Detailed Description

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

Wrapper class that provides a 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()

template<typename T >

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

inline

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

Member Function Documentation

create() [1/4]

template<typename T >

template<typename T1 >

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

inline

Constructs the instance of T with type T1 asserts if has_value() is false.

Returns

the instance of T which has been constructed in the internal byte array.

create() [2/4]

template<typename T >

template<typename T1 , typename T2 >

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

inline

Returns

the instance of T which has been constructed in the internal byte array.

create() [3/4]

template<typename T >

template<typename T1 , typename T2 , typename T3 >

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

inline

create() [4/4]

template<typename T >

template<typename T1 , typename T2 , typename T3 , typename T4 >

reference etl::typed_storage< T >::create ( const T1 &  t1, const T2 &  t2, const T3 &  t3, const T4 &  t4  )

inline

Constructs the instance of T with types T1, T2, T3, T4 asserts if has_value() is false.

Returns

the instance of T which has been constructed in the internal byte array.

has_value()

template<typename T >

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

inline

Returns

true if object has been constructed using create().

false otherwise.

operator*() [1/2]

template<typename T >

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

inline

Returns

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

operator*() [2/2]

template<typename T >

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

inline

Returns

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

operator->() [1/2]

template<typename T >

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

inline

Returns

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

operator->() [2/2]

template<typename T >

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

inline

Returns

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