Examples of MultiReader

org.apache.accumulo.server.tabletserver.log.MultiReader
Provide simple Map.Reader methods over multiple Maps. Presently only supports next() and seek() and works on all the Map directories within a directory. The primary purpose of this class is to merge the results of multiple Reduce jobs that result in Map output files.

org.apache.lucene.index.MultiReader
An IndexReader which reads multiple indexes, appending their content.
org.codehaus.commons.io.MultiReader
Similar to {@link FilterReader}, but when the first delegate is at end-of-input, it continues with reading from the next delegate.
This {@link Reader} does not support MARK.
