Class ContextAwareNodeFactory<T extends NodeModel>

java.lang.Object
  org.knime.core.node.NodeFactory<T>
      org.knime.core.node.ContextAwareNodeFactory<T>

Type Parameters:

T - any subclass of NodeModel

Direct Known Subclasses:

CSVReaderNodeFactory, FileReaderNodeFactory, PMMLReaderNodeFactory, ReadTableNodeFactory

public abstract class ContextAwareNodeFactory<T extends NodeModel>
extends NodeFactory<T>

This extension of NodeFactory is used in order to create a new node in a certain context. Implementors who wish that their nodes can be used in a context (e.g. when a file is dropped onto the workflow editor) should extend this class instead of NodeFactory and register the factory in the plugin.xml (in addition to the normal registration).
