io.druid.segment.data

Class Offset

java.lang.Object

io.druid.segment.data.Offset

All Implemented Interfaces:

HotLoopCallee, ReadableOffset, Cloneable

Direct Known Subclasses:

ArrayBasedOffset, BitmapOffset, FilteredOffset, IntersectingOffset, QueryableIndexStorageAdapter.NoFilterOffset, QueryableIndexStorageAdapter.TimestampCheckingOffset, UnioningOffset

@SubclassesMustBePublic
public abstract class Offset
extends Object
implements ReadableOffset, Cloneable

The "mutable" version of a ReadableOffset. Introduces "increment()" and "withinBounds()" methods, which are very similar to "next()" and "hasNext()" on the Iterator interface except increment() does not return a value. Annotated with SubclassesMustBePublic because Offset occurrences are replaced with a subclass in Historical1SimpleDoubleAggPooledTopNScannerPrototype and HistoricalSingleValueDimSelector1SimpleDoubleAggPooledTopNScannerPrototype during specialization, and specialized version of those prototypes must be able to any subclass of Offset.
