Class LogicalInverter

java.lang.Object

org.apache.parquet.filter2.predicate.LogicalInverter

All Implemented Interfaces:

FilterPredicate.Visitor<FilterPredicate>

public final class LogicalInverter
extends Object
implements FilterPredicate.Visitor<FilterPredicate>

Converts a FilterPredicate to its logical inverse. The returned predicate should be equivalent to not(p), but without the use of a not() operator.

See also LogicalInverseRewriter, which can remove the use of all not() operators without inverting the overall predicate.
