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

GenericValue ( )

Default constructor creates a null value.

Definition at line 562 of file document.h.

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

Move constructor in C++11.

Definition at line 566 of file document.h.

GenericValue ( Type type ) [explicit]

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 592 of file document.h.

GenericValue	(	const GenericValue< Encoding, SourceAllocator > &	rhs,
		Allocator &	allocator
	)

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().

See also:: CopyFrom()

Definition at line 2408 of file document.h.

GenericValue	(	T	b,
		RAPIDJSON_ENABLEIF((internal::IsSame< bool, T >))
	)		`[explicit]`

Constructor for boolean value.

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.

Definition at line 623 of file document.h.

GenericValue ( int i ) [explicit]

Constructor for int value.

Definition at line 634 of file document.h.

GenericValue ( unsigned u ) [explicit]

Constructor for unsigned value.

Definition at line 640 of file document.h.

GenericValue ( int64_t i64 ) [explicit]

Constructor for int64_t value.

Definition at line 646 of file document.h.

GenericValue ( uint64_t u64 ) [explicit]

Constructor for uint64_t value.

Definition at line 661 of file document.h.

GenericValue ( double d ) [explicit]

Constructor for double value.

Definition at line 673 of file document.h.

GenericValue	(	const Ch *	s,
		SizeType	length
	)

Constructor for constant string (i.e. do not make a copy of string)

Definition at line 676 of file document.h.

GenericValue ( StringRefType s ) [explicit]

Constructor for constant string (i.e. do not make a copy of string)

Definition at line 679 of file document.h.

GenericValue	(	const Ch *	s,
		SizeType	length,
		Allocator &	allocator
	)

Constructor for copy-string (i.e. do make a copy of string)

Definition at line 682 of file document.h.

GenericValue	(	const Ch *	s,
		Allocator &	allocator
	)

Constructor for copy-string (i.e. do make a copy of string)

Definition at line 685 of file document.h.

GenericValue	(	const std::basic_string< Ch > &	s,
		Allocator &	allocator
	)

Constructor for copy-string from a string object (i.e. do make a copy of string)

Note:: Requires the definition of the preprocessor symbol RAPIDJSON_HAS_STDSTRING.

Definition at line 691 of file document.h.

GenericValue ( Array a )

Constructor for Array.

Parameters:

a	An array obtained by `GetArray()`.

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

Definition at line 700 of file document.h.

GenericValue ( Object o )

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.

Need to destruct elements of array, members of object, or copy-string.

Definition at line 719 of file document.h.

Member Function Documentation

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

Assignment with move semantics.

Parameters:

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

Definition at line 755 of file document.h.

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

Move assignment in C++11.

Definition at line 764 of file document.h.

GenericValue& operator= ( StringRefType str )

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.

See also:: GenericStringRef, operator=(T)

Definition at line 774 of file document.h.

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

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

Assignment without calling destructor.

Definition at line 1984 of file document.h.

void SetObjectRaw	(	Member *	members,
		SizeType	count,
		Allocator &	allocator
	)

Initialize this value as object with initial data, without calling destructor.

Definition at line 1947 of file document.h.

void SetStringRaw ( StringRefType s )

Initialize this value as constant string, without calling destructor.

Definition at line 1960 of file document.h.

void SetStringRaw	(	StringRefType	s,
		Allocator &	allocator
	)

Initialize this value as copy string with initial data, without calling destructor.

Definition at line 1967 of file document.h.
