AlwaysFalse()

Result< std::shared_ptr< Expression > > iceberg::ProjectionVisitor::AlwaysFalse ( )

inlineoverridevirtual

Visit a False expression (always evaluates to false).

Implements iceberg::ExpressionVisitor< std::shared_ptr< Expression > >.

AlwaysTrue()

Result< std::shared_ptr< Expression > > iceberg::ProjectionVisitor::AlwaysTrue ( )

inlineoverridevirtual

Visit a True expression (always evaluates to true).

Implements iceberg::ExpressionVisitor< std::shared_ptr< Expression > >.

Predicate() [1/2]

Result< std::shared_ptr< Expression > > iceberg::ProjectionVisitor::Predicate ( const std::shared_ptr< BoundPredicate > &  pred )

inlineoverridevirtual
