iterator nlohmann::basic_json::insert ( const_iterator  pos,
const basic_json val 
)
inline

Inserts element val before iterator pos.

Parameters
[in]positerator before which the content will be inserted; may be the end() iterator
[in]valelement to insert
Returns
iterator pointing to the inserted val.
Exceptions
type_error.309if called on JSON values other than arrays; example: "cannot use insert() with string"
invalid_iterator.202if pos is not an iterator of *this; example: "iterator does not fit current value"
Complexity^^ Constant plus linear in the distance between pos and end of
the container.
Example^^ The example shows how insert() is used. ^^ insert.cpp
Output (play with this example online):^^
10
[1,2,10,3,4]
^^ The example code above can be translated with
g++ -std=c++11 -Isingle_include doc/examples/insert.cpp -o insert
