IsPresent	Return `true` if there is a value present, otherwise `false`.
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)

Methods

Clone()	Creates and returns a copy of this object. (Inherited from Object)
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
Empty()	Returns an empty `OptionalLong` instance.
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
IfPresent(ILongConsumer)	Have the specified consumer accept the value if a value is present, otherwise do nothing.
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
Notify()	Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object)
NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
Of(Int64)	Return an `OptionalLong` with the specified value present.
OrElse(Int64)	Return the value if present, otherwise return `other`.
OrElseGet(ILongSupplier)	Return the value if present, otherwise invoke `other` and return the result of that invocation.
OrElseThrow(ISupplier)	Return the contained value, if present, otherwise throw an exception to be created by the provided supplier.
SetHandle(IntPtr, JniHandleOwnership)	Sets the Handle property. (Inherited from Object)
ToArray<T>()	(Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
UnregisterFromRuntime()	(Inherited from Object)
Wait()	Causes the current thread to wait until another thread invokes the `java.lang.Object#notify()` method or the `java.lang.Object#notifyAll()` method for this object. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until either another thread invokes the `java.lang.Object#notify()` method or the `java.lang.Object#notifyAll()` method for this object, or a specified amount of time has elapsed. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until another thread invokes the `java.lang.Object#notify()` method or the `java.lang.Object#notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
