Class Overview

Base class for implementations that wrap a given DataAdapter, passing through all method calls to it with the exception of notifyDataChanged(), addOnDataChangedListener(OnDataChangedListener) and removeOnDataChangedListener(OnDataChangedListener).

For data changed notifications, this DataAdapterWrapper registers itself as an com.shinobicontrols.charts.DataAdapter.OnDataChangedListener of the wrapped DataAdapter. By maintaining its own list of com.shinobicontrols.charts.DataAdapter.OnDataChangedListeners it is able to notify these when it receives a notification from the wrapped DataAdapter.

Consequently this retains the notification policy of the wrapped DataAdapter regardless of whether data points are added/removed/etc. to and from this DataAdapterWrapper or the wrapped DataAdapter directly.

Public Methods

public boolean add (Data<Tx, Ty> dataPoint)

public void add (int location, Data<Tx, Ty> dataPoint)

public boolean addAll (int location, Collection<? extends Data<Tx, Ty>> dataPoints)

public boolean contains (Object object)

public boolean containsAll (Collection<?> collection)

public Data<Tx, Ty> get (int location)

public abstract List<Data<Tx, Ty>> getDataPointsForDisplay ()

Implementations of this method should return a list of data points which are to be displayed on the chart. This method is called by the chart framework in response to notifyDataChanged(). It is not normally called by client code, though there is no harm in doing so.

Returns
  • a list of data points which are to be displayed on the chart
