Package io.deephaven.server.table.ops.filter

Class MakeExpressionsNullSafe

java.lang.Object

io.deephaven.server.table.ops.filter.AbstractNormalizeFilters

io.deephaven.server.table.ops.filter.MakeExpressionsNullSafe

All Implemented Interfaces:

FilterVisitor<io.deephaven.proto.backplane.grpc.Condition>

public class MakeExpressionsNullSafe
extends AbstractNormalizeFilters

Rewrites logical expressions into an actual version that does what would be expected. Right now this is just equalsIgnoreCase and its negation, to support null values. Note that some of the branches here should not be needed (such as reference.equalsIgnoreCase("literal")) as they should be replaced by a MatchFilter instead, but this may not be fully implemented, so we are defensively leaving these cases in place for now.
