Detailed Description

template<typename T, bool = (sizeof(T)<=sizeof(T*) && is_basic<T>::value)>
class stapl::immutable_reference_wrapper< T, bool >

Wraps a reference to a temporarily immutable object.

Template Parameters

T	Object type.

Referents of immutable references may avoid serialization when communication happens in shared memory. The referent must not be deleted or mutated until all immutable_reference_wrapper to it have been deleted. This is commonly guaranteed with synchronization.

Once all the immutable_reference_wrapper objects have been destroyed, then the referenced object can be mutated or deleted.
