Annotation Interface AutoProtoSchemaBuilder
SerializationContextInitializer. Annotate a class or interface
extending from SerializationContextInitializer with this annotation and a new concrete public class named
based on className(), having a default no-arguments public constructor will be generated at compile time in
the same package. The implementations of the methods from SerializationContextInitializer will be generated
based on the information provided in the attributes of this annotation.
This annotation is used at compile time annotation processing only and should not be relied upon at runtime, so its
retention is set to RetentionPolicy.CLASS.
NOTE: This annotation can also be used on packages but this kind of usage has been deprecated in 4.3.4 and will be removed in version 5. See IPROTO-157.

Element Details
-
className
String classNameDeprecated.The name of the generated Java implementation class (optional). If missing, the name of the current class plus the "Impl" suffix is assumed by default.- Default:
""
-
schemaFileName
String schemaFileNameDeprecated.The generated Protobuf schema file name (optional). It can contain'/'characters, so it might appear like a relative or absolute file name. Must end with ".proto" suffix. The schema will be registered under this name in theSerializationContextbySerializationContextInitializer.registerSchema(SerializationContext). If missing, the simple name of the annotated class plus the ".proto" suffix will be used by default.- Default:
""
-
schemaFilePath
String schemaFilePathDeprecated.Generated Protobuf schema resource file path (optional). If this is present then a resource file is generated in the designated path, with the given file name, and will be available to the ClassLoader at runtime, otherwise the generated schema file is directly baked as a String constant into the generated class and no resource file is generated.- Default:
""
-
schemaPackageName
String schemaPackageNameDeprecated.Package of the generated Protobuf schema. This is optional. If the package name is not specified then the unnamed/default package is assumed.- Default:
""
-
value
String[] valueDeprecated.A handy alias forbasePackages().valueandbasePackages()are mutually exclusive. SeebasePackages()for usage.- Default:
{}
-
basePackages
String[] basePackagesDeprecated.The list of packages to scan (optional).basePackagesandincludeClasses()are mutually exclusive. The packages are scanned for annotated classes recursively. IfbasePackagesis empty then all packages are considered, starting from root and including the default (unnamed) package. The packages are filtered based on theexcludeClasses()filter. If neitherincludeClasses()norbasePackagesis specified then the entire source path is scanned. Be wary of using this last option in anything but very simple demo projects.- Default:
{}
-
includeClasses
Class<?>[] includeClassesDeprecated.Annotated classes to process (optional). IfincludeClassesis empty, allProtoXyzannotated classes that belong to the packages listed inbasePackages()will be scanned. If neitherincludeClassesnorbasePackages()was specified then the entire source path will be scanned. Be wary of using this last option in anything but very simple demo projects.- Default:
{}
-
excludeClasses
Class<?>[] excludeClassesDeprecated.Classes to be explicitly excluded.excludeClassesandincludeClasses()are mutually exclusive. This can be used together withbasePackages().- Default:
{}
-
autoImportClasses
Deprecated.since 4.3.4. This will be removed in version 5. See IPROTO-158.Indicates if we accept classes not explicitly included by theincludeClasses()orbasePackages()to be auto-detected by reference from the already included classes and to be added automatically. If this is set tofalse(which is the default) it results in a compilation error when such a case is encountered.- Default:
false
-
service
boolean serviceDeprecated.Enable generation of aMETA-INF/servicesfile for the generated implementation class of theSerializationContextInitializerto be loadable by theServiceLoader. This defaults totrue. The ProtoStream library does not make any use of theServiceLoaderto benefit from this mechanism but the user's application is free to use it.- Default:
true
-
marshallersOnly
boolean marshallersOnlyDeprecated.Generate only the marshallers and skip the schema file.The schema is actually always generated at compile time, in memory, so that various validations can be performed at compile time, but with this flag you effectively ensure it finally gets excluded from both the generated source code and the generated resource files and it does not get registered at runtime by this
SerializationContextInitializerimplementation. This flag is useful in cases where you want to register the schema manually for whatever reason or the schema is already provided/registered by other parts of your application.This option conflicts with
schemaFilePath()and they cannot be used together. Also, this option cannot be set totrueif the annotated element is a subtype ofGeneratedSchema, which is expected to always provide a generated schema, as the name implies.- Default:
false
-
dependsOn
Class<? extends SerializationContextInitializer>[] dependsOnDeprecated.TheSerializationContextInitializers that must be executed before this one. Classes or interfaces listed here must implementSerializationContextInitializerand must also be annotated withAutoProtoSchemaBuilder. Classes not annotated withAutoProtoSchemaBuilderwill result in a compilation error.- Default:
{}
-
syntax
ProtoSyntax syntaxDeprecated.Specifies the protobuf syntax used by the generated schema. Defaults toProtoSyntax.PROTO2- Default:
PROTO2
-
ProtoSchemareplacement instead.
