Load mix-ins or components to your C3-based class.


  package MyModule;

  use strict;
  use warnings;

  use base 'Class::C3::Componentised';

  sub component_base_class { "MyModule::Component" }

  package main;

  MyModule->load_components( qw/Foo Bar/ ); 
  # Will load MyModule::Component::Foo and MyModule::Component::Bar


This will inject base classes to your module using the Class::C3 method resolution order.

Please note: these are not plugins that can take precedence over methods declared in MyModule. If you want something like that, consider MooseX::Object::Pluggable.


load_components( @comps )

Loads the given components into the current module. If a module begins with a + character, it is taken to be a fully qualified class name, otherwise $class->component_base_class is prepended to it.

Calling this will call Class::C3::reinitialize.

load_own_components( @comps )

Similar to load_components, but assumes every class is "$class::$comp".


As load_components, but will silently ignore any components that cannot be found.


Given a class name, tests to see if it is already loaded or otherwise defined. If it is not yet loaded, the package is require'd, and an exception is thrown if the class is still not loaded.

 BUG: For some reason, packages with syntax errors are added to %INC on


Returns true if the specified class is installed or already loaded, false otherwise.

Note that the underlying mechanism (Class::Inspector->installed()) used by this sub will not, at the time of writing, correctly function when @INC includes coderefs. Since PAR relies upon coderefs in @INC, this function should be avoided in modules that are likely to be included within a PAR.


Does the actual magic of adjusting @ISA on the target module.


Returns a true value if the specified class is installed and loaded successfully, throws an exception if the class is found but not loaded successfully, and false if the class is not installed
