Method Detail

map

default <U> CloseableIterator<U> map(java.util.function.Function<T,U> mapper)

filter

default CloseableIterator<T> filter(java.util.function.Function<T,Boolean> mapper)

combine

default CloseableIterator<T> combine(CloseableIterator<T> other)

Combine the current iterator with another iterator. The resulting iterator will return all elements from the current iterator followed by all elements from the other iterator.

Parameters:

other - the other iterator to combine with

Returns:

a new iterator that combines the current iterator with the other iterator
