Properties
-
closed
→ JSPromise<
JSString> -
The
closed
read-only property of the MediaKeySession interface returns aPromise
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 Closing a session means that licenses and keys associated with it are no longer valid for decrypting media data.no setter - expiration → double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.no setter - onkeystatuseschange ↔ EventHandler?

- onmessage ↔ EventHandler?
-
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 aPromise
. -
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 withdispatchEvent()
.inherited -
generateRequest(
String initDataType, BufferSource initData) → JSPromise< JSAny?> -
The
generateRequest()
method of the MediaKeySession interface returns aPromise
after generating a media request based on initialization data. -
load(
String sessionId) → JSPromise< JSBoolean> -
The
load()
method of the MediaKeySession interface returns aPromise
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 aPromise
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 aPromise
.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
