| # <small>nlohmann::</small>json_sax |
| |
| ```cpp |
| template<typename BasicJsonType> |
| struct json_sax; |
| ``` |
| |
| This class describes the SAX interface used by [sax_parse](../basic_json/sax_parse.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`](../basic_json/index.md) |
| |
| ## Member types |
| |
| - [**number_integer_t**](../basic_json/number_integer_t.md) - `BasicJsonType`'s type for numbers (integer) |
| - [**number_unsigned_t**](../basic_json/number_unsigned_t.md) - `BasicJsonType`'s type for numbers (unsigned) |
| - [**number_float_t**](../basic_json/number_float_t.md) - `BasicJsonType`'s type for numbers (floating-point) |
| - [**string_t**](../basic_json/string_t.md) - `BasicJsonType`'s type for strings |
| - [**binary_t**](../basic_json/binary_t.md) - `BasicJsonType`'s type for binary arrays |
| |
| ## Member functions |
| |
| - [**binary**](binary.md) (_virtual_) - a binary value was read |
| - [**boolean**](boolean.md) (_virtual_) - a boolean value was read |
| - [**end_array**](end_array.md) (_virtual_) - the end of an array was read |
| - [**end_object**](end_object.md) (_virtual_) - the end of an object was read |
| - [**key**](key.md) (_virtual_) - an object key was read |
| - [**null**](null.md) (_virtual_) - a null value was read |
| - [**number_float**](number_float.md) (_virtual_) - a floating-point number was read |
| - [**number_integer**](number_integer.md) (_virtual_) - an integer number was read |
| - [**number_unsigned**](number_unsigned.md) (_virtual_) - an unsigned integer number was read |
| - [**parse_error**](parse_error.md) (_virtual_) - a parse error occurred |
| - [**start_array**](start_array.md) (_virtual_) - the beginning of an array was read |
| - [**start_object**](start_object.md) (_virtual_) - the beginning of an object was read |
| - [**string**](string.md) (_virtual_) - a string value was read |
| |
| ## Version history |
| |
| - Added in version 3.2.0. |
| - Support for binary values (`binary_t`, `binary`) added in version 3.8.0. |
