Specifies that attribute should be resolved. If :class is specified, resolve attribute only for objects of type class. The block must return the value to which the attribute should be assigned. The object for which the attribute is to be resolved will be accessible in the current context within the block.

# File lib/rgen/instantiator/abstract_instantiator.rb, line 23
def self.resolve(attribute, desc=nil, &block)
        from = (desc.is_a?(Hash) && desc[:class])
        self.resolver_descs ||= []
        self.resolver_descs << ResolverDescription.new(from, attribute, block)
end

# File lib/rgen/instantiator/abstract_instantiator.rb, line 32
def self.resolve_by_id(attribute, desc)
        id_attr = (desc.is_a?(Hash) && desc[:id])
        src_attr = (desc.is_a?(Hash) && desc[:src])
        raise StandardError.new("No id attribute given.") unless id_attr
        resolve(attribute) do
                @env.find(id_attr => @current_object.send(src_attr)).first
