Class GroupedSet<GroupingValueType,GroupedKeyType,WholeKeyType>

java.lang.Object

tools.refinery.interpreter.rete.aggregation.GroupedSet<GroupingValueType,GroupedKeyType,WholeKeyType>

All Implemented Interfaces:

Iterable<WholeKeyType>, Collection<WholeKeyType>, Set<WholeKeyType>

public class GroupedSet<GroupingValueType,GroupedKeyType,WholeKeyType>
extends Object
implements Set<WholeKeyType>

An optimized Set implementation where each contained value is produced by combining together a grouping value and some other (key) object. The way of combining together these two values is specified by the closure passed to the constructor. Only a select few Set operations are supported. This collection is unmodifiable.

Since:
