Keycloak.java events are instead exposed as void methods

[niloc132]

While technically an instance of Keycloak would have a function assigned to its onTokenExpired field, these are intended to be used as event handlers.

See https://www.keycloak.org/docs/latest/securing_apps/#callback-events for documentation on how they are intended to be used.

For example,

domino-keycloak/src/main/java/org/dominokit/keycloak/Keycloak.java

Line 87 in b6828ab

public native void onTokenExpired();

could be a field or getter/setter method pair, of some @JsFunction type

@JsFunction
@FunctionalInterface
public interface EventCallback {
  void invoke();
}

Keycloak.java

public EventCallback onTokenExpired;

Then, it can be assigned with a lambda/etc, so that the token can be refreshed:

// from https://stackoverflow.com/a/57855752/860630
keycloak.onTokenExpired = () -> {
  keycloak.updateToken(30);
  //TODO handle errors to return to login screen...
};
