packet

A homogeneous container that can contain one of several types that are all inherited from the same base class.

etl::packet<typename TBase, size_t SIZE, size_t ALIGNMENT>

Template parameters

TBase
 The base class for all objects. The destructor must be virtual.

SIZE
 The size of the largest type.

ALIGNMENT
 The largest alignment of all of the types.

Member types

base_t = TBase

Contructors

C++03

template <typename T>
explicit packet(const T& value)

C++11

template <typename T>
explicit packet(T&& value)

Description
Constructs an object of type T with the supplied value.
Static asserts on any type that does not derive from TBase.
Static asserts on any type that does not conform to the maximum size and alignment.

Destructor

~packet()

Description
Destructs the contained object

Operators

C++03

template <typename T>
packet& operator =(const T& value)

C++11

template <typename T>
packet& operator =(T&& value)

Description
Assigns a new object to the packet. The previous object is destructed.

Access

const TBase& get() const

Description
Returns a const reference to the contained object.
