Detailed Description

template<class Mutex>
struct folly::detail::LockTraitsImpl< Mutex, MutexLevel::SHARED, true >

Note that there is no deadly diamond here because all the structs only have static functions and static bools which are going to be overridden by the lowest level implementation

Member Function Documentation

template<class Mutex >

template<class Rep , class Period >

static bool folly::detail::LockTraitsImpl< Mutex, MutexLevel::SHARED, true >::try_lock_for ( Mutex &  mutex, const std::chrono::duration< Rep, Period > &  timeout  )

inlinestatic

Acquire the lock exclusively, with a timeout.

Returns true or false indicating if the lock was acquired or not.

                                                     {
    return mutex.try_lock_for(timeout);
  }

template<class Rep , class Period >

static bool folly::detail::LockTraitsImpl< Mutex, MutexLevel::SHARED, true >::try_lock_shared_for ( Mutex &  mutex, const std::chrono::duration< Rep, Period > &  timeout  )

inlinestatic

Acquire the lock in shared (read) mode, with a timeout.

Returns true or false indicating if the lock was acquired or not.

Definition at line 311 of file LockTraits.h.
