Constructor Detail

LogicalValues

public LogicalValues(org.apache.calcite.plan.RelOptCluster cluster,
                     org.apache.calcite.plan.RelTraitSet traitSet,
                     List<org.apache.calcite.rel.hint.RelHint> hints,
                     org.apache.calcite.rel.type.RelDataType rowType,
                     com.google.common.collect.ImmutableList<com.google.common.collect.ImmutableList<org.apache.calcite.rex.RexLiteral>> tuples)

Creates a LogicalValues.

Use create(org.apache.calcite.plan.RelOptCluster, org.apache.calcite.rel.type.RelDataType, com.google.common.collect.ImmutableList<com.google.common.collect.ImmutableList<org.apache.calcite.rex.RexLiteral>>) unless you know what you're doing.

Parameters:

cluster - Cluster that this relational expression belongs to

hints - Hints for this node

rowType - Row type for tuples produced by this rel

tuples - 2-dimensional array of tuple values to be produced; outer list contains tuples; each inner list is one tuple; all tuples must be of same length, conforming to rowType

LogicalValues

public LogicalValues(org.apache.calcite.plan.RelOptCluster cluster,
                     org.apache.calcite.plan.RelTraitSet traitSet,
                     org.apache.calcite.rel.type.RelDataType rowType,
                     com.google.common.collect.ImmutableList<com.google.common.collect.ImmutableList<org.apache.calcite.rex.RexLiteral>> tuples)

Creates a LogicalValues.

Use create(org.apache.calcite.plan.RelOptCluster, org.apache.calcite.rel.type.RelDataType, com.google.common.collect.ImmutableList<com.google.common.collect.ImmutableList<org.apache.calcite.rex.RexLiteral>>) unless you know what you're doing.

Parameters:

cluster - Cluster that this relational expression belongs to

rowType - Row type for tuples produced by this rel

tuples - 2-dimensional array of tuple values to be produced; outer list contains tuples; each inner list is one tuple; all tuples must be of same length, conforming to rowType
