◆ insert() [3/6]
template<template< typename, typename, typename... > class ObjectType = std::map, template< typename, typename... > 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 > class AllocatorType = std::allocator, template< typename, typename=void > class JSONSerializer = adl_serializer>
Inserts cnt copies of val before iterator pos.
- Parameters
-
[in] | pos | iterator before which the content will be inserted; may be the end() iterator |
[in] | cnt | number of copies of val to insert |
[in] | val | element to insert |
- Returns
- iterator pointing to the first element inserted, or pos if
cnt==0
- Exceptions
-
type_error.309 | if called on JSON values other than arrays; example: "cannot use insert() with string" |
invalid_iterator.202 | if pos is not an iterator of *this; example: "iterator does not fit current value" |
- Complexity
- Linear in cnt plus linear in the distance between pos and end of the container.
- Example
- The example shows how
insert() is used. 12 auto new_pos = v.insert(v.begin() + 2, 7, 7); 15 std::cout << *new_pos << '\n'; 16 std::cout << v << '\n'; basic_json<> json default JSON class
Output (play with this example online): 7
[1,2,7,7,7,7,7,7,7,3,4]
The example code above can be translated withg++ -std=c++11 -Isrc doc/examples/insert__count.cpp -o insert__count
- Since
- version 1.0.0
