Method Detail

getValueProperty

public org.eclipse.core.databinding.property.value.IValueProperty getValueProperty()
Returns the IValueProperty for this cell editor which is used by the table to create an IObservableValue.

Specified by:
getValueProperty in interface ECPCellEditor
Returns:
the IValueProperty for this cell editor
See Also:
ECPCellEditor.getValueProperty()

instantiate

public void instantiate(org.eclipse.emf.ecore.EStructuralFeature eStructuralFeature,
                        ViewModelContext viewModelContext)
Instantiates this cell editor. This allows the cell editor to use ViewModelServices.

Specified by:
instantiate in interface ECPCellEditor
Parameters:
eStructuralFeature - the EStructuralFeature displayed in this cell editor
viewModelContext - the ViewModelContext used for the current view
See Also:
