Constructor Detail

LogicalWindow

public LogicalWindow(org.apache.calcite.plan.RelOptCluster cluster,
                     org.apache.calcite.plan.RelTraitSet traitSet,
                     List<org.apache.calcite.rel.hint.RelHint> hints,
                     org.apache.calcite.rel.RelNode input,
                     List<org.apache.calcite.rex.RexLiteral> constants,

                     List<Window.Group> groups)

Creates a LogicalWindow.

Use create(org.apache.calcite.plan.RelTraitSet, org.apache.calcite.rel.RelNode, java.util.List<org.apache.calcite.rex.RexLiteral>, org.apache.calcite.rel.type.RelDataType, java.util.List<org.apache.calcite.rel.core.Window.Group>) unless you know what you're doing.

Parameters:

cluster - Cluster

traitSet - Trait set

hints - hints for this node

input - Input relational expression

constants - List of constants that are additional inputs

rowType - Output row type

groups - Window groups

LogicalWindow
