◆ Enter() [1/2]

static ASPOSECPP_SHARED_API void System::Threading::Monitor::Enter ( const SharedPtr< Object > & obj )

static

Acquires an exclusive lock on a specified object.

Parameters

obj	The object on which to acquire the monitor lock.

Exceptions

ArgumentNullException The obj parameter is null.

◆ Enter() [2/2]

static ASPOSECPP_SHARED_API void System::Threading::Monitor::Enter	(	const System::SharedPtr< Object > &	obj,
		bool &	lockTaken
	)

static

Acquires an exclusive lock on the specified object, and atomically sets a value that indicates whether the lock was taken

◆ Exit()

static ASPOSECPP_SHARED_API void System::Threading::Monitor::Exit ( const SharedPtr< Object > & obj )

static

Releases an exclusive lock on the specified object.

Parameters

obj	The object on which to release the lock.

Exceptions

ArgumentNullException	The obj parameter is null.
SynchronizationLockException	The current thread does not own the lock for the specified object.

◆ IsEntered()

static ASPOSECPP_SHARED_API bool System::Threading::Monitor::IsEntered ( const System::SharedPtr< Object > & obj )

static

Determines whether the current thread holds the lock on the specified object.

◆ Pulse()
