Instance Method Details

#resolve(xml_element, mapping, needs, options, is_root: false, parent_format: nil, parent_namespace_class: nil, parent_namespace_prefix: nil, parent_hoisted: {}) ⇒ String?

Resolve the prefix decision for an element

Parameters:

  • xml_element (XmlDataModel::XmlElement) —

    The element

  • mapping (Xml::Mapping) —

    The mapping

  • needs (NamespaceNeeds) —

    Namespace needs

  • options (Hash) —

    Serialization options

  • is_root (Boolean) (defaults to: false) —

    Whether this is the root element

  • parent_format (Symbol, nil) (defaults to: nil) —

    Parent’s format (:prefix or :default)

  • parent_namespace_class (Class, nil) (defaults to: nil) —

    Parent’s namespace class

  • parent_namespace_prefix (String, nil) (defaults to: nil) —

    Parent’s actual namespace prefix (nil if default format)

  • parent_hoisted (Hash) (defaults to: {}) —

    Namespaces hoisted on parent => uri

Returns:

  • (String, nil) —

    The prefix to use, or nil for default format
