MediaRouteSelector

public final class MediaRouteSelector
extends Object

java.lang.Object
   ↳ android.support.v7.media.MediaRouteSelector


Describes the capabilities of routes that applications would like to discover and use.

This object is immutable once created using a MediaRouteSelector.Builder instance.

Example

 MediaRouteSelector selectorBuilder = new MediaRouteSelector.Builder()
         .addControlCategory(MediaControlIntent.CATEGORY_LIVE_VIDEO)
         .addControlCategory(MediaControlIntent.CATEGORY_REMOTE_PLAYBACK)
         .build();

 MediaRouter router = MediaRouter.getInstance(context);
 router.addCallback(selector, callback, MediaRouter.CALLBACK_FLAG_REQUEST_DISCOVERY);
 

Summary

Nested classes

class MediaRouteSelector.Builder

Builder for media route selectors

Fields

public static final MediaRouteSelector EMPTY

An empty media route selector that will not match any routes.

Public methods

Bundle asBundle()

Converts this object to a bundle for serialization.

boolean contains(MediaRouteSelector selector)

Returns true if this selector contains all of the capabilities described by the specified selector.

boolean equals(Object o)

Indicates whether some other object is "equal to" this one.

static MediaRouteSelector fromBundle(Bundle bundle)

Creates an instance from a bundle.

List<String> getControlCategories()

Gets the list of media control categories in the selector.

boolean hasControlCategory(String category)

Returns true if the selector contains the specified category.

int hashCode()

Returns a hash code value for the object.

boolean isEmpty()

Returns true if the selector does not specify any capabilities.

boolean isValid()

Returns true if the selector has all of the required fields.

boolean matchesControlFilters(List<IntentFilter> filters)

Returns true if the selector matches at least one of the specified control filters.

String toString()

Returns a string representation of the object.

Inherited methods

From class java.lang.Object

Fields

EMPTY

MediaRouteSelector EMPTY

An empty media route selector that will not match any routes.

Public methods

asBundle

Bundle asBundle ()

Converts this object to a bundle for serialization.

Returns
Bundle The contents of the object represented as a bundle.

contains

boolean contains (MediaRouteSelector selector)

Returns true if this selector contains all of the capabilities described by the specified selector.

Parameters
selector MediaRouteSelector: The selector to be examined.
Returns
boolean True if this selector contains all of the capabilities described by the specified selector.

equals

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.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

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.

fromBundle

MediaRouteSelector fromBundle (Bundle bundle)

Creates an instance from a bundle.

Parameters
bundle Bundle: The bundle, or null if none.
Returns
MediaRouteSelector The new instance, or null if the bundle was null.

getControlCategories

List<String> getControlCategories ()

Gets the list of media control categories in the selector.

Returns
List<String> The list of categories.

hasControlCategory

boolean hasControlCategory (String category)

Returns true if the selector contains the specified category.

Parameters
category String: The category to check.
Returns
boolean True if the category is present.

hashCode

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(Object) 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(java.lang.Object) 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.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Returns
int a hash code value for this object.

isEmpty

boolean isEmpty ()

Returns true if the selector does not specify any capabilities.

Returns
boolean

isValid

boolean isValid ()

Returns true if the selector has all of the required fields.

Returns
boolean

matchesControlFilters

boolean matchesControlFilters (List<IntentFilter> filters)

Returns true if the selector matches at least one of the specified control filters.

Parameters
filters List: The list of control filters to consider.
Returns
boolean True if a match is found.

toString

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.
