§ insert() [5/5]
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>
Inserts elements from initializer list ilist before iterator pos.
- Parameters
-
[in] | pos | iterator before which the content will be inserted; may be the end() iterator |
[in] | ilist | initializer list to insert the values from |
- 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" |
- Returns
- iterator pointing to the first element inserted, or pos if
ilist is empty
- Complexity
- Linear in
ilist.size() plus linear in the distance between pos and end of the container.
- Example
- The example shows how
insert() is used. 11 auto new_pos = v.insert(v.end(), {7, 8, 9}); 14 std::cout << *new_pos << '\n'; 15 std::cout << v << '\n'; basic_json<> json default JSON class
Output (play with this example online): 7
[1,2,3,4,7,8,9]
The example code above can be translated withg++ -std=c++11 -Isrc doc/examples/insert__ilist.cpp -o insert__ilist
- Since
- version 1.0.0
