Class DefaultValueCodec

java.lang.Object

org.j7m.middleware.codec.defaultcodec.DefaultValueCodec

All Implemented Interfaces:

org.j7m.middleware.codec.api.ValueCodec

public final class DefaultValueCodec
extends Object
implements org.j7m.middleware.codec.api.ValueCodec

Deterministic Phase 1 value codec.

The codec preserves common immutable values, lists, string-keyed maps, enums, exceptions as safe descriptors, explicit ObjectRef handles, and a small allow-list of trusted schema records used by executable examples. Applications may explicitly register DTO/record schemas with trusted extractor/factory functions. Adjacent versions may add or remove optional fields; payload validation finishes before the target factory runs. Unregistered records are rejected because accessors and constructors are application code. The codec never loads classes from wire type names and does not use Java native serialization.
