From documentation:

.get_json ( node , li_attr , a_attr )

This function returns an array of tree nodes converted back to JSON.

More info about same function from this doc:

This function traverses the whole tree and exports it as JSON. Refer do the data sources section to see the format of the output.

If you specify a node as the first argument, only that node and its children are included in the export, otherwise the whole tree is exported.

Just search and you shall find! :)
