Field Detail activeFilters protected InputFilter[] activeFilters(Code) Active filters (in order). ascbuf protected char[] ascbuf(Code) Pointer to the US-ASCII header buffer. bodyBuffer protected byte[] bodyBuffer(Code) HTTP body buffer. buf protected byte[] buf(Code) Pointer to the current read buffer. filterLibrary protected InputFilter[] filterLibrary(Code) Filter library. Note: Filter[0] is always the "chunked" filter. headerBuffer protected char[] headerBuffer(Code) US-ASCII header buffer. headerBuffer1 protected byte[] headerBuffer1(Code) HTTP header buffer no 1. headerBuffer2 protected byte[] headerBuffer2(Code) HTTP header buffer no 2. headers protected MimeHeaders headers(Code) Headers of the associated request. inputStream protected InputStream inputStream(Code) Underlying input stream. inputStreamInputBuffer protected InputBuffer inputStreamInputBuffer(Code) Underlying input buffer. lastActiveFilter protected int lastActiveFilter(Code) Index of the last active filter. lastValid protected int lastValid(Code) Last valid byte. parsingHeader protected boolean parsingHeader(Code) State. pos protected int pos(Code) Position in the buffer. request protected Request request(Code) Associated Coyote request. sm protected static StringManager sm(Code) The string manager for this package. swallowInput protected boolean swallowInput(Code) Swallow input ? (in the case of an expectation) Constructor Detail InternalInputBuffer public InternalInputBuffer(Request request)(Code) Default constructor. InternalInputBuffer public InternalInputBuffer(Request request, int headerBufferSize)(Code) Alternate constructor. Method Detail addActiveFilter public void addActiveFilter(InputFilter filter)(Code) Add an input filter to the filter library. addFilter public void addFilter(InputFilter filter)(Code) Add an input filter to the filter library. clearFilters public void clearFilters()(Code) Clear filters. doRead public int doRead(ByteChunk chunk, Request req) throws IOException(Code) Read some bytes. endRequest public void endRequest() throws IOException(Code) End request (consumes leftover bytes). throws:   IOException - an undelying I/O error occured fill protected boolean fill() throws IOException(Code) Fill the internal buffer using data from the undelying input stream. false if at end of stream getFilters public InputFilter[] getFilters()(Code) Get filters. getInputStream public InputStream getInputStream()(Code) Get the underlying socket input stream. nextRequest public void nextRequest() throws IOException(Code) 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. parseHeader public boolean parseHeader() throws IOException(Code) Parse an HTTP header. false after reading a blank line (which indicates that theHTTP header parsing is done parseHeaders public void parseHeaders() throws IOException(Code) Parse the HTTP headers. parseRequestLine public void parseRequestLine() throws IOException(Code) Read the request line. This function is meant to be used during the HTTP request header parsing. Do NOT attempt to read the request body using it. throws:   IOException - If an exception occurs during the underlying socketread operations, or if the given buffer is not big enough to accomodatethe whole line. recycle public void recycle()(Code) Recycle the input buffer. This should be called when closing the connection. setInputStream public void setInputStream(InputStream inputStream)(Code) Set the underlying socket input stream. setSwallowInput public void setSwallowInput(boolean swallowInput)(Code) Set the swallow input flag.
