public class Set

extends PatternCollection

This is an unordered list of patterns. The agent must traverse all these patterns, but the order of traversal is immaterial, or is determined dynamically by the user-defined choosePattern method. Hence, This pattern also makes the plan more robust, since it can order paths based on host availability.
