# <small>nlohmann::basic_json::</small>object_comparator_t
|
|
|
|
```cpp
|
|
using object_comparator_t = typename object_t::key_compare;
|
|
// or
|
|
using object_comparator_t = default_object_comparator_t;
|
|
```
|
|
|
|
The comparator used by [`object_t`](object_t.md). Defined as `#!cpp typename object_t::key_compare` if available,
|
|
and [`default_object_comparator_t`](default_object_comparator_t.md) otherwise.
