Class CompoundIterator<T>

java.lang.Object

org.eclipse.equinox.internal.p2.metadata.expression.CompoundIterator<T>

All Implemented Interfaces:

java.util.Iterator<T>

public class CompoundIterator<T>
extends java.lang.Object
implements java.util.Iterator<T>

A CompoundIterator will assume that its contained iterator that will produce elements that in turn can be represented as iterators. The elements of those iterators will be returned in sequence, thus removing one iterator dimension. Elements of the contained iterator that are not iterators will be coerced into iterators using RepeatableIterator.create(Object).

CompoundIterator

public CompoundIterator(java.util.Iterator<? extends java.lang.Object> iterator)

Creates a compound iterator that will iterated over the elements of the provided iterator. Each element will be coerced into an iterator and its elements in turn are returned in succession by the compound iterator.

Parameters:

iterator -
