Class NumericDecoder

java.lang.Object

org.elasticsearch.index.codec.tsdb.pipeline.numeric.NumericDecoder

public final class NumericDecoder
extends Object

Read-path coordinator for pipeline-based numeric decoding. This is the entry point used by the doc values producer to decode numeric fields. It owns a NumericDecodePipeline and produces NumericBlockDecoder instances for per-block decoding.

Instances are immutable and thread-safe. Per-field mutable state lives in NumericBlockDecoder, which callers obtain via newBlockDecoder().

Created via fromDescriptor(org.elasticsearch.index.codec.tsdb.pipeline.PipelineDescriptor) or via NumericCodecFactory.createDecoder(org.elasticsearch.index.codec.tsdb.pipeline.PipelineDescriptor).
