IOC::Visitor::ServiceLocator(3) User Contributed Perl Documentation IOC::Visitor::ServiceLocator(3)

IOC::Visitor::ServiceLocator - Service locator Visitor for the IOC::Container hierarchies

  use IOC::Visitor::ServiceLocator;

  # given a $container, ...

  # find services within $container
  my $visitor = IOC::Visitor::ServiceLocator->new('connection');

  # find services relative to $container
  my $visitor = IOC::Visitor::ServiceLocator->new('../connection');
  
  # find services from $container's root  
  my $visitor = IOC::Visitor::ServiceLocator->new('/database/connection');
  
  $container->accept($visitor);

This is a IOC::Visitor object, used by the IOC::Container's "find" method to locate a service using a path syntax.

new ($path)
Creates a new instance which will find Services at a given $path. If no $path is given, than an IOC::InsufficientArguments exception is thrown.
visit ($container)
Given a $container, the invocant will attempt to locate the service at the $path (given to the constuctor) from within the $container.

Work on the documentation

None that I am aware of. Of course, if you find a bug, let me know, and I will be sure to fix it.

I use Devel::Cover to test the code coverage of my tests, see the CODE COVERAGE section of IOC for more information.
