Catalyst::Engine(3) User Contributed Perl Documentation Catalyst::Engine(3)NAMECatalyst::Engine - The Catalyst Engine
SYNOPSIS
See Catalyst.
DESCRIPTIONMETHODS
$self->finalize_body($c)
Finalize body. Prints the response output.
$self->finalize_cookies($c)
Create CGI::Simple::Cookie objects from $c->res->cookies, and set them
as response headers.
$self->finalize_error($c)
Output an appropriate error message. Called if there's an error in $c
after the dispatch has finished. Will output debug messages if Catalyst
is in debug mode, or a `please come back later` message otherwise.
$self->finalize_headers($c)
Allows engines to write headers to response
$self->finalize_uploads($c)
Clean up after uploads, deleting temp files.
$self->prepare_body($c)
sets up the Catalyst::Request object body using HTTP::Body
$self->prepare_body_chunk($c)
Add a chunk to the request body.
$self->prepare_body_parameters($c)
Sets up parameters from body.
$self->prepare_parameters($c)
sets up parameters from query and post parameters.
$self->prepare_path($c)
abstract method, implemented by engines.
$self->prepare_request($c)
$self->prepare_query_parameters($c)
process the query string and extract query parameters.
$self->prepare_read($c)
Prepare to read by initializing the Content-Length from headers.
$self->prepare_request(@arguments)
Populate the context object from the request object.
$self->prepare_uploads($c)
$self->write($c, $buffer)
Writes the buffer to the client.
$self->read($c, [$maxlength])
Reads from the input stream by calling "$self->read_chunk".
Maintains the read_length and read_position counters as data is read.
$self->read_chunk($c, \$buffer, $length)
Each engine implements read_chunk as its preferred way of reading a
chunk of data. Returns the number of bytes read. A return of 0
indicates that there is no more data to be read.
$self->run($app, $server)
Start the engine. Builds a PSGI application and calls the run method on
the server passed in, which then causes the engine to loop, handling
requests..
build_psgi_app ($app, @args)
Builds and returns a PSGI application closure. (Raw, not wrapped in
middleware)
$self->unescape_uri($uri)
Unescapes a given URI using the most efficient method available.
Engines such as Apache may implement this using Apache's C-based
modules, for example.
$self->finalize_output
<obsolete>, see finalize_body
$self->env
Hash containing environment variables including many special variables
inserted by WWW server - like SERVER_*, REMOTE_*, HTTP_* ...
Before accessing environment variables consider whether the same
information is not directly available via Catalyst objects $c->request,
$c->engine ...
BEWARE: If you really need to access some environment variable from
your Catalyst application you should use $c->engine->env->{VARNAME}
instead of $ENV{VARNAME}, as in some environments the %ENV hash does
not contain what you would expect.
