copy
public EnumerableBindable copy(RelTraitSet traitSet, java.util.List<RelNode> inputs)
Description copied from interface:RelNode
Creates a copy of this relational expression, perhaps changing traits and inputs.Sub-classes with other important attributes are encouraged to create variants of this method with more parameters.
- Specified by:
copy
in interfaceRelNode
- Overrides:
copy
in classAbstractRelNode
- Parameters:
traitSet
- Trait setinputs
- Inputs- Returns:
- Copy of this relational expression, substituting traits and inputs
-
getElementType
public java.lang.Class<java.lang.Object[]> getElementType()
Description copied from interface:Typed
Gets the type of the element(s) that are returned in this collection.- Specified by:
getElementType
in interfaceArrayBindable
- Specified by:
getElementType
in interfaceTyped
-
bind
public Enumerable<java.lang.Object[]> bind(DataContext dataContext)
Description copied from interface:Bindable
Executes this statement and returns an enumerable which will yield rows. Theenvironment
parameter provides the values in the root of the environment (usually schemas).
-
implement
public Node implement(InterpretableRel.InterpreterImplementor implementor)
Description copied from interface:InterpretableRel
Creates an interpreter node to implement this relational expression.- Specified by:
