Class AbstractDoubleCollection

public abstract class AbstractDoubleCollection extends Object implements DoubleCollection

Abstract base class for DoubleCollections.

Read-only subclasses must override AbstractDoubleCollection and AbstractDoubleCollection. Mutable subclasses should also override AbstractDoubleCollection and DoubleIterator.remove. All other methods have at least some base implementation derived from these. Subclasses may choose to override these methods to provide a more efficient implementation.
