ContextInsight


public abstract class ContextInsight
extends Object

java.lang.Object
   ↳ android.app.personalcontext.insight.ContextInsight


A ContextInsight is the result of an understander examining one or more ContextHints. It represents something that can be shown to a user, and potentially acted upon. Insights are forwarded on to renderers, which are responsible for showing them to the user.

This is an abstract base class for all insights. Only built-in insight classes are supported. Users of this class can use instanceof to determine the type of the insight.

Summary

Public methods

boolean equals(Object o)

final InsightBranding getBranding()

Gets branding information for this insight.

final Instant getCreationTime()

Gets the time this hint was created.

final UUID getInsightId()

Returns the unique identifier for this insight.

int hashCode()

Returns a hash code value for the object.

String toString()

equals

Added in version 37.2
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 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
o Object: the reference object with which to compare.

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

getBranding

Added in version 37.2
public final InsightBranding getBranding ()

Gets branding information for this insight.

Returns
InsightBranding

getCreationTime

Added in version 37.2
public final Instant getCreationTime ()

Gets the time this hint was created.

Returns
Instant

getInsightId

Added in version 37.2
public final UUID getInsightId ()

Returns the unique identifier for this insight.

Returns
UUID

hashCode

Added in version 37.2
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.

toString

Added in version 37.2
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.
