copy
public Bindables.BindableProject copy(RelTraitSet traitSet, RelNode input, java.util.List<RexNode> projects, RelDataType rowType)
Description copied from class:Project
Copies a project.- Specified by:
copy
in classProject
- Parameters:
traitSet
- Traitsinput
- Inputprojects
- Project expressionsrowType
- Output row type- Returns:
- New
Project
if any parameter differs from the value of thisProject
, or justthis
if all the parameters are the same - See Also:
Project.copy(RelTraitSet, List)
-
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:
