Constructor Detail

Predicate

public Predicate(List<RexExpression> operands,
                 DataSchema dataSchema,
                 IntPredicate comparisonResultPredicate)

Predicate constructor also resolve data type, since we don't have an exhausted list of filter function signatures. we rely on type casting.

• if both RHS and LHS has null data type, exception occurs.
• if either side is null or OBJECT, we best-effort cast data into the other side's data type.
• if either side supertype of the other, we use the super type.
• if we can't resolve a common data type, exception occurs.
