java.lang.Object
  org.picocontainer.parameters.CollectionComponentParameter
      org.picocontainer.gems.constraints.AbstractConstraint
          org.picocontainer.gems.constraints.Or

All Implemented Interfaces:

Serializable, Constraint, org.picocontainer.Parameter

public final class Or
extends AbstractConstraint

Aggregates multiple constraints together using boolean OR logic. Constraints are short-circuited as in java.
