Interface AscendingLongIterator

public interface AscendingLongIterator

Iterates over a set of non-negative long values in ascending order.

Field Summary

Fields

Modifier and Type	Field and Description
static AscendingLongIterator	EMPTY Denotes an empty ordered long iterator.
static long	END Identifies an iterator end.

Method Summary

Modifier and Type	Method and Description
long	advance() Advances this iterator to the next index.
long	advanceAtLeastTo(long member) Advances this iterator to the given member; or, if the member is not present in this iterator, to an index immediately following it and present in the iterator or END if no such index exists.
long	getIndex() Returns a value at which this iterator is positioned currently or END if this iterator has reached its end.

Field Detail

END

static final long END

Identifies an iterator end.

Don't change this value, iteration logic relies on it being exactly -1L.

Constant Field Values

EMPTY

static final AscendingLongIterator EMPTY

Denotes an empty ordered long iterator.

Method Detail

getIndex

long getIndex()

Returns a value at which this iterator is positioned currently or END if this iterator has reached its end.

Just after the creation, iterators are positioned at their first value.

"Index" is used instead of "value" since SparseArray.Iterator interface extends this interface with SparseArray.Iterator.getValue() method.

advance

long advance()

Advances this iterator to the next index.

Returns:

an index at which this iterator was positioned before the advancement or END if this iterator already was at its end. Once the end is reached, return value is always END on any subsequent advancement attempts.

advanceAtLeastTo

long advanceAtLeastTo(long member)

Advances this iterator to the given member; or, if the member is not present in this iterator, to an index immediately following it and present in the iterator or END if no such index exists.

Parameters:

member - the member to advance at least to.

Returns:

an index at which this iterator was advanced to or END if this iterator reached its end. Once the end is reached, return value is always END on any subsequent advancement attempts.
