Class Summary |
| CompilationMessageCollector |
This class is used for collecting all messages (error + warning) in
compilation process. |
| CompilationMessageCollector.Message |
|
| DependencyOrderWalker<O extends Operator,P extends OperatorPlan<O>> |
DependencyOrderWalker traverses the graph in such a way that no node is visited
before all the nodes it depends on have been visited. |
| DepthFirstWalker<O extends Operator,P extends OperatorPlan<O>> |
DepthFirstWalker traverses a plan in a depth first manner. |
| DotPlanDumper<E extends Operator,P extends OperatorPlan<E>,N extends Operator,S extends OperatorPlan<N>> |
This class puts everything that is needed to dump a plan in a
format readable by graphviz's dot algorithm. |
| MapKeysInfo |
|
| NodeIdGenerator |
|
| Operator<V extends PlanVisitor> |
Base class for all types of operators. |
| OperatorKey |
|
| OperatorPlan<E extends Operator> |
A generic graphing class for use by LogicalPlan, PhysicalPlan, etc. |
| OperatorPlan.IndexHelper<E> |
|
| PlanDumper<E extends Operator,P extends OperatorPlan<E>,S extends OperatorPlan<? extends Operator>> |
This class dumps a nested plan to a print stream. |
| PlanVisitor<O extends Operator,P extends OperatorPlan<O>> |
A visitor mechanism for navigating and operating on a plan of
Operators. |
| PlanWalker<O extends Operator,P extends OperatorPlan<O>> |
PlanWalker encapsulates the logic to traverse a plan. |
| ProjectionMap |
A struct detailing how a projection is altered by an operator. |
| ProjectionMap.Column |
A wrapper for projection map columns to contain the input number, input
column. |
| RequiredFields |
A struct detailing how a projection is altered by an operator. |
| ReverseDependencyOrderWalker<O extends Operator,P extends OperatorPlan<O>> |
ReverseDependencyOrderWalker traverses the graph in such a way that no node is visited
before all the nodes that are its successors on have been visited. |
