![]() ![]() MemberIterator EraseMember(MemberIterator): similar to the above but it preserves order of members (linear time complexity).MemberIterator RemoveMember(MemberIterator): Remove a member by iterator ( constant time complexity).bool RemoveMember(const Value& name): same as above but name is a Value.bool RemoveMember(const Ch* name): Remove a member by search its name (linear time complexity).If you need to handle this, you can use GetStringLength() to obtain the correct string length.įor example, after parsing the following JSON to Document d:Ĭontact.AddMember(key, val, document.GetAllocator()) įor removing members, there are several choices: To conform with RFC 4627, RapidJSON supports string containing U+0000 character. The problem is that, C/C++ often uses null-terminated string, which treats \0 as the terminator symbol. Here explains why:Īccording to RFC 4627, JSON strings can contain Unicode character U+0000, which must be escaped as "\u0000". In addition to GetString(), the Value class also contains GetStringLength(). Note that, int and unsigned can be safely converted to double, but int64_t and uint64_t may lose precision (since mantissa of double is only 52-bits). When obtaining the numeric values, GetDouble() will convert internal integer representation to a double. ![]() But a value y containing -3000000000 will only make x.IsInt64() = true. For example, A value x containing 123 will make x.IsInt() = x.IsUint() = x.IsInt64() = x.IsUint64() = true. Note that, an integer value may be obtained in various ways without conversion. When querying a number, you can check whether the number can be obtained as the target type: Checking When a Number is parsed, it is stored in the DOM as one of the following types: Type RFC 4627 says the range of Number is specified by the parser implementation.Īs C++ provides several integer and floating point number types, the DOM tries to handle these with the widest possible range and good performance. Number can be an integer or a real number. JSON provides a single numerical type called Number. ![]()
