Examples of org.apache.hadoop.hbase.filter.FilterList

org.apache.hadoop.hbase.filter.FilterList
Implementation of {@link Filter} that represents an ordered List of Filterswhich will be evaluated with a specified boolean operator {@link Operator#MUST_PASS_ALL}(!AND) or {@link Operator#MUST_PASS_ONE} (!OR).Since you can use Filter Lists as children of Filter Lists, you can create a hierarchy of filters to be evaluated. Defaults to {@link Operator#MUST_PASS_ALL}.
TODO: Fix creation of Configuration on serialization and deserialization.
