ola::web::PointerTracker Class Reference

Detailed Description

Maintains a Json Pointer (RFC 6901) given a set of Json parse events.

Given the JSON:

{
  "foo": {
    "bar": 1,
    "baz": true
  },
  "bat": [0, 1, 2]
}

It has the pointers:

• ""
• "/foo"
• "/foo/bar"
• "/foo/baz"
• "/bat"
• "/bat/0"
• "/bat/1"
• "/bat/2"

When parsing this example, the order of method invocation should be:

JsonPointer pointer;
PointerTracker tracker(&pointer);

tracker.OpenObject()
tracker.SetProperty("foo");
tracker.OpenObject();
tracker.SetProperty("bar");
tracker.SetProperty("baz");
tracker.CloseObject();
tracker.SetProperty("bat");
tracker.OpenArray();
tracker.IncrementIndex();
tracker.IncrementIndex();
tracker.IncrementIndex();
tracker.CloseArray();
tracker.CloseObject();

Public Member Functions
	PointerTracker (JsonPointer *pointer)
void	OpenObject ()
	Open a new Object Element.
void	SetProperty (const std::string &property)
	Set the property name within an Object element. Note if we're not currently in an object element this has no effect.
void	CloseObject ()
	Close an Object element. Note if we're not currently in an object element this has no effect.
void	OpenArray ()
	Open a new Array Element Note that until IncrementIndex() is called, the array index will be -1. This is so you can call IncrementIndex() on each element.
void	CloseArray ()
	Close an Array Element If we're not currently in an array this doesn't do anything.
void	IncrementIndex ()
	Increment an array index. If we're not current in an array this doesn't do anything.
