Detailed Description

template<bool Const, typename Encoding, typename Allocator>
class GenericMemberIterator< Const, Encoding, Allocator >

(Constant) member iterator for a JSON object value

Template Parameters

Const	Is this a constant iterator?
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.

This class implements a Random Access Iterator for GenericMember elements of a GenericValue, see ISO/IEC 14882:2003(E) C++ standard, 24.1 [lib.iterator.requirements].

Note

This iterator implementation is mainly intended to avoid implicit conversions from iterator values to NULL, e.g. from GenericValue::FindMember.

Define RAPIDJSON_NOMEMBERITERATORCLASS to fall back to a pointer-based implementation, if your platform doesn't provide the C++ <iterator> header.

Constructor & Destructor Documentation

template<bool Const, typename Encoding , typename Allocator >

GenericMemberIterator< Const, Encoding, Allocator >::GenericMemberIterator ( )

inline

Default constructor (singular value)

Creates an iterator pointing to no element.

Note

All operations, except for comparisons, are undefined on such values.

: ptr_() {}

template<bool Const, typename Encoding , typename Allocator >

GenericMemberIterator< Const, Encoding, Allocator >::GenericMemberIterator ( const NonConstIterator &  it )

inline

Iterator conversions to more const.

Parameters

it	(Non-const) iterator to copy from

Allows the creation of an iterator from another GenericMemberIterator that is "less const". Especially, creating a non-constant iterator from a constant iterator are disabled:

• const -> non-const (not ok)
• const -> const (ok)
• non-const -> const (ok)
• non-const -> non-const (ok)

Note

If the Const template parameter is already false, this constructor effectively defines a regular copy-constructor. Otherwise, the copy constructor is implicitly defined.

: ptr_(it.ptr_) {}

template<bool Const, typename Encoding , typename Allocator >

GenericMemberIterator< Const, Encoding, Allocator >::GenericMemberIterator ( Pointer  p )

inlineexplicitprivate

Internal constructor from plain pointer.

: ptr_(p) {}
