java.lang.Object

org.openl.rules.datatype.binding.DatatypeNodeLevelComparator

All Implemented Interfaces:

Comparator<TableSyntaxNode>

public class DatatypeNodeLevelComparator
extends Object
implements Comparator<TableSyntaxNode>

Compares datatype TableSyntaxNodes. This comparing is needed to build queue of datatypes for binding phase(We have to bind parent datatype before all datatypes that inherits it)
