Function GetBoolean

parser.go:1995–2010

GetBoolean returns the value retrieved by `Get`, cast to a bool if possible. The offset is the same as in `Get`. If key data type do not match, it will return error. SYS-REQ-005, SYS-REQ-079

(data []byte, keys ...string)

// If key data type do not match, it will return error.
// SYS-REQ-005, SYS-REQ-079

	v, t, _, e := Get(data, keys...)

	if e != nil {
		return false, e
	}

	if t != Boolean {
		if t == Null {
			return false, NullValueError

		return false, fmt.Errorf("Value is not a boolean: %s", string(v))
	}

	return ParseBoolean(v)
}
