TvContentRating

Kotlin |Java

public final class TvContentRating
extends Object

java.lang.Object
↳	android.media.tv.TvContentRating

A class representing a TV content rating. When a TV input service inserts the content rating information on a program into the database, this class can be used to generate the formatted string for TvContract.Programs.COLUMN_CONTENT_RATING. To create a TvContentRating object, use the TvContentRating.createRating method with valid rating system string constants.

It is possible for an application to define its own content rating system by supplying a content rating system definition XML resource (see example below) and declaring a broadcast receiver that filters TvInputManager.ACTION_QUERY_CONTENT_RATING_SYSTEMS in its manifest.

Example: Rating system definition for the TV Parental Guidelines

The following XML example shows how the TV Parental Guidelines in the United States can be defined:

 <rating-system-definitions xmlns:android="http://schemas.android.com/apk/res/android"

System defined rating strings

The following strings are defined by the system to provide a standard way to create TvContentRating objects.

For example, to create an object that represents TV-PG rating with suggestive dialogue and coarse language from the TV Parental Guidelines in the United States, one can use the following code snippet:

 TvContentRating rating = TvContentRating.createRating(
         "com.android.tv",
         "US_TV",
         "US_TV_PG",
         "US_TV_D", "US_TV_L");

Fields

UNRATED

Added in API level 23

public static final TvContentRating UNRATED

Rating constant denoting unrated content. Used to handle the case where the content rating information is missing.

TV input services can call TvInputManager.isRatingBlocked with this constant to determine whether they should block unrated content. The subsequent call to TvInputService.Session.notifyContentBlocked with the same constant notifies applications that the current program content is blocked by parental controls.

Public methods

contains

Added in API level 24

public boolean contains (TvContentRating rating)

Returns true if this rating has the same main rating as the specified rating and when this rating's sub-ratings contain the other's.

For example, a TvContentRating object that represents TV-PG with S(Sexual content) and V(Violence) contains TV-PG, TV-PG/S, TV-PG/V and itself.

Parameters
`rating`	`TvContentRating`: The `TvContentRating` to check. This value cannot be `null`.

Returns
`boolean`	`true` if this object contains `rating`, `false` otherwise.

createRating

Added in API level 21

public static TvContentRating createRating (String domain, 
                String ratingSystem, 
                String rating, 
                String... subRatings)

Creates a TvContentRating object with predefined content rating strings.

Parameters
`domain`	`String`: The domain string. For example, "com.android.tv".
`ratingSystem`	`String`: The rating system string. For example, "US_TV".
`rating`	`String`: The content rating string. For example, "US_TV_PG".
`subRatings`	`String`: The sub-rating strings. For example, "US_TV_D" and "US_TV_L".

Returns
`TvContentRating`	A `TvContentRating` object.

Throws
`IllegalArgumentException`	If `domain`, `ratingSystem` or `rating` is `null`.

equals

Added in API level 21

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`: the reference object with which to compare.

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

flattenToString

Added in API level 21

public String flattenToString ()

Returns a string that unambiguously describes the rating information contained in a TvContentRating object. One can later recover the object from this string through unflattenFromString(String).

Returns
`String`	a string containing the rating information, which can later be stored in the database.

See also:

unflattenFromString(String)

getDomain

Added in API level 21

public String getDomain ()

Returns the domain of this TvContentRating object.

Returns
`String`

getMainRating

Added in API level 21

public String getMainRating ()

Returns the main rating of this TvContentRating object.

Returns
`String`

getRatingSystem

Added in API level 21

public String getRatingSystem ()

Returns the rating system of this TvContentRating object.

Returns
`String`

getSubRatings

Added in API level 21

public List<String> getSubRatings ()

Returns the unmodifiable sub-rating string List of this TvContentRating object.

Returns
`List<String>`

hashCode

Added in API level 21

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.

unflattenFromString

Added in API level 21

public static TvContentRating unflattenFromString (String ratingString)

Recovers a TvContentRating object from the string that was previously created from flattenToString().

Parameters
`ratingString`	`String`: The string returned by `flattenToString()`.

Returns
`TvContentRating`	the `TvContentRating` object containing the domain, rating system, rating and sub-ratings information encoded in `ratingString`.
