public final class IncrementalFileMergerState
extends java.lang.Object
implements java.io.Serializable
IncrementalFileMergerState().
States are serializable so they can be persisted across invocations of merge operations. They
are also immutable. The incremental merger will build new instances using Builder.
Users of the incremental merger will generally not need to use anything from the state,
except providing it to invocations of
IncrementalFileMerger#merge(List, IncrementalFileMergerOutput,
IncrementalFileMergerState). Therefore, this class is mostly opaque.
