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]

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

GenericValue & GenericValue< Encoding, Allocator >::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 833 of file document.h.

                                                                {

◆ operator=() [2/2]

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

GenericValue & GenericValue< Encoding, Allocator >::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.

template<typename T>

GenericValue< Encoding, Allocator >::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()

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

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

Assignment without calling destructor.
