◆ insert() [4/5]
template<template< typename U, typename V, typename... Args > class ObjectType = std::map, template< typename U, typename... Args > class ArrayType = std::vector, class StringType = std::string, class BooleanType = bool, class NumberIntegerType = std::int64_t, class NumberUnsignedType = std::uint64_t, class NumberFloatType = double, template< typename U > class AllocatorType = std::allocator, template< typename T, typename SFINAE=void > class JSONSerializer = adl_serializer>
Inserts elements from range [first, last) before iterator pos.
- Parameters
-
[in] | pos | iterator before which the content will be inserted; may be the end() iterator |
[in] | first | begin of the range of elements to insert |
[in] | last | end of the range of elements to insert |
- Exceptions
-
std::domain_error | if called on JSON values other than arrays; example: "cannot use insert() with string" |
std::domain_error | if pos is not an iterator of *this; example: "iterator does not fit current value" |
std::domain_error | if first and last do not belong to the same JSON value; example: "iterators do not fit" |
std::domain_error | if first or last are iterators into container for which insert is called; example: "passed iterators may not
belong to container" |
- Returns
- iterator pointing to the first element inserted, or pos if
first==last
- Complexity
- Linear in
std::distance(first, last) plus linear in the distance between pos and end of the container.
- Example
- The example shows how
insert() is used. 11 json v2 = { "one", "two", "three", "four"}; 14 auto new_pos = v.insert(v.end(), v2.begin(), v2.end()); 17 std::cout << *new_pos << '\n'; 18 std::cout << v << '\n'; basic_json<> json default JSON class
Output (play with this example online): "one"
[1,2,3,4,"one","two","three","four"]
The example code above can be translated withg++ -std=c++11 -Isrc doc/examples/insert__range.cpp -o insert__range
- Since
- version 1.0.0
