public class InternalOutputBuffer
Output buffer.
| Nested Class Summary | |
|---|---|
| protected  class | InternalOutputBuffer.OutputStreamOutputBufferThis class is an output buffer which will write data to an output stream. | 
| Field Summary | |
|---|---|
| protected  OutputFilter[] | activeFiltersActive filter (which is actually the top of the pipeline). | 
| protected  byte[] | bufThe buffer used for header composition. | 
| protected  boolean | committedCommitted flag. | 
| protected  OutputFilter[] | filterLibraryFilter library. | 
| protected  boolean | finishedFinished flag. | 
| protected  MimeHeaders | headersHeaders of the associated request. | 
| protected  int | lastActiveFilterIndex of the last active filter. | 
| protected  java.io.OutputStream | outputStreamUnderlying output stream. | 
| protected  OutputBuffer | outputStreamOutputBufferUnderlying output buffer. | 
| protected  int | posPosition in the buffer. | 
| protected  Response | responseAssociated Coyote response. | 
| protected static StringManager | smThe string manager for this package. | 
| protected  ByteChunk | socketBufferSocket buffer. | 
| protected  boolean | useSocketBufferSocket buffer (extra buffering to reduce number of packets sent). | 
| Constructor Summary | |
|---|---|
| InternalOutputBuffer(Response response)Default constructor. | |
| InternalOutputBuffer(Response response,
                     int headerBufferSize)Alternate constructor. | |
| Method Summary | |
|---|---|
|  void | addActiveFilter(OutputFilter filter)Add an output filter to the filter library. | 
|  void | addFilter(OutputFilter filter)Add an output filter to the filter library. | 
|  void | clearFilters()Clear filters. | 
| protected  void | commit()Commit the response. | 
|  int | doWrite(ByteChunk chunk,
        Response res)Write the contents of a byte chunk. | 
|  void | endHeaders()End the header block. | 
|  void | endRequest()End request. | 
|  void | flush()Flush the response. | 
|  OutputFilter[] | getFilters()Get filters. | 
|  java.io.OutputStream | getOutputStream()Get the underlying socket output stream. | 
|  void | nextRequest()End processing of current HTTP request. | 
|  void | realWriteBytes(byte[] cbuf,
               int off,
               int len)Callback to write data from the buffer. | 
|  void | recycle()Recycle the output buffer. |

|  void | setOutputStream(java.io.OutputStream outputStream)Set the underlying socket output stream. | 
|  void | setSocketBuffer(int socketBufferSize)Set the socket buffer size. | 
|  void | write(byte[] b)This method will write the contents of the specyfied byte buffer to the output stream, without filtering. | 
| protected  void | write(ByteChunk bc)This method will write the contents of the specyfied message bytes buffer to the output stream, without filtering. | 
| protected  void | write(CharChunk cc)This method will write the contents of the specyfied char buffer to the output stream, without filtering. |
