A mechanism for ViewActions to specify what type of views they can operate on. A ViewAction can demand that the view passed to perform meets certain constraints. For example it may want to ensure the view is already in the viewable physical screen of the device or is of a certain type.

Returns
  • a Matcher that will be tested prior to calling perform.

Returns a description of the view action. The description should not be overly long and should fit nicely in a sentence like: "performing %description% action on view with id ..."

public void perform (UiController uiController, View view)

Performs this action on the given view.

Parameters
uiController the controller to use to interact with the UI.
view the view to act upon. never null.
