def [](key)
  return nil unless has_property?(key.to_s)

  to_ruby_property(key.to_s)
end

#[]=(k, v) ⇒ Object

Sets the property of this node. Property keys are always strings. Valid property value types are the primitives: (String, Fixnum, Float, FalseClass, TrueClass) or an array of those primitives.

Gotchas

  • Values in the array must be of the same type.

  • You can not delete or add one item in the array (e.g. person.phones.delete(‘123’)) but instead you must create a new array instead.

Parameters:

  • k (String, Symbol) —

    of the property to set

  • v (String, Fixnum, Float, true, false, Array) —

    to set
