public final class KeyedFrequencyCap
extends Object implements Parcelable


A frequency cap for a specific ad counter key.

Frequency caps define the maximum rate an event can occur within a given time interval. If the frequency cap is exceeded, the associated ad will be filtered out of ad selection.

Summary

Nested classes

class KeyedFrequencyCap.Builder

Builder for creating KeyedFrequencyCap objects. 

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<KeyedFrequencyCap> CREATOR

Public methods

int describeContents()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.

boolean equals(Object o)

Checks whether the KeyedFrequencyCap objects contain the same information.

int getAdCounterKey()

Returns the ad counter key that the frequency cap is applied to.

Duration getInterval()

Returns the interval, as a Duration which will be truncated to the nearest second, over which the frequency cap is calculated.

int getMaxCount()

Returns the maximum count of event occurrences allowed within a given time interval.

int hashCode()

Returns the hash of the KeyedFrequencyCap object's data.

String toString()

Returns a string representation of the object.

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

public static final Creator<KeyedFrequencyCap> CREATOR

Public methods

describeContents

Added in API level 35 

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(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

equals

Added in API level 35 

public boolean equals (Object o)

Checks whether the KeyedFrequencyCap objects contain the same information.

Parameters
o Object: the reference object with which to compare.
Returns
boolean true if this object is the same as the obj argument; false otherwise.

getAdCounterKey

public int getAdCounterKey ()

Returns the ad counter key that the frequency cap is applied to.

The ad counter key is defined by an adtech and is an arbitrary numeric identifier which defines any criteria which may have previously been counted and persisted on the device. If the on-device count exceeds the maximum count within a certain time interval, the frequency cap has been exceeded.

Returns
int This value cannot be null.

getInterval

public Duration getInterval ()

Returns the interval, as a Duration which will be truncated to the nearest second, over which the frequency cap is calculated.

When this frequency cap is computed, the number of persisted events is counted in the most recent time interval. If the count of previously occurring matching events for an adtech is greater than the number returned by getMaxCount(), the frequency cap has been exceeded, and the ad will not be eligible for ad selection.

Returns
Duration This value cannot be null.

getMaxCount

public int getMaxCount ()

Returns the maximum count of event occurrences allowed within a given time interval.

If there are more events matching the ad counter key and ad event type counted on the device within the time interval defined by getInterval(), the frequency cap has been exceeded, and the ad will not be eligible for ad selection.

For example, an ad that specifies a filter for a max count of two within one hour will not be eligible for ad selection if the event has been counted two or more times within the hour preceding the ad selection process.

Returns
int

hashCode

Added in API level 35 

public int hashCode ()

Returns the hash of the KeyedFrequencyCap object's data.

Returns
int a hash code value for this object.

toString

Added in API level 35 

public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

Added in API level 35 

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: 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 the following:
