extends Object
implements
Parcelable
java.lang.Object | |
↳ | android.adservices.ondevicepersonalization.EventLogRecord |
Data to be logged in the EVENTS table.
Each record in the EVENTS table is associated with one row from an existing
RequestLogRecord
in the requests table RequestLogRecord.getRows()
.
The purpose of the EVENTS table is to add supplemental information to logged data
from a prior request, e.g., logging an event when a link in a rendered WebView is
clicked IsolatedWorker#onEvent(EventInput, android.os.OutcomeReceiver)
.
The contents of the EVENTS table can be
consumed by Federated Learning facilitated model training, or Federated Analytics facilitated
cross-device statistical analysis.

Public methods
describeContents
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 |
equals
public boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation
on non-null object references:
- It is reflexive: for any non-null reference value
x
,x.equals(x)
should returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
Parameters | |
---|---|
o |
Object : This value may be null . |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getData
public ContentValues getData ()
Additional data to be logged. Can be null if no additional data needs to be written as part of the event, and only the occurrence of the event needs to be logged.
Returns | |
---|---|
ContentValues |
getRequestLogRecord
public RequestLogRecord getRequestLogRecord ()
The existing RequestLogRecord
that this payload should be associated with. In an
implementation of
IsolatedWorker.onExecute(ExecuteInput, android.os.OutcomeReceiver)
, this should be
set to a value returned by LogReader.getRequests(Instant, Instant)
. In an
implementation of IsolatedWorker.onEvent(EventInput, android.os.OutcomeReceiver)
,
this should be set to null
because the payload will be automatically associated with
the current RequestLogRecord
.
Returns | |
---|---|
RequestLogRecord |
getRowIndex
public int getRowIndex ()
The index of the row in an existing RequestLogRecord
that this payload should be
associated with.
Returns | |
---|---|
int |
Value is 0 or greater |
getTime
public Instant getTime ()
Returns the timestamp of this record.
Returns | |
---|---|
Instant |
This value cannot be null . |
getType
public int getType ()
The service-assigned identifier that identifies this payload. Each row in
RequestLogRecord
can be associated with up to one event of a specified type.
The platform drops events if another event with the same type already exists for a row
in RequestLogRecord
. Must be >0 and <128. This allows up to 127 events to be
written for each row in RequestLogRecord
. If unspecified, the default is 1.
Returns | |
---|---|
int |
Value is between 1 and 127 inclusive |
hashCode
public int hashCode ()
Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
HashMap
.
The general contract of hashCode
is:
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCode
method must consistently return the same integer, provided no information used inequals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals
method, then calling thehashCode
method on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
equals
method, then calling thehashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns | |
---|---|
int |
a hash code value for this object. |
writeToParcel
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 Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
