folly::ThreadLocalPtr

Synopsis

Declared in <folly/ThreadLocal.h>

template<
    class T,
    class Tag = void,
    class AccessMode = void>
class ThreadLocalPtr;

Description

Has semantics similar to boost::thread_specific_ptr: each thread sees an independent pointer, and the pointed-to object is deleted when the thread exits or the pointer is reset. Tag groups instances that share a pthread_key_t, and AccessMode selects the access mode for iterating all threads.

Types

`Accessor`	Iterable view over the values held for all threads.
