Interface SelectorVisitor<R>

Type Parameters:

R -

All Known Implementing Classes:

CompatibleSelectVisitor, FilterSelectVisitor, MatchSelectVisitor, ResolveCheckVisitor.CaseCompatibleVisitor

public interface SelectorVisitor<R>

Visitor class for RecordSelector Bottom level classes that implement RecordSelector are visited directly. The methods on the collection classes will normally be implemented by recursing down to the SelectClause This interface assumes that RecordSelectors are made from And/Or combinations of SelectClause objects. If the data model for RecordSelectors is extended this interface will also need to be extended but this should become obvious when implementing the visit method of the extended RecordSelector
