requestWidgetToken
boolean requestWidgetToken(
IWidgetTokenKeeper requester,
int priority)
- Requests the widget token from this token owner. Returns
true
if the token has been acquired or is
already owned by the requester. This method is non-blocking.
priority
is forwarded to any existing token keeper
to give it an estimate on whether the request has higher priority than
the current keeper's. There is, however, no guarantee that another keeper
will release the token even if it has a high priority.
