next

public Sample<V> next()
               throws NoSuchElementException

Description copied from interface: TimeIterator

Move forward the iterator and return the next value.

Specified by:

next in interface TimeIterator<V>

Returns:

The next sample

Throws:

NoSuchElementException - If there is no next element

peekNext

public Sample<V> peekNext()
                   throws NoSuchElementException

Description copied from interface: TimeIterator

Peek the next element without moving forward the iterator.

Specified by:

peekNext in interface TimeIterator<V>

Returns:

The next sample

Throws:

NoSuchElementException - If there is no next element

hasNext

public boolean hasNext()

Description copied from interface: TimeIterator

Test if there is a next element.

Specified by:

hasNext in interface TimeIterator<V>

Returns:

True iff there is a next element

peekUpscaleNext

public Sample<V> peekUpscaleNext(Interval interval)

Description copied from interface: UpscalableIterator

Retrieve a sample which contains the upscaled value, relative to the given interval, for the next value. As this operation peeks the next value, the iterator is not moved forward.

Specified by:

peekUpscaleNext in interface UpscalableIterator<V>

Parameters:

interval - The interval to upscaler the value with

Returns:

The upscaled next
