Bread::Board::Traversable - role for traversing a container service tree
my $service = $container->fetch('/some/service/path'); my $root = $service->get_root_container;
This role provides the basic functionality to traverse a container / service tree. Instances of classes consuming this role will get a parent-child relationship between them.
Weak ref to another Bread::Board::Traversable object, read/write accessor (although you should probably not change this value directly in normal code).
Predicate for the "parent" attribute, true if a parent has been set.
Clearer for the "parent" attribute, you should probably not call this method in normal code.
Returns the farthest ancestor of the invocant, i.e. the top-most container this object is a part of.
my $service = $this->fetch('/absolute/path'); my $service = $this->fetch('relative/path'); my $service = $this->fetch('../relative/path');
Given a (relative or absolute) path to a service or container, this method walks the tree and returns the Bread::Board::Service or Bread::Board::Container instance for that path. Dies if no object can be found for the given path.
Aliases are resolved in this call, by calling "aliased_from" until we get an actual service.
