Constructs a JSON array value by creating cnt copies of a passed value. In case cnt is 0 , an empty array is created. As postcondition, std::distance(begin(),end()) == cnt holds.
- Parameters
-
[in] | cnt | the number of JSON copies of val to create |
[in] | val | the JSON value to copy |
- Complexity\n Linear in cnt.
- Example\n The following code shows examples for the @ref
- basic_json(size_type, const basic_json&) constructor.
static basic_json array(std::initializer_list< basic_json > init=std::initializer_list< basic_json >()) explicitly create an array from an initializer list
@ value the parser finished reading a JSON value
a class to store JSON values
basic_json<> json default JSON class
Output (play with this example online):
[]
["Hello"]
["Hello","Hello","Hello","Hello","Hello"]
The example code above can be translated with g++ -std=c++11 -Isrc doc/examples/basic_json__size_type_basic_json.cpp -o basic_json__size_type_basic_json
- Since
- version 1.0.0
