Class DataModelImpl

java.lang.Object

ucar.unidata.view.sounding.DataModelImpl

public class DataModelImpl
extends java.lang.Object

Provides support for adapting a JList of sounding observations to the API-s of the sounding and wind data models. The conceptual model that this class presents is that of a set of soundings -- a subset of which are the SELECTED SOUNDINGS -- and of which at most one sounding is the SELECTED SOUNDING. The soundings that constitute the set may change -- as may the selected soundings and the selected sounding. Modifications to the soundings by users of this class will appear to actually modify the soundings in the set.

Constructor Detail

DataModelImpl

public DataModelImpl(javax.swing.JList jList)

Constructs from a JList. The JList's data model and selection model must be in their final form. The SELECTED_INDEX property of this instance will be bound to the "selectedIndex" property of the JList and PropertyChangeEvent-s will be propagated.

Parameters:

jList - The underlying JList whose mutable data model contains the sounding data and whose list selection model determines the selected soundings and selected sounding.

Method Detail

Returns:

The number of soundings.

isSelectedIndex

public boolean isSelectedIndex(int index)

Indicates if the given sounding is a member of the selected soundings.

Parameters:

index - The index of the sounding.

Returns:

true if and only if the given sounding is a member of the selected soundings.

getSelectedIndex

public int getSelectedIndex()

Returns the index of the selected sounding.

Returns:

The index of the selected thing or -1 if nothing is selected.
