public interface InputBuffer
This class is only for internal use in the protocol implementation. All reading from Tomcat (or adapter) should be done using Request.doRead().

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    available()
    Obtain an estimate of the number of bytes that can be read without blocking.
    int
    doRead(ApplicationBufferHandler handler)
    Read from the input stream into the ByteBuffer provided by the ApplicationBufferHandler.

  • Method Details

    • doRead

      int doRead(ApplicationBufferHandler handler) throws IOException
      Read from the input stream into the ByteBuffer provided by the ApplicationBufferHandler. IMPORTANT: the current model assumes that the protocol will 'own' the ByteBuffer and return a pointer to it.
      Parameters:
      handler - ApplicationBufferHandler that provides the buffer to read data into.
      Returns:
      The number of bytes that have been added to the buffer or -1 for end of stream
      Throws:
      IOException - If an I/O error occurs reading from the input stream

    • available

      int available()
      Obtain an estimate of the number of bytes that can be read without blocking. Typically, this will be the number of available bytes known to be buffered.
      Returns:
      The number of bytes that can be read without blocking
