Interface Match

All Known Implementing Classes:
Match.Exact, Match.Lpm, Match.Optional, Match.Range, Match.Ternary
public sealed interface Match permits Match.Exact, Match.Lpm, Match.Ternary, Match.Range, Match.Optional
One value in a TableEntry match key. Sealed; subtypes correspond to the P4Runtime FieldMatch oneof variants. Use switch on a returned Match for compile-time exhaustive handling.

All five variants are immutable records, safe to share across threads. The byte[]-bearing variants (Match.Exact, Match.Lpm, Match.Ternary, Match.Range, Match.Optional) wrap their Bytes fields, which defensively copy on construction; mutating an input array does not affect a constructed Match value.
