Interface ListModel<E>

Type Parameters:: E - the type of the elements of this model

All Known Subinterfaces:: ComboBoxModel<E>, MutableComboBoxModel<E>

All Known Implementing Classes:: AbstractListModel, BasicDirectoryModel, DefaultComboBoxModel, DefaultListModel, MetalFileChooserUI.DirectoryComboBoxModel, MetalFileChooserUI.FilterComboBoxModel

public interface ListModel<E>

This interface defines the methods components like JList use to get the value of each cell in a list and the length of the list. Logically the model is a vector, indices vary from 0 to ListDataModel.getSize() - 1. Any change to the contents or length of the data model must be reported to all of the ListDataListeners.

Since:: 1.2
