VerifiedDisplayHash


public final class VerifiedDisplayHash
extends Object implements Parcelable

java.lang.Object
   ↳ android.view.displayhash.VerifiedDisplayHash


The verified display hash used to validate information about what was present on screen.

Summary

Inherited constants

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<VerifiedDisplayHash> CREATOR

Public constructors

VerifiedDisplayHash(long timeMillis, Rect boundsInWindow, String hashAlgorithm, byte[] imageHash)

Creates a new VerifiedDisplayHash.

Public methods

int describeContents()

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

Rect getBoundsInWindow()

The bounds of the requested area to generate the hash.

String getHashAlgorithm()

The selected hash algorithm that generated the image hash.

byte[] getImageHash()

The image hash generated when creating the DisplayHash.

long getTimeMillis()

The timestamp when the hash was generated.

String toString()

Returns a string representation of the object.

void writeToParcel(Parcel dest, int flags)

Flatten this object in to a Parcel.

Inherited methods

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.

abstract int describeContents()

Public constructors

VerifiedDisplayHash

Added in API level 31
public VerifiedDisplayHash (long timeMillis, 
                Rect boundsInWindow, 
                String hashAlgorithm, 
                byte[] imageHash)

Creates a new VerifiedDisplayHash.

Parameters
timeMillis long: The timestamp when the hash was generated. Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

boundsInWindow Rect: The bounds of the requested area to generate the hash. This is in window space passed in by the client. This value cannot be null.

hashAlgorithm String: The selected hash algorithm that generated the image hash. This value cannot be null.

imageHash byte: The image hash generated when creating the DisplayHash. This value cannot be null.

Public methods

describeContents

Added in API level 31
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

getBoundsInWindow

Added in API level 31
public Rect getBoundsInWindow ()

The bounds of the requested area to generate the hash. This is in window space passed in by the client.

Returns
Rect This value cannot be null.

getHashAlgorithm

Added in API level 31
public String getHashAlgorithm ()

The selected hash algorithm that generated the image hash.

Returns
String This value cannot be null.

getImageHash

Added in API level 31
public byte[] getImageHash ()

The image hash generated when creating the DisplayHash.

Returns
byte[] This value cannot be null.

getTimeMillis

Added in API level 31
public long getTimeMillis ()

The timestamp when the hash was generated.
Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

Returns
long Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

toString

Added in API level 31
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

Added in API level 31
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
