around BUILDARGS

    (ClassName $class: @args)

BUILDARGS is wrapped to translate from the expected Plack::Handler interface to POEx::Role::TCPServer's expected interface.

psgi_app

    is: ro, isa: CodeRef, writer: register_service

This attribute stores the PSGI application to be run from this server. A writer method is provided to match the expected Plack::Handler interface

wheel_flushers

    is: ro, isa: HashRef,
    exists : has_wheel_flusher,
    get    : get_wheel_flusher,
    set    : set_wheel_flusher,
    delete : clear_wheel_flusher

This attribute stores coderefs to be called on a wheel's flush event (necessary to properly handle poll_cb)

run

    (CodeRef $app)

run is provided to complete the Plack::Handler interface and allow the server to be executed with the provided psgi app

after _start

    is Event

_start is advised to supply the proper input (HTTP::Parser) and output (Stream) filters.

write

    (PSGIServerContext $c, Str $data)

write will alter the data if necessary for a chunked transfer encoded response and send it to the output buffer for the current context

close

    (PSGIServerContext $c)

close will close the connection for the current context, but flushing the output buffer first

handle_socket_error

    (Str $action, Int $code, Str $message, WheelID $id) is Event

handle_socket_error overridden from POEx::Role::TCPServer to delete the wheel when a socket level error happens. If more intelligent actions are required, please feel free to exclude this method and provide your own implementation

handle_listen_error

    (Str $action, Int $code, Str $message, WheelID $id) is Event

handle_listen_error is overridden from POEx::Role::TCPServer to die when the SocketFactory fails to listen to the provided address/port. If more intelligent actions are required, please feel free to exclude this method and provide your own implementation

process_headers

    (PSGIServerContext $c, PSGIResponse $response)

process_headers takes the headers from the PSGIResponse, and sends it to the output buffer for the current context. This method also determines if the response body should be transfer encoded as chunked based on the Connection and Content-Length headers.

http_preamble

    (PSGIServerContext $c, PSGIResponse $response)

http_preamble sends the first line of the HTTP response to the output buffer of the current context

http_body_allowed

    (PSGIServerContext $c, PSGIResponse $response) returns (Bool)

http_body_allowed checks the result code from the PSGIResponse to determine if a body should be allowed to be returned. Returns true if a body is allowed, false otherwise.

respond

    (PSGIServerContext $c, PSGIResponse $response) is Event

respond processes the PSGIResponse to write out a valid HTTP response. If the body of the response is a real filehandle, it will be streamed appropriately via POEx::Role::PSGIServer::Streamer. If not, it will be iterated with which ever appropriate interface to the output buffer. If no body is provided, "generate_push_writer" is called to generate an appropriate object for use in push responses.

generate_push_writer

    (PSGIServerContext $c) returns (Object)

generate_push_writer by default constructs and returns a POEx::Role::PSGIServer::ProxyWriter object that implements the push-object interface defined in PSGI

generate_psgi_env

    (PSGIServerContext $c) returns (HashRef)

generate_psgi_env returns a suitable HashRef as defined by PSGI for application use. If additional application specific items need to be added to the hash, please feel free to advise this method

build_server_context

    (HTTPRequest $req, WheelID $wheel_id) returns (PSGIServerContext)

build_server_context constructs and returns a "PSGIServerContext" in POEx::Types::PSGIServer for the current connection

handle_inbound_data

    (HTTPRequest $req, WheelID $wheel_id) is Event

handle_inbound_data implements the required method for POEx::Role::TCPServer. It builds a server context, generates a psgi env hash, runs the psgi app, and then responds to the client

_write

    (PSGIServerContext $c, Str $data)

_write accesses the proper wheel for this context and puts the supplied data into the output buffer
