[RFC 8259](https://tools.ietf.org/html/rfc8259) implicitly describes a boolean as a type which differentiates the two literals

|
|
|
`#!json true` and `#!json false`.
|
|
|
|
|
|
|
|
|
|
To store objects in C++, a type is defined by the template parameter `BooleanType` which chooses the type to use.

## Notes
|
|
|
|
|
|
|
|
|
|
#### Default type
|
|
|
|
|
|
|
|
|
|
With the default values for `BooleanType` (`#!cpp bool`), the default value for `boolean_t` is `#!cpp bool`.
|
|
|
|
|
|
|
|
|
|
#### Storage
|
|
|
|
|
|
|
|
|
|
Boolean values are stored directly inside a `basic_json` type.
