Enum Class OrcFile.WriterVersion

java.lang.Object
java.lang.Enum<OrcFile.WriterVersion>
org.apache.orc.OrcFile.WriterVersion
All Implemented Interfaces:
Serializable, Comparable<OrcFile.WriterVersion>, Constable
Enclosing class:
OrcFile
public static enum OrcFile.WriterVersion extends Enum<OrcFile.WriterVersion>
Records the version of the writer in terms of which bugs have been fixed. When you fix bugs in the writer (or make substantial changes) that don't change the file format, add a new version here instead of Version. The ids are assigned sequentially from 6 per a WriterImplementation so that readers that predate ORC-202 treat the other writers correctly.
