ScopeStartNode

Type Parameters:

T - parameterized on the particular scope context implementation

All Known Subinterfaces:

All Known Implementing Classes:

BWElimLoopStartNodeModel, ColumnListLoopStartNodeModel, ColumnListLoopStartNodeModel, GenericTryNodeModel, GroupLoopStartNodeModel, LoopStartChunkNodeModel, LoopStartCountNodeModel, LoopStartGenericNodeModel, LoopStartIntervalNodeModel, LoopStartVariableNodeModel, RecursiveLoopStart2NodeModel, RecursiveLoopStartNodeModel, XValidatePartitionModel
```
public interface ScopeStartNode<T extends FlowScopeContext>
```
Interface implemented by NodeModel classes to define a the start of a new scope. The framework will take care of the details, in this case making sure variables put onto the stack inside the scope are removed when leaving it again. Derivatives of this interface, such as LoopStartNode add functionality on top of the scope.
