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>
Removes element from a JSON array at the index idx.
- Parameters
-
[in] | idx | index of the element to remove |
- Exceptions
-
std::domain_error | when called on a type other than JSON array; example: "cannot use erase() with null" |
std::out_of_range | when idx >= size() ; example: "array index 17
is out of range" |
- Complexity\n Linear in distance between idx and the end of the container.
- Example\n The example shows the effect of
erase() . \n @includelineno erase__size_type.cpp \n Output (play with this example @htmlinclude erase__size_type.link):\n @verbinclude erase__size_type.output \n The example code above can be translated with @verbatim g++ -std=c++11 -Isrc doc/examples/erase__size_type.cpp -o erase__size_type @endverbatim
