Enclosing class:

DefaultParameterDescriptorGroup

private static final class DefaultParameterDescriptorGroup.AsList
extends UnmodifiableArrayList<org.opengis.parameter.GeneralParameterDescriptor>

The DefaultParameterDescriptorGroup.descriptors as an unmodifiable list. This class overrides contains(Object) with a faster implementation based on HashSet. This optimizations is helpful for map projection implementations, which test often for a parameter validity.
