Detailed Description

template<class Context, class Tag>
class cookmem::TLSContextProvider< Context, Tag >

Provides one shared, default-constructed context per Context, Tag, and thread.

Use a distinct Tag type to give different allocator groups separate contexts.

Member Typedef Documentation

context_type

template<class Context , class Tag >

typedef Context cookmem::TLSContextProvider< Context, Tag >::context_type

The type of the memory context.

is_always_equal

template<class Context , class Tag >

typedef std::false_type cookmem::TLSContextProvider< Context, Tag >::is_always_equal

Providers are equal only when they refer to the same context.

propagate_on_container_copy_assignment

template<class Context , class Tag >

typedef std::true_type cookmem::TLSContextProvider< Context, Tag >::propagate_on_container_copy_assignment

Containers take the allocator of the source when copy-assigned.

propagate_on_container_move_assignment

template<class Context , class Tag >

typedef std::true_type cookmem::TLSContextProvider< Context, Tag >::propagate_on_container_move_assignment

Containers take the allocator of the source when move-assigned.

propagate_on_container_swap

template<class Context , class Tag >

typedef std::true_type cookmem::TLSContextProvider< Context, Tag >::propagate_on_container_swap

Containers exchange allocators when swapped.

Constructor & Destructor Documentation

TLSContextProvider()

template<class Context , class Tag >

cookmem::TLSContextProvider< Context, Tag >::TLSContextProvider ( )

inline

Constructor. The provider refers to the active context of the current thread: the context of the innermost matching TLSContextScope if there is one, or the persistent thread-local context otherwise.

Member Function Documentation

get()

template<class Context , class Tag >

Context & cookmem::TLSContextProvider< Context, Tag >::get ( ) const

inline

Get the memory context.

Returns

the context this provider was bound to when it was constructed.

getActiveContext()

template<class Context , class Tag >

static Context & cookmem::TLSContextProvider< Context, Tag >::getActiveContext ( )

inlinestatic

Returns the active context, or the persistent thread context when no scope is active.

getThreadContext()

template<class Context , class Tag >

static Context & cookmem::TLSContextProvider< Context, Tag >::getThreadContext ( )

inlinestatic

Returns this thread's persistent context, even when a scope is active.

operator!=()

template<class Context , class Tag >

bool cookmem::TLSContextProvider< Context, Tag >::operator!= ( const TLSContextProvider< Context, Tag > &  other ) const

inline

Check if two providers refer to different memory contexts.

Parameters

other

the provider to compare with.

Returns

true if the providers refer to different contexts.

operator==()

template<class Context , class Tag >

bool cookmem::TLSContextProvider< Context, Tag >::operator== ( const TLSContextProvider< Context, Tag > &  other ) const

inline

Check if two providers refer to the same memory context.

Parameters

other

the provider to compare with.

Returns

true if both providers refer to the same context.
