Package org.apache.druid.segment.data

Class SliceIndexedInts

java.lang.Object

org.apache.druid.segment.data.SliceIndexedInts

All Implemented Interfaces:

HotLoopCallee, IndexedInts

public final class SliceIndexedInts
extends Object
implements IndexedInts

Reusable IndexedInts, that could represent a sub-sequence ("slice") in a larger IndexedInts object. Used in CompressedVSizeColumnarMultiIntsSupplier implementation. Unsafe for concurrent use from multiple threads.

inspectRuntimeShape

public void inspectRuntimeShape(RuntimeShapeInspector inspector)

Description copied from interface: HotLoopCallee

Implementations of this method should call inspector.visit() with all fields of this class, which meet two conditions: 1. They are used in methods of this class, annotated with CalledFromHotLoop 2. They are either: a. Nullable objects b. Instances of HotLoopCallee c. Objects, which don't always have a specific class in runtime. For example, a field of type Set could be HashSet or TreeSet in runtime, depending on how this instance (the instance on which inspectRuntimeShape() is called) is configured. d. ByteBuffer or similar objects, where byte order matters e. boolean flags, affecting branch taking f. Arrays of objects, meeting any of conditions a-e.
