Constructor Detail

ListViewAdapter

public ListViewAdapter()

Creates an empty model.

ListViewAdapter

public ListViewAdapter(java.util.List<T> wrappee)

Creates a list model that wraps the given collection. Changes to the wrapped list must be made via this model in order to be correctly applied to views.

Method Detail

flush

public void flush()

Flush pending list changes to the views. By default, views are informed of modifications to the underlying list at the end of the current event loop, which makes it possible to perform multiple operations synchronously without repeatedly refreshing the views. This method can be called to flush the changes immediately instead of waiting until the end of the current event loop.

getList

public java.util.List<T> getList()

Get the list that backs this model. Changes to the list will be reflected in the model.

Returns:

the list

refresh

public void refresh()

Refresh all of the views listening to this adapter.

setList

public void setList(java.util.List<T> wrappee)

Replaces this model's list.

Parameters:

wrappee - the model's new list
