Class AbstractStepsLikeGapped<Sub,Semi extends Sub>

java.lang.Object

scala.compat.java8.converterImpl.AbstractStepsLikeGapped<Sub,Semi>

All Implemented Interfaces:

EfficientSubstep

Direct Known Subclasses:

StepsDoubleLikeGapped, StepsIntLikeGapped, StepsLikeGapped, StepsLongLikeGapped

public abstract class AbstractStepsLikeGapped<Sub,Semi extends Sub>
extends java.lang.Object
implements EfficientSubstep

Abstracts all the generic operations of stepping over a backing array for some collection where the elements are stored generically and some may be missing. Subclasses should set currentEntry to null when it is used as a signal to look for more entries in the array. (This also allows a subclass to traverse a sublist by updating currentEntry.)
