Contract

  1. parseDocument parses YAML alias nodes into Alias AST instances
  2. Alias.resolve resolves an alias node to its referenced target AST node
  3. Document.createAlias generates an anchor on the target node and returns an Alias AST instance
  4. new Alias constructs an Alias AST instance referencing an anchor name
  5. Document.toJS resolves aliases and returns fully populated JavaScript objects
  6. Document.toString serializes Alias nodes with valid YAML anchor and alias syntax
