Imports

A JoinedIterable is an Iterable that wraps a number of Iterables. This class makes multiple iterables look like one to the caller. When any method from the Iterator interface is called on the Iterator object returned by iterator(), the JoinedIterable will delegate to a single underlying Iterator. The JoinedIterable will invoke the iterator on each Iterable, in sequence, until all Iterators are exhausted.

hasNextback to summary
public boolean hasNext()

Implements java.util.Iterator.hasNext.

Doc from java.util.Iterator.hasNext.

Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

Returns:boolean

true if the iteration has more elements

nextback to summary
public T next()

Implements java.util.Iterator.next.

Doc from java.util.Iterator.next.

Returns the next element in the iteration.

Returns:T

the next element in the iteration

removeback to summary
public void remove()

Overrides default java.util.Iterator.remove.

Doc from java.util.Iterator.remove.

Removes from the underlying collection the last element returned by this iterator (optional operation). This method can be called only once per call to next.

The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method, unless an overriding class has specified a concurrent modification policy.

The behavior of an iterator is unspecified if this method is called after a call to the forEachRemaining method.
