Constructor Detail

ValuesRel

public ValuesRel(RelOptCluster cluster,
                 RelDataType rowType,
                 List<List<RexLiteral>> tuples)

Creates a new ValuesRel. Note that tuples passed in become owned by this rel (without a deep copy), so caller must not modify them after this call, otherwise bad things will happen.

Parameters:

cluster - .

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
