Package net.minidev.json.actions.traverse

Traverse all the nodes in a JSONObject and process them

The traversal starts at the root and moves breadth-first down the branches. The TreeTraverser accepts a JSONTraverseAction and provides callback hooks at each significant step which the JSONTraverseAction may use to process the nodes.

The TreeTraverser assumes that paths in the tree which the JSONObject represents are 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:

 TraverseAction tAction = new TraverseAction(){...};
 JSONTraverser jsonTrv = new JSONTraverser(tAction);
 jsonTrv.traverse(new JSONObject(...));
 Object result = tAction.result();
