Package io.github.zhh2001.jp4.pipeline

Class RegisterInfo

java.lang.Object
io.github.zhh2001.jp4.pipeline.RegisterInfo
public final class RegisterInfo extends Object
Read-only metadata for one P4 register array, derived from P4Info. Construction is internal to P4Info.fromBytes(byte[]) and friends; users obtain instances through P4Info.register(String).

The register's per-cell P4DataTypeSpec is intentionally not exposed on this value type; v1.4 surfaces register cell data as raw Bytes on the read path, matching the convention DigestEvent uses for P4Data. Typed register payloads are a future v1.x topic.

Instances are constructed once during P4Info parsing and are immutable thereafter; safe to share across threads.

Since:
1.4.0
