NAME
Catalyst::Engine - The Catalyst Engine
SYNOPSIS
See Catalyst.
DESCRIPTION
METHODS
$self->finalize_body($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)
Abstract method, allows engines to write headers to response
$self->finalize_read($c)
$self->finalize_uploads($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.
$self->prepare_connection($c)
Abstract method implemented in engines.
$self->prepare_cookies($c)
Parse cookies from header. Sets a CGI::Simple::Cookie object.
$self->prepare_headers($c)
$self->prepare_parameters($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 from the engine.
$self->prepare_request(@arguments)
Populate the context object from the request object.
$self->prepare_uploads($c)
$self->prepare_write($c)
Abstract method. Implemented by the engines.
$self->read($c, [$maxlength])
$self->read_chunk($c, $buffer, $length)
Each engine implements read_chunk as its preferred way of reading a chunk of data.
$self->read_length
The length of input data to be read. This is obtained from the Content-Length header.
$self->read_position
The amount of input data that has already been read.
$self->run($c)
Start the engine. Implemented by the various engine classes.
$self->write($c, $buffer)
Writes the buffer to the client.
$self->unescape_uri($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 enviroment variables including many special variables inserted by WWW server - like SERVER_*, REMOTE_*, HTTP_* ...
Before accesing enviroment 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 enviroment variable from your Catalyst application you should use $c->engine->env->{VARNAME} instead of $ENV{VARNAME}, as in some enviroments the %ENV hash does not contain what you would expect.
