Detailed Description

Abstract base class for lock guard implementations.

Provides the interface for RAII-style lock management including:

• Various locking policies (automatic, manual, try-lock)
• Lock/unlock functionality
• Lock state query

Member Enumeration Documentation

lockPolicy

enum class original::lockGuard::lockPolicy

strong

Locking policies for guard construction.

Enumerator
MANUAL_LOCK	Don't lock automatically.
AUTO_LOCK	Lock immediately on construction.
TRY_LOCK	Try to lock immediately on construction.
ADOPT_LOCK	Assume lock is already held.

Member Function Documentation

isLocked()

virtual bool original::lockGuard::isLocked ( ) const

protectedpure virtualnoexcept

Checks if the guard currently holds the lock.

Returns

true if locked, false otherwise

Implemented in original::uniqueLock, and original::multiLock< MUTEX >.

lock()

virtual void original::lockGuard::lock ( )

protectedpure virtual

Locks the associated mutex(es)

Exceptions

sysError

if the lock operation fails

Implemented in original::uniqueLock, and original::multiLock< MUTEX >.

tryLock()

virtual bool original::lockGuard::tryLock ( )

protectedpure virtual

Attempts to lock the associated mutex(es) without blocking.

Returns

true if lock was acquired, false otherwise

Exceptions

sysError

if the operation fails

Implemented in original::uniqueLock, and original::multiLock< MUTEX >.

unlock()

virtual void original::lockGuard::unlock ( )

protectedpure virtual

Unlocks the associated mutex(es)

Exceptions

sysError

if the unlock operation fails

Implemented in original::uniqueLock, and original::multiLock< MUTEX >.
