Interface ContainsFilter

All Superinterfaces:

Filter

All Known Subinterfaces:

ConstPositionFilter, ContainsAllFilter, TwoFiltersPositionFilter

public interface ContainsFilter
extends Filter

The super interface for all filters that match on some kind of "contains" relation. This is used directly by the "CONTAINS ONLY" and "CONTAINS ANY" filters and extended for the "CONTAINS ALL" and the "POSITION" filters.

Example:

• AllowedAgents CONTAINS ONLY (Department = Accounting) matches if *all* allowed agents are working in the accounting department (like a universal quantifier)
• AllowedAgents CONTAINS ANY (Department = Accounting) matches if there is at least one agent who is working in the accounting department (like a existential quantifier)
• AllowedAgents CONTAINS ALL (Department = Accounting) matches if *all* agents working in the accounting department are allowed agents (if the agents in the accounting department are a subset of the allowed agents)

To make the difference between CONTAINS ALL and CONTAINS ONLY a bit more clear, you can also phrase it like that:
CONTAINS ALL tests if the agents in the accounting department are a subset of the allowed agents
CONTAINS ONLY tests if the allowed agents are a subset of agents in the accounting department
