public interface LongIterator
extends java.util.PrimitiveIterator.OfLong

Method Detail

nextLong

long nextLong()

Returns the next element as a primitive type.

Specified by:

nextLong in interface java.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 interface java.util.Iterator<java.lang.Long>

Specified by:

next in interface java.util.PrimitiveIterator.OfLong

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 interface java.util.Iterator<java.lang.Long>

Specified by:

forEachRemaining in interface java.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() for n times (possibly stopping if Iterator.hasNext() becomes false).

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

Iterator.next()
