Detailed Description

template<typename Encoding, typename Allocator = MemoryPoolAllocator<>>
class GenericValue< Encoding, Allocator >

Represents a JSON value. Use Value for UTF8 encoding and default allocator.

A JSON value can be one of 7 types. This class is a variant type supporting these types.

Use the Value if UTF8 and default allocator

Template Parameters

Encoding	Encoding of the value. (Even non-string values need to have the same encoding in a document)
Allocator	Allocator type for allocating memory of object, array and string.

operator=() [1/2]

GenericValue& operator= ( GenericValue< Encoding, Allocator > &  rhs )

inline

Assignment with move semantics.

Parameters

rhs	Source of the assignment. It will become a null value after assignment.

Definition at line 836 of file document.h.

                                                                  {

Here is the caller graph for this function:

operator=() [2/2]

GenericValue& operator= ( StringRefType  str )

inline

Assignment of constant string reference (no copy)

Parameters

str	Constant string reference to be assigned

Note

This overload is needed to avoid clashes with the generic primitive type assignment overload below.

RAPIDJSON_DISABLEIF_RETURN()

RAPIDJSON_DISABLEIF_RETURN	(	(internal::IsPointer< T >)	,
		(GenericValue< Encoding, Allocator > &)
	)

Assignment with primitive types.

Template Parameters

T	Either Type, int, unsigned, int64_t, uint64_t

Parameters

value

The value to be assigned.

Note

The source type T explicitly disallows all pointer types, especially (const) Ch*. This helps avoiding implicitly referencing character strings with insufficient lifetime, use SetString(const Ch*, Allocator&) (for copying) or StringRef() (to explicitly mark the pointer as constant) instead. All other pointer types would implicitly convert to bool, use SetBool() instead.Set boolean value

RawAssign()

void RawAssign ( GenericValue< Encoding, Allocator > &  rhs )

inline

Assignment without calling destructor.
