public interface LongIterator
extends java.util.PrimitiveIterator.OfLong

Method Details
-
nextLong
long nextLong()Returns the next element as a primitive type.- Specified by:
nextLong
in interfacejava.util.PrimitiveIterator.OfLong
- Returns:
- the next element in the iteration.
- See Also:
Iterator.next()
-
next
@Deprecated default java.lang.Long next()Deprecated.Please use the corresponding type-specific method instead.- Specified by:
next
in interfacejava.util.Iterator<java.lang.Long>
- Specified by:
next
in interfacejava.util.PrimitiveIterator.OfLong
-
forEachRemaining
Performs the given action for each remaining element until all elements have been processed or the action throws an exception.WARNING: Overriding this method is almost always a mistake, as this overload only exists to disambiguate. Instead, override the
forEachRemaining()
overload that uses the JDK's primitive consumer type (e.g.IntConsumer
).If Java supported final default methods, this would be one, but sadly it does not.
If you checked and are overriding the version with
java.util.function.XConsumer
, and still see this warning, then your IDE is incorrectly conflating this method with the proper method to override, and you can safely ignore this message.- Parameters:
action
- the action to be performed for each element.- Since:
- 8.5.0
- See Also:
Iterator.forEachRemaining(java.util.function.Consumer)
-
forEachRemaining
@Deprecated default void forEachRemaining(java.util.function.Consumer<? super java.lang.Long> action)Deprecated.Please use the corresponding type-specific method instead.- Specified by:
forEachRemaining
in interfacejava.util.Iterator<java.lang.Long>
- Specified by:
forEachRemaining
in interfacejava.util.PrimitiveIterator.OfLong
-
skip
default int skip(int n)Skips the given number of elements.The effect of this call is exactly the same as that of calling
next()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.
- See Also:
Iterator.next()
