Detailed Description

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

A document for parsing JSON text as DOM.

Note

implements Handler concept

Template Parameters

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.

Warning

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.
