Package net.minidev.json.actions.navigate
Navigate user-specified paths in a tree made up of
Maps and List and process them
TreeNavigator only navigates through branches corresponding
to user-specified paths. For each path, the navigation starts at the root and moves down the branch.
The TreeNavigator accepts a
NavigateAction and provides callback hooks at each significant
step which the NavigateAction may use to process
the nodes.
A path to navigate must be specified in the n-gram format - a list of keys from the root down separated by dots:
K0[[[[.K1].K2].K3]...]
A key to the right of a dot is a direct child of a key to the left of a dot. Keys with a dot in their name are
not supported.
Sample usage:
NavigateAction navAction = new NavigateAction(){...};
JSONNavigator jsonNav = new JSONNavigator(navAction, "foo.bar.path");
jsonNav.nav(new JSONObject(...));
Object result = navAction.result();
