Interface StageSpec

All Known Subinterfaces:

StageSpec.PayloadSpec, StageSpec.TransformSpec

All Known Implementing Classes:

StageSpec.BitPackPayload, StageSpec.DeltaStage, StageSpec.GcdStage, StageSpec.OffsetStage

public sealed interface StageSpec
permits StageSpec.TransformSpec, StageSpec.PayloadSpec

Sealed hierarchy capturing pipeline stage specifications.

Each record represents a stage type. References StageId as the source of truth for persisted byte identifiers.

Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static final record	StageSpec.BitPackPayload	Bit-packing payload: packs values using the minimum number of bits.
static final record	StageSpec.DeltaStage	Delta encoding: stores differences between consecutive values.
static final record	StageSpec.GcdStage	GCD factoring: divides all values by their greatest common divisor.
static final record	StageSpec.OffsetStage	Offset removal: subtracts the minimum value from all entries.
static interface	StageSpec.PayloadSpec	Marker for terminal payload stages that serialize values to bytes.
static interface	StageSpec.TransformSpec	Marker for transform stages that can be chained in the pipeline.
