public final class UsageEvents
extends Object implements Parcelable

A result returned from UsageStatsManager.queryEvents(long, long) from which to read UsageEvents.Event objects.

Summary

Nested classes
`class`	`UsageEvents.Event` An event representing a state change for a component.

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Fields
`public static final Creator<UsageEvents>`	`CREATOR`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`boolean`	`getNextEvent(UsageEvents.Event eventOut)` Retrieve the next `UsageEvents.Event` from the collection and put the resulting data into `eventOut`.
`boolean`	`hasNextEvent()` Returns whether or not there are more events to read using `getNextEvent(android.app.usage.UsageEvents.Event)`.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Inherited methods

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Fields

CREATOR

Added in API level 21

public static final Creator<UsageEvents> CREATOR

Public methods

describeContents

Added in API level 21

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getNextEvent

Added in API level 21

public boolean getNextEvent (UsageEvents.Event eventOut)

Retrieve the next UsageEvents.Event from the collection and put the resulting data into eventOut.

Parameters
`eventOut`	`UsageEvents.Event`: The `UsageEvents.Event` object that will receive the next event data.

Returns
`boolean`	true if an event was available, false if there are no more events.

hasNextEvent

Added in API level 21

public boolean hasNextEvent ()

Returns whether or not there are more events to read using getNextEvent(android.app.usage.UsageEvents.Event).

Returns
`boolean`	true if there are more events, false otherwise.

writeToParcel

Added in API level 21

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written. This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
