See Also: Inherited members from Java.Lang.Object

Public Constructors

	Semaphore(int)	Creates a `Semaphore` with the given number of permits and nonfair fairness setting.
	Semaphore(int, bool)	Creates a `Semaphore` with the given number of permits and the given fairness setting.

Protected Constructors

Semaphore(IntPtr, Android.Runtime.JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Public Properties

[read-only]	HasQueuedThreads	bool. Queries whether any threads are waiting to acquire.
[read-only]	IsFair	bool. Returns `true` if this semaphore has fairness set true.
[read-only]	QueueLength	int. Returns an estimate of the number of threads waiting to acquire.

Protected Properties

[read-only]	QueuedThreads	ICollection<Java.Lang.Thread>. Returns a collection containing threads that may be waiting to acquire.
[read-only] override	ThresholdClass	IntPtr. This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
[read-only] override	ThresholdType	Type. This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.

Public Methods

	Acquire() Acquires a permit from this semaphore, blocking until one is available, or the thread is `Java.Lang.Thread.Interrupt`.
	Acquire(int) Acquires the given number of permits from this semaphore, blocking until all are available, or the thread is `Java.Lang.Thread.Interrupt`.
	AcquireUninterruptibly() Acquires a permit from this semaphore, blocking until one is available.
	AcquireUninterruptibly(int) Acquires the given number of permits from this semaphore, blocking until all are available.
	AvailablePermits() : int Returns the current number of permits available in this semaphore.
	DrainPermits() : int Acquires and returns all permits that are immediately available.
	Release() Releases a permit, returning it to the semaphore.
	Release(int) Releases the given number of permits, returning them to the semaphore.
	TryAcquire() : bool Acquires a permit from this semaphore, only if one is available at the time of invocation.
	TryAcquire(int) : bool Acquires the given number of permits from this semaphore, only if all are available at the time of invocation.
	TryAcquire(long, TimeUnit) : bool Acquires a permit from this semaphore, if one becomes available within the given waiting time and the current thread has not been `Java.Lang.Thread.Interrupt`.
	TryAcquire(int, long, TimeUnit) : bool Acquires the given number of permits from this semaphore, if all become available within the given waiting time and the current thread has not been `Java.Lang.Thread.Interrupt`.

Protected Methods

ReducePermits(int)

Shrinks the number of available permits by the indicated reduction.
