Returns:

!hasNext()

size

int size()

The number of members of the sequence. If this is unknown, return UNKNOWN_ELEMENTS_COUNT.

Returns:

The estimated size of the sequence, or UNKNOWN_SIZE, if it is unknown

hasNext

boolean hasNext()

Whether this sequence has more elements.

Specified by:

hasNext in interface Iterator<T>

Iterator.hasNext()

next

T next()

The next element of the sequence. At any moment, if size() is not equal to UNKNOWN_SIZE, this means that this method may be invoked approximately up to size() times.

Specified by:

next in interface Iterator<T>

remove
