Constructor Detail

### JkInputStream

    public JkInputStream(MsgContext context,
                         int bsize)

### JkInputStream

    public JkInputStream(MsgContext context)

  Deprecated.

Method Detail

### setIsReadRequired

    public void setIsReadRequired(boolean irr)

  Set the flag saying that the server is sending a body

### isReadRequired

    public boolean isReadRequired()

  Return the flag saying that the server is sending a body

### recycle

    public void recycle()

  Must be called before or after each request

### endMessage

    public void endMessage()
                    throws java.io.IOException

  Throws:
    `java.io.IOException`

### doWrite

    public int doWrite(ByteChunk chunk,
                       Response res)
                throws java.io.IOException

  Description copied from interface: `OutputBuffer`
  Write the response. The caller ( tomcat ) owns the chunks.

  Specified by:
    `doWrite` in interface `OutputBuffer`
  Parameters:
    `chunk` - data to write
    `res` - used to allow buffers that can be shared by multiple responses.
  Throws:
    `java.io.IOException`

### doRead

    public int doRead(ByteChunk responseChunk,
                      Request req)
               throws java.io.IOException

  Description copied from interface: `InputBuffer`
  Return from the input stream. IMPORTANT: the current model assumes that the protocol will 'own' the buffer and return a pointer to it in ByteChunk ( i.e. the param will have chunk.getBytes()==null before call, and the result after the call ).

  Specified by:
    `doRead` in interface `InputBuffer`
  Throws:
    `java.io.IOException`

### receive

    public boolean receive()
                    throws java.io.IOException

  Receive a chunk of data. Called to implement the 'special' packet in ajp13 and to receive the data after we send a GET_BODY packet

  Throws:
    `java.io.IOException`

### appendHead

    public void appendHead(Response res)
                    throws java.io.IOException

  Throws:
    `java.io.IOException`

### setReplay

    public void setReplay(ByteChunk replay)

  Set the replay buffer for Form auth
