## Public constructors

### AdapterDataLoaderAction

    AdapterDataLoaderAction (Matcher<? extends Object> dataToLoadMatcher,
                    Optional<Integer> atPosition,
                    AdapterViewProtocol adapterViewProtocol)

Parameters
`dataToLoadMatcher` | `Matcher`
`atPosition` | `Optional`
`adapterViewProtocol` | `AdapterViewProtocol`

## Public methods

### getAdaptedData

    AdapterViewProtocol.AdaptedData getAdaptedData ()

Returns
`AdapterViewProtocol.AdaptedData` |

### getConstraints

    Matcher<View> getConstraints ()

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
`Matcher<View>` | a `Matcher` that will be tested prior to calling perform.

### getDescription

    String getDescription ()

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 ..."

Returns
`String` |

### perform

    void perform (UiController uiController,
                    View view)

Performs this action on the given view.

Parameters
`uiController` | `UiController`: the controller to use to interact with the UI.
`view` | `View`: the view to act upon. never null.
