详细描述

template<typename Encoding, typename Allocator, typename StackAllocator>
class rapidjson::GenericDocument< Encoding, Allocator, StackAllocator >

A document for parsing JSON text as DOM.

注解: implements Handler concept

模板参数

Encoding	Encoding for both parsing and string storage.
Allocator	Allocator for allocating memory for the DOM
StackAllocator	Allocator for allocating memory for stack during parsing.

警告: Although GenericDocument inherits from GenericValue, the API does not provide any virtual functions, especially no virtual destructor. To avoid memory leaks, do not delete a GenericDocument object via a pointer to a GenericValue.
