Examples with EvaluationTrackingIterator datawave.query.iterator.profile.EvaluationTrackingIterator used on opensource projects

Example 1 with EvaluationTrackingIterator

use of datawave.query.iterator.profile.EvaluationTrackingIterator in project datawave by NationalSecurityAgency.

the class QueryIterator method createDocumentPipeline.

/**
 * Create the pipeline. It is very important that this pipeline can handle resetting the bottom iterator with a new value. This means that hasNext() needs
 * to call the next iterator. The only state that can be maintained is the next value ready after hasNext() has been called. Once next returns the value,
 * the next hasNext() call must call the next iterator again. So for example Iterators.filter() cannot be used as it uses a google commons AbstractIterator
 * that maintains an iterator state (failed, ready, done); use statelessFilter above instead.
 *
 * @param deepSourceCopy
 * @param documentSpecificSource
 * @return iterator of keys and values
