All type assignments in the +codebase go through `SchemaType.Kind` -- the compiler enforces valid types. + +## Design Decisions + +### No default values in the schema + +Default values are NOT extracted from code. There are three layers of defaults in Artemis +(Java field initializers, XML parser overrides, `artemis create` template values) and no +single source of truth that code inspection can capture. Defaults should be obtained by +running `artemis create` + `artemis properties` against a real broker instance. + +The only exceptions are `factoryClassName` / `loginModuleClass` on factory variants, where +the default matches the `const` discriminator -- that's identity, not a runtime default. + +### XSD does not contribute types + +The XSD declares types for XML configuration (`xsd:string` for fields accepting byte notation +like `"10M"`). But broker.properties uses Java types -- `int` fields only accept integers, +`long` fields accept byte notation through a registered converter. The reflection type is +the truth for broker.properties; the XSD type is the truth for XML configs. The schema +generator targets broker.properties, so reflection wins. + +### Factory discriminator as required + const + default + +Factory variant `$defs` set `required: ["factoryClassName"]` (or `loginModuleClass`) so that +JSON Schema `oneOf` correctly discriminates between variants.

Why synthetic nodes?

+ * + *

Artemis uses a map-of-strings pattern for plugin extensibility: a configuration class (e.g. + * {@code TransportConfiguration}, {@code JaasAppConfigurationEntry}) holds a discriminator field + * ({@code factoryClassName}, {@code loginModuleClass}) selecting the implementation, and an opaque + * {@code Map params} whose valid keys depend on which implementation is selected. + * + *

There is no {@code NettyAcceptorFactoryConfiguration.class} with typed bean properties for + * {@code host}, {@code port}, {@code sslEnabled} — those are convention-based string keys looked up + * via {@code params.get("host")} in the implementation code. Same for JAAS: no {@code + * LDAPLoginModuleConfiguration.class} — the 25 LDAP params live as strings in a map, discovered + * from {@code LDAPLoginModule}'s {@code ConfigKey} enum. + * + *

Because the IRBuilder walks the Java class graph via reflection, it only sees the base class + * with its opaque map. The factory-specific params are invisible to reflection. This builder runs + * after the IR is built to create synthetic ClassNodes that reconstruct the type information + * from convention ({@code *_PROP_NAME} constants, {@code ConfigKey} enums) rather than from the + * type system. + * + *

What each variant node contains

+ * + *
    + *
  • All base class properties copied from the reflected ClassNode + *
  • The discriminator field locked to a {@code const} + {@code default} + {@code required} + *
  • The params field enriched with implementation-specific property names from the registry + *
