Types ¶
type DemoteMutex ¶
type DemoteMutex struct {
// contains filtered or unexported fields
}
DemoteMutex is a DemoteMutex that allows 'demotion' - a writelock will demote such that readlocks are able to acquite the mutex, but other writelocks are still blocked.
func (*DemoteMutex) Demote ¶
func (dm *DemoteMutex) Demote()
Demote will modify a writelocked DemoteMutex such that readlocks can acquire the mutex but writelocks are still blocked. After being demoted, the DemoteMutex must be unlocked by calling 'DemotedUnlock'.
func (*DemoteMutex) DemotedUnlock ¶
func (dm *DemoteMutex) DemotedUnlock()
DemotedUnlock will fully unlock a lock that has been demoted.
func (*DemoteMutex) Lock ¶
func (dm *DemoteMutex) Lock()
Lock will grab a writelock on a DemoteMutex. A writelocked DemoteMutex can be demoted such that readlocks can aquire the mutex but other writelocks are still blocked.
func (*DemoteMutex) RLock ¶
func (dm *DemoteMutex) RLock()
RLock will grab a readlock on the DemoteMutex. RLock can share the mutex with demoted locks.
func (*DemoteMutex) RUnlock ¶
func (dm *DemoteMutex) RUnlock()
RUnlock will release a readlock on the DemoteMutex.
func (*DemoteMutex) Unlock ¶
func (dm *DemoteMutex) Unlock()
Unlock will fully unlock a DemoteMutex.
