The BAR object, which is the interfacial object for deserialized data files opened for node editing, allows the user to get information about the current node.

The node navigation functions perform a specific action on the current node, which is the node to which the node cursor points. All of the functions require a BAR object to have a file loaded at the time of the function call. For BARfly, this means you can only call the functions when the current view displays a data file, and the current selection in the node browser (or subnode browser, if it appears in the data display window) is treated as the node cursor.

BARfly allows you to call all node information functions. The functions you can call by selecting Run.Run BAR Interfacial Function are as follows.

• Get_Node_Type
• Get_Child_Count
• Get_Size
• Get_Bit_Size
• Get_UID
• Get_Absolute_Position
• Get_Relative_Position
• Get_Hierarchy_Level
