ValidatableTransformer (Cytoscape Swing App API (swing-app-api) 3.8.0 API)

All Superinterfaces:

Transformer<C,E>
```
public interface ValidatableTransformer<C,E>
extends Transformer<C,E>
```
A marker interface that can be added to any Transformer to indicate that the transformer may be invalid in certain contexts. For example a ColumnFilter is invalid when the current network does not contain the column referenced by the filter. Validation runs whenever the context changes (for example when the current network changes) or when the TransformerListeners for this transformer are notified.

Transformer.addListener(TransformerListener)
