# nlohmann::json_sax
|
|
|
|
```
|
|
template<typename BasicJsonType>
|
|
struct json_sax;
|
|
```
|
|
|
|
This class describes the SAX interface used by [sax_parse](https://json.nlohmann.me/api/basic_json/sax_parse/index.md). Each function is called in different situations while the input is parsed. The boolean return value informs the parser whether to continue processing the input.
|
|
|
|
## Template parameters
|
|
|
|
`BasicJsonType` : a specialization of [`basic_json`](https://json.nlohmann.me/api/basic_json/index.md)
|
|
|
|
## Member types
|
|
|
|
- [**number_integer_t**](https://json.nlohmann.me/api/basic_json/number_integer_t/index.md) - `BasicJsonType`'s type for numbers (integer)
|
|
- [**number_unsigned_t**](https://json.nlohmann.me/api/basic_json/number_unsigned_t/index.md) - `BasicJsonType`'s type for numbers (unsigned)
|
|
- [**number_float_t**](https://json.nlohmann.me/api/basic_json/number_float_t/index.md) - `BasicJsonType`'s type for numbers (floating-point)
|
|
- [**string_t**](https://json.nlohmann.me/api/basic_json/string_t/index.md) - `BasicJsonType`'s type for strings
|
|
- [**binary_t**](https://json.nlohmann.me/api/basic_json/binary_t/index.md) - `BasicJsonType`'s type for binary arrays
