public final Enum ActionCode

Callback for an async call to jakarta.servlet.AsyncContext#complete().

Callback for an async call to jakarta.servlet.AsyncContext#dispatch().

Callback to indicate the the actual dispatch has started and that the async state needs change.

Callback to trigger the error processing.

Callback to determine if async processing is in progress.

Call back to determine if async complete is in progress.

Callback to determine if async dispatch is in progress.

Callback to determine if async is in error.

Callback to determine if async dispatch is in progress.

Callback to determine if async is timing out.

Callback to trigger post processing. Typically only used during error handling to trigger essential processing that otherwise would be skipped.

Callback for an async call to jakarta.servlet.AsyncContext#start(Runnable).

Callback for an async call to jakarta.servlet.AsyncContext#setTimeout(long)

Callback for an async request.

Callback to trigger the processing of an async timeout.

Callback for getting the amount of available bytes.

A flush() operation originated by the client ( i.e. a flush() on the servlet output stream or writer, called by a servlet ). Argument is the Response.

A serious error occurred from which it is not possible to recover safely. Further attempts to write to the response should be ignored and the connection needs to be closed as soon as possible. This can also be used to forcibly close a connection if an error occurs after the response has been committed.

Hook called if swallowing request input should be disabled. Example: Cancel a large file upload.

Execute any non-blocking dispatches that have been registered via DISPATCH_READ or DISPATCH_WRITE. Typically required when the non-blocking listeners are configured on a thread where the processing wasn't triggered by a read or write event on the socket.

Indicates that the container needs to trigger a call to onDataAvailable() for the registered non-blocking read listener.

Indicates that the container needs to trigger a call to onWritePossible() for the registered non-blocking write listener.

Has the processor been placed into the error state? Note that the response may not have an appropriate error code set.

The processor may have been placed into an error state and some error states do not permit any further I/O. Is I/O currently allowed?

Is server push supported and allowed for the current request?

Are the request trailer fields ready to be read? Note that this returns true if it is known that request trailer fields are not supported so an empty collection of trailers can then be read.

Are HTTP trailer fields supported for the current response? Note that once an HTTP/1.1 response has been committed, it will no longer support trailer fields.

Indicator that Servlet is interested in being notified when data is available to be read.

Used with non-blocking writes to determine if a write is currently allowed (sets passed parameter to true) or not (sets passed parameter to false). If a write is not allowed then callback will be triggered at some future point when write becomes possible again.

Obtain the request identifier for this request as defined by the protocol in use. Note that some protocols do not define such an identifier. E.g. this will be Stream ID for HTTP/2.

Push a request on behalf of the client of the current request.

Callback for lazy evaluation - extract the remote host address.

Callback for lazy evaluation - extract the remote host name and address.

Callback for lazy evaluation - local address.

Callback for lazy evaluation - local address.

Callback for lazy evaluation - socket local port.

Callback for lazy evaluation - extract the connection peer address.

Callback for lazy evaluation - socket remote port.

Callback for setting FORM auth body replay

Callback for lazy evaluation - extract the SSL-related attributes including the client certificate if present.

Force a TLS re-handshake and make the resulting client certificate (if any) available as a request attribute.

Indicates if the request body has been fully read.

Obtain the servlet connection instance for the network connection supporting the current request.

Callback to trigger the HTTP upgrade process.
