Creation methods:

• public HashPairedMap ()

Methods:

• public DomElement? @get (string primary_key, string secondary_key)
  Returns an DomElement in the collection using given string keys.
• public override void clear ()
• public List<string> get_primary_keys ()
  Returns list of primary keys used in collection.
• public List<string> get_secondary_keys (string pkey)
  Returns list of secondary keys used in collection with @pkey as primary key.
• public bool has_primary_key (string key)
  Returns true if @key is used in collection as primary key.
• public bool has_secondary_key (string pkey, string key)
  Returns true if @key is used in collection as secondary key with @pkey as primary.
• public void initialize_element_with_keys (Element element, Type items_type, string attribute_primary_key, string attribute_secondary_key) throws Error
  Convenient function to initialize a GXml.HashMap collection, using given element, items' type and name.
• public void initialize_with_keys (Type items_type, string attribute_primary_key, string attribute_secondary_key) throws Error
  Convenient function to initialize a GXml.HashMap collection, using given element, items' type and name.
• public DomElement? item (string primary_key, string secondary_key)
• public Set<string> secondary_keys_set (string pkey)
• public override bool validate_append (int index, DomElement element) throws Error
  Validates if given element has a attribute_primary_key and attribute_secondary_key set, if so adds a new keys pointing to given index and returns true.

Fields:

• protected string _attribute_primary_key
  Element's attribute name used to refer of container's element as primary key. You should define it at construction time our set it as a construction property.
• protected string _attribute_secondary_key
  Element's attribute name used to refer of container's element as secondary key. You should define it at construction time our set it as a construction property.
• protected HashMap<string,HashMap<string,int>> _hashtable
  A hashtable with all keys as string to node's index referred. Don't modify it manually.
