Methods
_addListeners
()
private
Wire up our events listeners.
_destroyIndicators
()
private
On destroy, run destroy on any indicator instances we have. This is a method so we can hook up and test that it's called vs a closure in the init.
_initIndicatorManager
()
private
Init during class initialization. Add _indicators and catch destroy event to clean up indicator instances.
_renderUI
()
To prevent having to force call sites to pass in parentNode, we must override YUI's built-in _renderUI method.
This is a copy of the YUI method, except for using our own parentNode. This is needed so the spinner overlays correctly.
bindUI
()
Sets up event listeners.
error
()
Method called to clear overlay on error.
