DependentProcedureExecutionNode
public DependentProcedureExecutionNode(int nodeID,
Criteria crit,
java.util.List references,
java.util.List defaults)
getDescriptionProperties
public java.util.Map getDescriptionProperties()
- Description copied from interface:
Describable
- Get a description as a set of properties of primitive types such
as String, Integer, etc.
- Specified by:
getDescriptionProperties
in interface Describable
- Overrides:
getDescriptionProperties
in class PlanExecutionNode
- Returns:
- Map of properties
clone
public java.lang.Object clone()
- Description copied from class:
RelationalNode
- All the implementation of Cloneable interface need to implement clone() method.
The plan is only clonable in the pre-execution stage, not the execution state
(things like program state, result sets, etc). It's only safe to call that method in between query processings,
in other words, it's only safe to call clone() on a plan after nextTuple() returns null,
meaning the plan has finished processing.
