Detailed Description

template<typename T>
class stapl::location_specific_storage< T >

Supports global objects in the presence of locations.

All non-const global object have to be declared as location_specific_storage objects, since locations are effectively virtual threads. This class is modeled after boost::thread_specific_ptr.

Global const variables do not have to be instances of location_specific_storage, since the latter imposes some additional overhead.

Member Function Documentation

get()

template<typename T >

T& stapl::location_specific_storage< T >::get

(

void

)

const

Returns the stored T object.

If a stored object T has not been created yet, it will be created with any arguments given through location_specific_storage(Args&&...).

try_get()

template<typename T >

T* stapl::location_specific_storage< T >::try_get

(

void

)

const

Attempts to return the stored T object.

If a stored object T has not been created yet, it returns nullptr.
