Rapidjson why i can query array with index only with ConstValueIterator in c++

[meiry]

Hello all , just started to use the this great lib and i have question :
i have this simple part of json :

"foo" : [{
				"Name" : "t1",
				"things" : []
			}, {
				"name" : "t2",
				"things" : []
			}
		],

Array that contains objects , this is part of much larger json
rapidjson::Value& foo = jsonValue["foo"];
constructFoo(&foo);

This is the function that iterate the array of objects

constructFoo(rapidjson::Value* jsonValue)
{
for (rapidjson::SizeType i = 0; i < jsonValue->Size(); i++) 
	{
		rapidjson::Value& fooObj = jsonValue[i];
    }

}

The jsonValue->Size() value is 2
but the fooObj keep return the all Array foo
and not the object per index

This on the other hard works fine ,

for (rapidjson::Value::ConstValueIterator itr = jsonValue->Begin(); itr != jsonValue->End(); ++itr)
	{
		rapidjson::Type tt = itr->GetType();  // Is type Object 
		 
            
	}

What is the difference ? why simple index based loop don't work ?

Since jsonValue is a pointer in:

constructFoo(rapidjson::Value* jsonValue)

So you need to dereference it to use operator[], e.g.

rapidjson::Value& fooObj = (*jsonValue)[i];
