VerifiedDisplayHash
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
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
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
public String getHashAlgorithm ()
The selected hash algorithm that generated the image hash.
| Returns | |
|---|---|
String |
This value cannot be null. |
getImageHash
public byte[] getImageHash ()
The image hash generated when creating the DisplayHash.
| Returns | |
|---|---|
byte[] |
This value cannot be null. |
getTimeMillis
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
public 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())
| Returns | |
|---|---|
String |
a string representation of the 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 |
