RTCPeerConnection: pendingLocalDescription property
The pendingLocalDescription
read-only property of the RTCPeerConnection
interface returns an RTCSessionDescription
object describing a pending configuration change for the local end of the connection.
This does not describe the connection as it currently stands, but as it may exist in the near future.
Use RTCPeerConnection.currentLocalDescription
or RTCPeerConnection.localDescription
to get the current state of the endpoint.
For details on the difference, see Pending and current descriptions in the WebRTC Connectivity page.
Value
If a local description change is in progress, this is an RTCSessionDescription
describing the proposed configuration.
Otherwise, this returns null
.
Examples
This example looks at the pendingLocalDescription
to determine whether or not there's a description change being processed.
const pc = new RTCPeerConnection();
// ...
const sd = pc.pendingLocalDescription;
if (sd) {
// There's a description change underway!
} else {
// No description change pending
}
