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.

Returns:

number of bytes written

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
