public class HttpOutputStream

extends ServletOutputStream

buf

The output buffer.

committed

Indicated whether the buffer has been written to the stream

count

The current number of bytes in the buffer.

except

If set then an I/O exception is pending.

length

The content length for this stream.

limit

The maximum number of bytes that can be written.

obs

The observer that will be notified when the stream is first written.

out

The actual output stream.

total

The total number of bytes written so far.

HttpOutputStream()

Creates a new, uninitialized servlet output stream with a default buffer size.

HttpOutputStream(int)

Creates a new servlet output stream using the specified buffer size.

check(int)

Checks the output stream for a pending IOException that needs to be thrown, a content length that has been exceeded, or observers that need to be notified.

close()

Closes the servlet output stream.

finish()

Finishes the current response.

flush()

Flushes the output stream.

flushBytes()

Flushes the output stream bytes.

getContentLength()

Returns the content length for this output stream, or -1 if not set.

getTotal()

Returns the total number of bytes written so far.

init(OutputStream)

Initializes the output stream with the specified raw output stream.

isCommitted()

Returns whether the output has been committed or not.

next()

Begins the next response.

print(HttpDate)

Prints an HttpDate object.

print(String)

Prints a string.

resets()

Resets the output stream for a new connection.

setContentLength(int)

Sets the content length for this output stream.

setHeader(byte[])

setHeader(byte[], int, int)

setIOException(IOException)

Sets the pending IOException for this output stream.

setObserver(Observer)

Sets an observer for this output stream.

write(byte[], int, int)

Writes an array of bytes.

write(int)

Writes a byte.

writeOut(byte[], int, int)

 protected OutputStream out

The actual output stream.

 protected byte buf[]

The output buffer.

 protected int count

The current number of bytes in the buffer.

 protected int total

The total number of bytes written so far.

 protected int limit

The maximum number of bytes that can be written. This is initially set to -1 in order to indicate that observers must be notified.

 protected int length

The content length for this stream.

 protected Observer obs

The observer that will be notified when the stream is first written.

 protected IOException except

If set then an I/O exception is pending.

 protected boolean committed

Indicated whether the buffer has been written to the stream

 public HttpOutputStream(int size)

Creates a new servlet output stream using the specified buffer size.

Parameters:

size - the output buffer size

 public HttpOutputStream()

Creates a new, uninitialized servlet output stream with a default buffer size.

 public void init(OutputStream out) throws IOException

Initializes the output stream with the specified raw output stream.

Parameters:

out - the raw output stream

 public void next()

Begins the next response.

 public void finish() throws IOException

Finishes the current response.

 public void resets()

Resets the output stream for a new connection.

 public int getTotal()

Returns the total number of bytes written so far.

 public void setContentLength(int len)

Sets the content length for this output stream.

Parameters:

len - the content length

 public int getContentLength()

Returns the content length for this output stream, or -1 if not set.

 public void setObserver(Observer obs)

Sets an observer for this output stream. The observer will be notified when the stream is first written to.

 public void setIOException(IOException e)

Sets the pending IOException for this output stream.

Parameters:

e - the IOException

 public boolean isCommitted()

Returns whether the output has been committed or not.

 protected void check(int len) throws IOException

Checks the output stream for a pending IOException that needs to be thrown, a content length that has been exceeded, or observers that need to be notified.

Parameters:

len - the number of bytes about to be written

 public void write(int b) throws IOException

Writes a byte. This method will block until the byte is actually written.

Parameters:

b - the byte

Throws: IOException

if an I/O error has occurred

Overrides:

write in class OutputStream

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

Writes an array of bytes. This method will block until all the bytes are actually written.

Parameters:

b - the data to be written

off - the start offset of the data

len - the number of bytes to write

Throws: IOException

if an I/O error has occurred

Overrides:

write in class OutputStream

 public void flush() throws IOException

Flushes the output stream.

Overrides:

flush in class OutputStream

 protected void flushBytes() throws IOException

Flushes the output stream bytes.

 public void print(String s) throws IOException

Prints a string.

Throws: IOException

if an I/O error has occurred

Overrides:

print in class ServletOutputStream

 public void print(HttpDate d) throws IOException

Prints an HttpDate object.

 public void close() throws IOException

Closes the servlet output stream.

Overrides:

close in class OutputStream

 public void setHeader(byte buf[]) throws IOException

 public void setHeader(byte buf[],
                       int offset,
                       int len) throws IOException

 protected void writeOut(byte buf[],
                         int offset,
                         int len) throws IOException
