public final class Dataset
extends Object implements Parcelable

   ↳ android.service.autofill.Dataset

A dataset object represents a group of key/value pairs used to autofill parts of a screen.

In its simplest form, a dataset contains one or more key / value pairs (comprised of AutofillId and AutofillValue respectively); and one or more presentation for these pairs (a pair could have its own presentation, or use the default presentation associated with the whole dataset). When an autofill service returns datasets in a FillResponse and the screen input is focused in a view that is present in at least one of these datasets, the Android System displays a UI affordance containing the presentation of all datasets pairs that have that view's AutofillId. Then, when the user selects a dataset from the affordance, all views in that dataset are autofilled.

In a more sophisticated form, the dataset value can be protected until the user authenticates the dataset - see setAuthentication(IntentSender).

Public methods


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.

int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.


String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())

String a string representation of the object.


void writeToParcel (Parcel parcel, 
                int flags)

Flatten this object in to a Parcel.

parcel Parcel: The Parcel in which the object should be written.

flags int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
