Modifier and Type	Method and Description
default int	back(int amount) Reverses the Given amount of elements if possible.
boolean	hasPrevious() Returns true if the Iterator has a Previous element
default java.lang.Long	previous() Deprecated. Please use the corresponding type-specific function instead.
long	previousLong() Returns the Previous element of the iterator.

Method Detail

hasPrevious

boolean hasPrevious()

Returns true if the Iterator has a Previous element

Specified by:

hasPrevious in interface ObjectBidirectionalIterator<java.lang.Long>

Returns:

true if the Iterator has a Previous element

previousLong

long previousLong()

Returns the Previous element of the iterator.

Returns:

the Previous element of the iterator.

Throws:

java.util.NoSuchElementException - if the iteration has no more elements

previous

@Deprecated
default java.lang.Long previous()

Deprecated. Please use the corresponding type-specific function instead.

Returns the Previous element of the iterator.

This default implementation delegates to the corresponding type-specific function.

Specified by:

previous in interface ObjectBidirectionalIterator<java.lang.Long>

Returns:

the Previous element of the iterator.

skip

default int skip(int amount)

Skips the Given amount of elements if possible. A Optimization function to skip elements faster if the implementation allows it.

Specified by:

skip in interface LongIterator

Specified by:

skip in interface ObjectIterator<java.lang.Long>

Parameters:

amount - the amount of elements that should be skipped

Returns:

the amount of elements that were skipped

back

default int back(int amount)

Reverses the Given amount of elements if possible. A Optimization function to reverse elements faster if the implementation allows it.

Specified by:

back in interface ObjectBidirectionalIterator<java.lang.Long>

Parameters:

amount - the amount of elements that should be reversed

Returns:

the amount of elements that were reversed
