Perform a copy of Document object of rapidjson

Question

I\'m making a class and I want to return my class inside a method. My class has a rapidjson::Document object.

You can see the previous problems here: L

Answer 1

Use the CopyFrom method on a new Document:

rapidjson::Document inDoc;    // source document
rapidjson::Document outDoc;   // destination document
outDoc.CopyFrom(inDoc, outDoc.GetAllocator());

I tested this approach and changes made to the output document had no effect on the input document. Make sure the CopyFrom method is given the output document's allocator.
