Examples of org.eclipse.jface.viewers.ICellModifier

org.eclipse.jface.viewers.ICellModifier
A cell modifier is used to access the data model from a cell editor in an abstract way. It offers methods to:
- to check if a a model element's property can be edited or not
- retrieve a value a model element's property
- to store a cell editor's value back into the model element's property
This interface should be implemented by classes that wish to act as cell modifiers.
