HTML::Mason::Compiler::ToObject.3pm

NAME

HTML::Mason::Compiler::ToObject - A Compiler subclass that generates Mason object code

SYNOPSIS

   my $compiler = HTML::Mason::Compiler::ToObject->new;
 
   my $object_code =
       $compiler->compile( comp_source => $source,
                           name        => $comp_name,
                           comp_path   => $comp_path,
                         );
 
 

DESCRIPTION

This Compiler subclass generates Mason object code (Perl code). It is the default Compiler class used by Mason.

PARAMETERS TO THE new() CONSTRUCTOR

All of these parameters are optional.

comp_class

The class into which component objects are blessed. This defaults to HTML::Mason::Component.

subcomp_class

The class into which subcomponent objects are blessed. This defaults to HTML::Mason::Component::Subcomponent.

in_package

This is the package in which a component's code is executed. For historical reasons, this defaults to "HTML::Mason::Commands".

preamble

Text given for this parameter is placed at the beginning of each component, but after the execution of any "<%once>" block. See also postamble. The request will be available as $m in preamble code.

postamble

Text given for this parameter is placed at the end of each component. See also preamble. The request will be available as $m in postamble code.

use_strict

True or false, default is true. Indicates whether or not a given component should "use strict".

named_component_subs

When compiling a component, use uniquely named subroutines for the a component's body, subcomponents, and methods. Doing this allows you to effectively profile Mason components. Without this, all components simply show up as __ANON__ or something similar in the profiler.

define_args_hash

One of ``always'', ``auto'', or ``never''. This determines whether or not an %ARGS hash is created in components. If it is set to ``always'', one is always defined. If set to ``never'', it is never defined.

The default, ``auto'', will cause the hash to be defined only if some part of the component contains the string ``ARGS''. This is somewhat crude, and may result in some false positives, but this is preferable to false negatives.

Not defining the args hash means that we can avoid copying component arguments, which can save memory and slightly improve execution speed.

ACCESSOR METHODS

All of the above properties have read-only accessor methods of the same name. You cannot change any property of a compiler after it has been created (but you can create multiple compilers with different properties).

METHODS

This class is primarily meant to be used by the Interpreter object, and as such has a very limited public API.

compile (comp_source => $source, name => $name, comp_class = $comp_class)

This method will take component source and return the compiled object code for that source. The "comp_source" and "name" parameters are optional. The "comp_class" can be used to change the component class for this one comonent.
