Person


public final class Person
extends Object implements Parcelable

java.lang.Object
   ↳ android.app.Person


Provides an immutable reference to an entity that appears repeatedly on different surfaces of the platform. For example, this could represent the sender of a message.

Fields

CREATOR

Added in API level 28
public static final Creator<Person> CREATOR

Public methods

describeContents

Added in API level 28
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

Added in API level 28
public boolean equals (Object obj)

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 return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

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
obj Object: This value may be null.

Returns
boolean true if this object is the same as the obj argument; false otherwise.

getIcon

Added in API level 28
public Icon getIcon ()

Returns
Icon the icon provided for this person or null if no icon was provided.

getKey

Added in API level 28
public String getKey ()

Returns
String the key provided for this person or null if no key was provided.

getName

Added in API level 28
public CharSequence getName ()

Returns
CharSequence the name provided for this person or null if no name was provided.

getUri

Added in API level 28
public String getUri ()

Returns
String the uri provided for this person or null if no Uri was provided.

hashCode

Added in API level 28
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 in equals 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 the hashCode 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 the hashCode 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.

isBot

Added in API level 28
public boolean isBot ()

Returns
boolean whether this Person is a machine.

isImportant

Added in API level 28
public boolean isImportant ()

Returns
boolean whether this Person is important.

toBuilder

Added in API level 28
public Person.Builder toBuilder ()

Creates and returns a new Builder initialized with this Person's data.

Returns
Person.Builder

writeToParcel

Added in API level 28
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written. This value cannot be null.

flags int: Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
