Field Detail

sm

protected static final StringManager sm

The string manager for this package.

request

protected Request request

Associated Coyote request.

headers

protected MimeHeaders headers

Headers of the associated request.

parsingHeader

protected boolean parsingHeader

State.

swallowInput

protected boolean swallowInput

Swallow input ? (in the case of an expectation)

buf

protected byte[] buf

Pointer to the current read buffer.

lastValid

protected int lastValid

Last valid byte.

pos

protected int pos

Position in the buffer.

end

protected int end

Pos of the end of the header in the buffer, which is also the start of the body.

inputStream

protected InputStream inputStream

Underlying input stream.

inputStreamInputBuffer

protected InputBuffer inputStreamInputBuffer

Underlying input buffer.

filterLibrary

protected InputFilter[] filterLibrary

Filter library. Note: Filter[0] is always the "chunked" filter.

Method Detail

parseRequestLine

public abstract boolean parseRequestLine(boolean useAvailableDataOnly)
                                  throws IOException

Throws:

IOException

parseHeaders

public abstract boolean parseHeaders()
                              throws IOException

Throws:

IOException

fill

protected abstract boolean fill(boolean block)
                         throws IOException

Throws:

IOException

setInputStream

public void setInputStream(InputStream inputStream)

Set the underlying socket input stream.

getInputStream

public InputStream getInputStream()

Get the underlying socket input stream.

addFilter

public void addFilter(InputFilter filter)

Add an input filter to the filter library.

getFilters

public InputFilter[] getFilters()

Get filters.

clearFilters

public void clearFilters()

Clear filters.

addActiveFilter

public void addActiveFilter(InputFilter filter)

Add an input filter to the filter library.

setSwallowInput

public void setSwallowInput(boolean swallowInput)

Set the swallow input flag.

recycle

public void recycle()

Recycle the input buffer. This should be called when closing the connection.

nextRequest

public void nextRequest()

End processing of current HTTP request. Note: All bytes of the current request should have been already consumed. This method only resets all the pointers so that we are ready to parse the next HTTP request.

endRequest

public void endRequest()
                throws IOException

End request (consumes leftover bytes).

Throws:

IOException - an underlying I/O error occurred

doRead

public int doRead(ByteChunk chunk,
                  Request req)
           throws IOException

Read some bytes.

Specified by:

doRead in interface InputBuffer

Throws:

IOException
