The MediaKeySession interface of the Encrypted Media Extensions API represents a context for message exchange with a content decryption module (CDM).

Properties

closed → JSPromise<JSString>
The closed read-only property of the MediaKeySession interface returns a Promise signaling when a MediaKeySession closes. This promise can only be fulfilled and is never rejected. Closing a session means that licenses and keys associated with it are no longer valid for decrypting media data.
no setter
expiration → double
The expiration read-only property of the MediaKeySession interface returns the time after which the keys in the current session can no longer be used to decrypt media data, or NaN if no such time exists.
no setter
hashCode → int
The hash code for this object.
no setterinherited
keyStatuses → MediaKeyStatusMap
The keyStatuses read-only property of the MediaKeySession interface returns a reference to a read-only MediaKeyStatusMap of the current session's keys and their statuses.

getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
sessionId → String
The sessionId read-only property of the MediaKeySession interface contains a unique string generated by the content decryption module (CDM) for the current media object and its associated keys or licenses.
no setter

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
close() → JSPromise<JSAny?>
The close() method of the MediaKeySession interface notifies that the current media session is no longer needed, and that the content decryption module should release any resources associated with this object and close it. Then, it returns a Promise.
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
generateRequest(String initDataType, BufferSource initData) → JSPromise<JSAny?>
The generateRequest() method of the MediaKeySession interface returns a Promise after generating a media request based on initialization data.
load(String sessionId) → JSPromise<JSBoolean>
The load() method of the MediaKeySession interface returns a Promise that resolves to a boolean value after loading data for a specified session object.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
remove() → JSPromise<JSAny?>
The remove() method of the MediaKeySession interface returns a Promise after removing any session data associated with the current object.
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
toString() → String
A string representation of this object.
inherited
update(BufferSource response) → JSPromise<JSAny?>
The update() method of the MediaKeySession interface loads messages and licenses to the CDM, and then returns a Promise .

Operators

operator ==(Object other) → bool
The equality operator.
