All Implemented Interfaces:

org.apache.accumulo.core.iterators.OptionDescriber, org.apache.accumulo.core.iterators.SortedKeyValueIterator<org.apache.accumulo.core.data.Key,org.apache.accumulo.core.data.Value>, org.apache.accumulo.core.iterators.YieldingKeyValueIterator<org.apache.accumulo.core.data.Key,org.apache.accumulo.core.data.Value>

Direct Known Subclasses:

ElementPostAggregationFilter, ElementPreAggregationFilter, ValidatorFilter

public abstract class AbstractElementFilter
extends org.apache.accumulo.core.iterators.Filter

The AbstractElementFilter will filter out Elements based on the filtering instructions given in the Schema or View that is passed to this iterator.
