Interface Processor

All Known Implementing Classes:
AbstractProcessor, AbstractProcessorLight, AjpProcessor, Http11Processor, UpgradeProcessorBase, UpgradeProcessorExternal, UpgradeProcessorInternal

public interface Processor
Common interface for processors of all protocols.
  • Method Details

    • process

      Process a connection. This is called whenever an event occurs (e.g. more data arrives) that allows processing to continue for a connection that is not currently being processed.
      socketWrapper - The connection to process
      status - The status of the connection that triggered this additional processing
      The state the caller should put the socket in when this method returns
      IOException - If an I/O error occurs during the processing of the request
    • getUpgradeToken

      UpgradeToken getUpgradeToken()
      Generate an upgrade token.
      An upgrade token encapsulating the information required to process the upgrade request
      IllegalStateException - if this is called on a Processor that does not support upgrading
    • isUpgrade

      boolean isUpgrade()
      true if the Processor is currently processing an upgrade request, otherwise false
    • isAsync

      boolean isAsync()
    • timeoutAsync

      void timeoutAsync(long now)
      Check this processor to see if the timeout has expired and process a timeout if that is that case.

      Note: The name of this method originated with the Servlet 3.0 asynchronous processing but evolved over time to represent a timeout that is triggered independently of the socket read/write timeouts.

      now - The time (as returned by System.currentTimeMillis() to use as the current time to determine whether the timeout has expired. If negative, the timeout will always be treated as ifq it has expired.
    • getRequest

      Request getRequest()
      The request associated with this processor.
    • recycle

      void recycle()
      Recycle the processor, ready for the next request which may be on the same connection or a different connection.
    • setSslSupport

      void setSslSupport(SSLSupport sslSupport)
      Set the SSL information for this HTTP connection.
      sslSupport - The SSL support object to use for this connection
    • getLeftoverInput

      ByteBuffer getLeftoverInput()
      Allows retrieving additional input during the upgrade process.
      leftover bytes
      IllegalStateException - if this is called on a Processor that does not support upgrading
    • pause

      void pause()
      Informs the processor that the underlying I/O layer has stopped accepting new connections. This is primarily intended to enable processors that use multiplexed connections to prevent further 'streams' being added to an existing multiplexed connection.
    • checkAsyncTimeoutGeneration

      boolean checkAsyncTimeoutGeneration()
      Check to see if the async generation (each cycle of async increments the generation of the AsyncStateMachine) is the same as the generation when the most recent async timeout was triggered. This is intended to be used to avoid unnecessary processing.
      true If the async generation has not changed since the async timeout was triggered
