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

(Constant) member iterator for a JSON object value

模板参数
ConstIs this a constant iterator?
EncodingEncoding of the value. (Even non-string values need to have the same encoding in a document)
AllocatorAllocator 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].

注解
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.

构造及析构函数说明

◆ GenericMemberIterator() [1/2]

template<bool Const, typename Encoding, typename Allocator>
rapidjson::GenericMemberIterator< Const, Encoding, Allocator >::GenericMemberIterator ( )
inline

Default constructor (singular value)

Creates an iterator pointing to no element.

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

◆ GenericMemberIterator() [2/2]

template<bool Const, typename Encoding, typename Allocator>
rapidjson::GenericMemberIterator< Const, Encoding, Allocator >::GenericMemberIterator ( const NonConstIterator &  it)
inline

Iterator conversions to more const

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