The header file nxLibFunctions.h provides a basic set of functions to read and write nodes of the parameter tree.

NxLib interface functions always take a path to an item in the tree to operate on. Arrays and Objects can be read/written element wise, or by using the functions with the suffix "Json". They return or write an entire subtree via its JSON representation.

Note: Some of the library's own nodes are read only and cannot be modified or deleted. You can see the corresponding permissions in NxTreeEdit.
