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.

Constructor & Destructor Documentation

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

GenericValue< Encoding, Allocator >::GenericValue ( )

inline

Default constructor creates a null value.

Definition at line 581 of file document.h.

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

GenericValue< Encoding, Allocator >::GenericValue ( const GenericValue< Encoding, Allocator > & rhs )

private

Copy constructor is not permitted.

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

GenericValue< Encoding, Allocator >::GenericValue ( Type type )

inlineexplicit

Constructor with JSON value type.

This creates a Value of specified type with default content.

Parameters

type	Type of the value.

Note: Default content for number is zero.

Definition at line 611 of file document.h.

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

template<typename SourceAllocator >

GenericValue< Encoding, Allocator >::GenericValue	(	const GenericValue< Encoding, SourceAllocator > &	rhs,
		Allocator &	allocator,
		bool	copyConstStrings = `false`
	)

inline

Explicit copy constructor (with allocator)

Creates a copy of a Value by using the given Allocator

Template Parameters

SourceAllocator allocator of rhs

Parameters

rhs	Value to copy from (read-only)
allocator	Allocator for allocating copied elements and buffers. Commonly use GenericDocument::GetAllocator().
copyConstStrings	Force copying of constant strings (e.g. referencing an in-situ buffer)

See also: CopyFrom()

Parameters

b	Boolean value

Note: This constructor is limited to real boolean values and rejects implicitly converted types like arbitrary pointers. Use an explicit cast to bool, if you want to construct a boolean JSON value in such cases.

GenericValue< Encoding, Allocator >::GenericValue ( Array a )

inline

Constructor for Array.

Parameters

a	An array obtained by `GetArray()`.

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

GenericValue< Encoding, Allocator >::GenericValue ( Object o )

inline

Constructor for Object.

Parameters

o	An object obtained by `GetObject()`.

Note: Object is always pass-by-value.; the source object is moved into this value and the sourec object becomes empty.

template<typename T >

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

	)

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
