Constructor Detail

TableDataContentProvider

public TableDataContentProvider()
Method Detail

dispose

public void dispose()
Specified by:
dispose in interface org.eclipse.jface.viewers.IContentProvider

inputChanged

public void inputChanged(org.eclipse.jface.viewers.Viewer viewer,
                         java.lang.Object oldInput,
                         java.lang.Object newInput)
Notifies this content provider that the given viewer's input has been switched to a different element.

A typical use for this method is registering the content provider as a listener to changes on the new input (using model-specific means), and deregistering the viewer from the old input. In response to these change notifications, the content provider should update the viewer (see the add, remove, update and refresh methods on the viewers).

The viewer should not be updated during this call, as it might be in the process of being disposed.

Specified by:
inputChanged in interface org.eclipse.jface.viewers.IContentProvider
Parameters:
viewer - AccessibleTableViewer
oldInput - the old input element (ITableData), or null if the viewer did not previously have an input.
newInput - the new input element (ITableData), or null if the viewer does not have an input

getElements

public java.lang.Object[] getElements(java.lang.Object inputElement)
Returns the elements to display in the viewer when its input is set to the given element. These elements can be presented as rows in a table. The result is not modified by the viewer.

Specified by:
getElements in interface org.eclipse.jface.viewers.IStructuredContentProvider
Parameters:
inputElement - the input element (ITableData)
Returns:
the array of elements (IRowData) to display in the viewer
