detail
autoFlush
boolean autoFlush(Code)



bos
ByteArrayOutputStream bos(Code)



bufferSize
int bufferSize(Code)



committed
boolean committed(Code)



os
WorkerOutputStream os(Code)



res
HttpResponse res(Code)





Method Detail
close
final public void close() throws IOException(Code)
Close does nothing, to prevent clients from closing streams when they really don't want to



discard
public boolean discard()(Code)
Discard any bytes written so far if possible, and return true if we were able to do so.



flush
final public void flush() throws IOException(Code)
Flush the underlying stream



flushBuffered
final public void flushBuffered() throws IOException(Code)
Flush any buffered output to tht client



getAutoFlush
final boolean getAutoFlush()(Code)



getBufferSize
final int getBufferSize()(Code)



getOutputStream
WorkerOutputStream getOutputStream()(Code)
Return the underlying output stream



getRemaining
public int getRemaining()(Code)



isCommitted
final boolean isCommitted()(Code)



reallyClose
final public void reallyClose() throws IOException(Code)



reset
public void reset(WorkerOutputStream os)(Code)
Construct a new http output stream, attached to the specified worker output stream.
Parameters:
  os - the output stream.



reset
final void reset() throws IllegalStateException(Code)



setAutoFlush
final void setAutoFlush(boolean autoFlush)(Code)



setBufferSize
final void setBufferSize(int size) throws IllegalStateException(Code)



setResponse
void setResponse(HttpResponse res)(Code)
Set up the connection with the http response object so we can control flushing the headers when we've reached our buffered limit.
Parameters:
  res - the http response object associated with this request



write
public void write(int b) throws IOException(Code)
Write a byte to the stream
Parameters:
  b - the byte



write
public void write(byte[] buf, int off, int len) throws IOException(Code)
Write a bunch of bytes in one shot.
Parameters:
  buf - a buffer where those bytes live
Parameters:
  off - the position in the buffer of the first byte to write
Parameters:
  len - the number of bytes to write
exception:
  IOException - may be thrown
