Class JCoReFSListIterator<T extends org.apache.uima.cas.FeatureStructure>

java.lang.Object

de.julielab.jcore.utility.JCoReFSListIterator<T>

All Implemented Interfaces:

Iterator<T>, org.apache.uima.cas.FSIterator<T>

public class JCoReFSListIterator<T extends org.apache.uima.cas.FeatureStructure>
extends Object
implements org.apache.uima.cas.FSIterator<T>

An iterator that takes a list of FeatureStructures and returns or navigates its elements exactly in the order the list defines. Actually, the iterator operates on the exact list, so changes are write-through. External changes to the list while iterating may lead to undefined behavior of the iterator.
Since no natural order of the list elements is assumed, the moveTo(FeatureStructure) method is currently not implemented since it couldn't behave as defined in the contract of FSIterator.
