NAME ^

Bread::Board::Traversable

VERSION ^

version 0.33

SYNOPSIS ^

  my $service = $container->fetch('/some/service/path');

  my $root = $service->get_root_container;

DESCRIPTION ^

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.

ATTRIBUTES ^

parent

Weak ref to another Bread::Board::Traversable object, read/write accessor (although you should probably not change this value directly in normal code).

METHODS ^

has_parent

Predicate for the "parent" attribute, true if a parent has been set.

detach_from_parent

Clearer for the "parent" attribute, you should probably not call this method in normal code.

get_root_container

Returns the farthest ancestor of the invocant, i.e. the top-most container this object is a part of.

fetch

  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.
