Examples of opennlp.uima.util.AnnotationComboIterator

opennlp.uima.util.AnnotationComboIterator
with CAS, upper and lower type. AnnotationComboIterator it = new AnnotationComboIterator(cas, sentenceType, tokenType); // Iterate over sentences for (AnnotationIteratorPair aiPair : it) { // Obtain sentence annotation AnnotationFS sentence = aiPair.getAnnotation(); // Do something with sentence... // Iterate over tokens for (AnnotationFS token : aiPair.getSubIterator()) { // Do something with tokens... } } The combo iterator returns in its next() method a pair of an annotation of the upper type (e.g., sentence), and an iterator over annotations of the lower type (e.g., tokens). Note that both the upper and lower iterator also implement the Iterable interface and can be use directly in for-loops.
Note that only this usage is safe. To keep the implementation efficient, the combo iterator keeps two iterators internally that it increments in lock-step. Do not attempt, for example, to collect more than one of the subiterators (token iterator in our example). Do not use this class if your intended usage does not fall into this pattern.
