Class RangeSet.SubIter

java.lang.Object

RangeSet<E>.org.apache.sis.util.collection.RangeSet.Iter

org.apache.sis.util.collection.RangeSet.SubIter

All Implemented Interfaces:

Iterator<Range<E>>

Enclosing class:

RangeSet<E extends Comparable<? super E>>

private final class RangeSet.SubIter
extends RangeSet<E>.Iter

The iterator returned by RangeSet.SubSet.iterator(). This iterator is similar to the one returned by RangeSet.iterator(), except that:

• The iteration is restricted to a sub-region of the RangeSet.array.
• The first and last ranges returned by the iterator are intercepted with the range of the subset (other ranges should not need to be intercepted).
• The range removed by remove() is intercepted with the range of the subset.

Field Details

subRange

private final Range<E extends Comparable<? super E>> subRange

A copy of the RangeSet.SubSet.subRange field value at the time of iterator creation.

lower

private final int lower

Index of the first element in the RangeSet.array where to iterate.

Constructor Details

SubIter

SubIter(Range<E> subRange,
 int lower,
 int upper)

Creates a new iterator for the given portion of the RangeSet.array.

Method Details

isFirstOrLast

private boolean isFirstOrLast()

Returns true if the iterator position is at the first or at the last range. This method is accurate only when invoked after super.next().

next

public Range<E> next()

Returns the next element in the iteration.

Specified by:

next in interface Iterator<Range<E extends Comparable<? super E>>>

Overrides:

next in class RangeSet<E extends Comparable<? super E>>.Iter

remove

public void remove()

Removes from the underlying collection the last element returned by the iterator.

Specified by:

remove in interface Iterator<Range<E extends Comparable<? super E>>>

Overrides:

remove in class RangeSet<E extends Comparable<? super E>>.Iter
