Public Instance Methods

[](name) click to toggle source

To find the reference, first check for standard method access by using respond_to?.

If not found, check to see if the value is a hash and if the the name is a key on the hash.

Not a hash, or not a key on the hash, then check to see if there is an instance variable with the name.

If the instance variable doesn't exist and there is a parent object, go through the same steps on the parent object. This is useful when you are iterating over objects.

# File lib/slim/wrapper.rb, line 23
def [](name)
  return wrap(value.send(name)) if value.respond_to?(name)
  if value.respond_to?(:has_key?)
    return wrap(value[name.to_sym]) if value.has_key?(name.to_sym)
    return wrap(value[name.to_s]) if value.has_key?(name.to_s)
  end
  return wrap(value.instance_variable_get("@#{name}")) if value.instance_variable_defined?("@#{name}")
  parent[name] if parent
end
