Description
-----------
BrainTwister record is a linear, direct-accessible, heterogeneous
data structure, which is defined by
```
BRAINTWISTER_RECORD( record_name, \
(( entry_type, entry_name, entry_default_value )) \
... \
)
```
For instance, a database connection can be defined as
```
BRAINTWISTER_RECORD( Database, \
(( uint16_t, port, 3306 )) \
(( std::string, database, "" )) \
(( std::string, table, "" )) \
)
```
The entries are statically typed and are directly accessible using the dot operator
```
Database db;
std::cout << db.database << std::endl;
```
A record can be initialized with a build pattern
```
Database db.set_port(9876);
```
or with JSON/XML
```
{
"port": 9876,
"database": "staff",
"table": "employees"
}
```
Nested records and std::vector are supported.
Polymorphic record
------------------
For a polymorphic record a macro for the base class and for
the derived classes have to be defined by
```
BRAINTWISTER_RECORD_BASE( base_recor_name, \
(( base_entry_type, base_entry_name, base_entry_default_value )) \
..., \
virtual function \
)
BRAINTWISTER_RECORD_DERIVED( derived_record_name, \
(( derived_entry_type, derived_entry_name, derived_entry_default_value )) \
..., \
virtual function \
)
```
