Description

`object` public construct/copy/destruct

```
object();
```
Constructs an empty object - no mixins.

explicit object(const object_type_template & type_template);

Constructs an object from a specific type template.

```
object(object && o);
```
Move constructor from an existing object.
```
~object();
```

`object` public member functions

template<typename Mixin> bool has() const;

Checks if the object has a specific mixin.

```
template<typename Mixin> Mixin * get();
```
Gets a specific mixin from the object. Returns nullptr if the mixin isn't available.
```
template<typename Mixin> const Mixin * get() const;
```
Gets a specific mixin from the object. Returns nullptr if the mixin isn't available.

template<typename Feature> bool implements(const Feature *) const;

Checks if the mixin implements a feature.

```
void clear();
```
Destroys all mixins within an object and resets its type info.
```
bool empty() const;
```
Returns true if the object is empty - has no mixins.

void get_message_names(std::vector< const char * > & out_message_names) const;

Adds the names of the messages implemented by the object to the vector.

void get_mixin_names(std::vector< const char * > & out_mixin_names) const;

Adds the names of the object's mixins to the vector.

const void * internal_get_mixin(mixin_id id) const;

bool internal_has_mixin(mixin_id id) const;

void change_type(const internal::object_type_info * new_type, 
                 bool manage_mixins);

```
void construct_mixin(mixin_id id);
```
```
void destroy_mixin(mixin_id id);
```

bool internal_implements(feature_id id, const internal::message_feature_tag &) const;

bool implements_message(feature_id id) const;
