Detailed Description

template<typename T>
class etl::typed_storage_ext< T >

Wrapper class wraps a supplied memory area and lets the user create an instance of T in this memory at runtime. This class also erases the destructor call of T, i.e. if typed_storage goes out of scope, the destructor if the wrapped type will not be called. This can be done explicitly by calling destroy().

Template Parameters

T	Type of element stored in this instance of typed_storage.

Constructor & Destructor Documentation

~typed_storage_ext()

template<typename T>

etl::typed_storage_ext< T >::~typed_storage_ext ( )

inline

Default destructor which will NOT call the destructor of the object which was created by calling create().

Member Function Documentation

template<typename T>

template<typename T1>

reference etl::typed_storage_ext< T >::create ( const T1 & t1 )

inline

Constructs the instance of T with type T1

Returns

the instance of T which has been constructed in the external buffer.

create() [2/4]

template<typename T>

template<typename T1, typename T2>

reference etl::typed_storage_ext< T >::create ( const T1 & t1, const T2 & t2 )

inline

Returns

the instance of T which has been constructed in the external buffer.

create() [3/4]

template<typename T>

template<typename T1, typename T2, typename T3>

reference etl::typed_storage_ext< T >::create ( const T1 & t1, const T2 & t2, const T3 & t3 )

inline

Constructs the instance of T with types T1, T2, T3

Returns

the instance of T which has been constructed in the external buffer.

has_value()

template<typename T>

bool etl::typed_storage_ext< T >::has_value ( ) const

inline

Returns

true if object has been constructed using create().

false otherwise.

operator*() [1/2]

template<typename T>

const_reference etl::typed_storage_ext< T >::operator* ( ) const

inline

Returns

const_reference of type T and asserts if has_value() is false.

operator*() [2/2]

template<typename T>

reference etl::typed_storage_ext< T >::operator* ( )

inline

Returns

reference of type T and asserts if has_value() is false.

operator->() [1/2]

template<typename T>

const_pointer etl::typed_storage_ext< T >::operator-> ( ) const

inline

Returns

a const pointer of type T and asserts if has_value() is false.

operator->() [2/2]

template<typename T>

pointer etl::typed_storage_ext< T >::operator-> ( )

inline

Returns

a pointer of type T and asserts if has_value() is false.
