# FilterStreamByChunk

The FilterStreamByChunk program filters an input stream to an output stream using the Java API method `doFilterChunk()`. The method filters an input source and returns one chunk of output data. The program calls the method repeatedly until the entire output buffer is processed.

NOTE: In KeyView version 12.9 and later, Micro Focus recommends that you implement a `com.verity.api.SeekableInputStream`. See Input/Output Operations.
