Class UnambiguousIteratorImpl<T extends AnnotationFS>

java.lang.Object

org.apache.uima.cas.impl.FSIteratorImplBase<T>

org.apache.uima.cas.impl.UnambiguousIteratorImpl<T>

All Implemented Interfaces:

java.util.Iterator<T>, FSIterator<T>

public class UnambiguousIteratorImpl<T extends AnnotationFS>
extends FSIteratorImplBase<T>

Implementation of the unambiguous iterators.

Warning: this implementation creates a copy of the collection, so changes in the underlying collection are not reflected by this iterator.

                       int end,
                       boolean strict)

Method Detail

isValid

public boolean isValid()

Description copied from interface: FSIterator

Check if this iterator is valid.

Returns:

true if the iterator is valid.

get

public T get()
                           throws java.util.NoSuchElementException

Description copied from interface: FSIterator

Get the structure the iterator is pointing at.

Returns:

The structure the iterator is pointing at.

Throws:

java.util.NoSuchElementException - If the iterator is not valid.

moveToNext

public void moveToNext()

Description copied from interface: FSIterator

Advance the iterator. This may invalidate the iterator.

moveToPrevious

public void moveToPrevious()

Description copied from interface: FSIterator

Move the iterator one element back. This may invalidate the iterator.

moveToFirst

public void moveToFirst()

Description copied from interface: FSIterator

Move the iterator to the first element. The iterator will be valid iff the underlying collection is non-empty.

moveToLast

public void moveToLast()

Description copied from interface: FSIterator

Move the iterator to the last element. The iterator will be valid iff the underlying collection is non-empty.

moveTo

public void moveTo(FeatureStructure fs)

Description copied from interface: FSIterator

Move the iterator to the first features structure that is equal to fs. If no such feature structure exists in the underlying collection, set the iterator to the "insertion point" for fs, i.e., to a point where the current feature structure is greater than fs, and the previous one is less than fs.

Parameters:

fs - The feature structure the iterator should be set to.

copy

public FSIterator<T> copy()

Description copied from interface: FSIterator

Copy this iterator.

Returns:

A copy of this iterator, pointing at the same element.
