public abstract class ExtendedScopeNodeModel extends NodeModel
NodeModel that widens the scope of some of the methods. It's used internally
by certain system nodes like the subnode internal start/end nodes to have more control. For instance, they allow
the node model implementation to set the entire node inactive.| Modifier | Constructor and Description |

Invokes the abstract #execute() method of this model. In
addition, this method notifies all assigned views of the model about the
changes.executeModel in class NodeModelrawData - An array of PortObject objects holding the data
from the inputs (includes flow variable port).exEnv - The execution environment used for execution of this model.exec - The execution monitor which is passed to the execute method
of this model.DataTable elements, as many as the node has
outputs.Exception - any exception or error that is fired in the derived
model will be just forwarded. It may throw an
CanceledExecutionException if the user pressed cancel during
execution. Even if the derived model doesn't check, the
result will be discarded and the exception thrown.IllegalStateException - If the number of PortObject
objects returned by the derived NodeModel
does not match the number of outputs. Or if any of them is
null.NodeModel.execute(PortObject[],ExecutionContext)
