Instance Properties

Defined in webdriver.promise.Node_

This node's parent.

Defined in webdriver.promise.Deferred

Represents the eventual value of a completed operation. Each promise may be in one of three states: pending, resolved, or rejected. Each promise starts in the pending state and may make a single transition to either a fulfilled or rejected state, at which point the promise is considered resolved.
