サマリー
This object provides access to a network dataset's properties, attributes, attribute values, and elements.
説明
A NetworkQuery object is provided as a parameter to the attach method, and other methods can use self.networkQuery to this object. A NetworkQuery object can be used to get various properties of a network dataset or query a network dataset for attributes, elements, and so on.
