Remarks

A state object for collecting statistics such as count, min, max, sum, and average.

This class is designed to work with (though does not require) java.util.stream streams. For example, you can compute summary statistics on a stream of ints with:

{@code
            IntSummaryStatistics stats = intStream.collect(IntSummaryStatistics::new,
                                                           IntSummaryStatistics::accept,
                                                           IntSummaryStatistics::combine);
            }

IntSummaryStatistics can be used as a java.util.stream.Stream#collect(Collector) reduction target for a java.util.stream.Stream stream. For example:

{@code
            IntSummaryStatistics stats = people.stream()
                                               .collect(Collectors.summarizingInt(Person::getDependents));
            }

This computes, in a single pass, the count of people, as well as the minimum, maximum, sum, and average of their number of dependents.

Constructors

IntSummaryStatistics()	Constructs an empty instance with zero count, zero sum, `Integer.MAX_VALUE` min, `Integer.MIN_VALUE` max and zero average.
IntSummaryStatistics(Int64, Int32, Int32, Int64)	Constructs a non-empty instance with the specified `count`, `min`, `max`, and `sum`.
IntSummaryStatistics(IntPtr, JniHandleOwnership)

Properties

Average	Returns the arithmetic mean of values recorded, or zero if no values have been recorded.
Class	Returns the runtime class of this `Object`. (Inherited from Object)
Count	Returns the count of values recorded.
Handle	The handle to the underlying Android instance. (Inherited from Object)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
Max	Returns the maximum value recorded, or `Integer.MIN_VALUE` if no values have been recorded.
Min	Returns the minimum value recorded, or `Integer.MAX_VALUE` if no values have been recorded.
PeerReference	(Inherited from Object)
Sum	Returns the sum of values recorded, or zero if no values have been recorded.
ThresholdClass
ThresholdType

Methods

Clone()	Creates and returns a copy of this object. (Inherited from Object)
Combine(IntSummaryStatistics)	Combines the state of another `IntSummaryStatistics` into this one.
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
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)
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)
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 it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
