Configuration

The wrapper code generator is an annotation processor, provided by the base module.

The maven configuration looks like this:

<dependencies>
<dependency>
<groupId>one.microstream</groupId>
<artifactId>base</artifactId>
<version>02.02.00-MS-GA</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<encoding>UTF-8</encoding>
<annotationProcessors>
<annotationProcessor>one.microstream.wrapping.codegen.WrapperProcessor</annotationProcessor>
</annotationProcessors>
<compilerArgs>
<arg>-Amicrostream.wrapper.types=one.microstream.persistence.types.PersistenceStoring</arg>
</compilerArgs>
</configuration>
</plugin>
</plugins>
</build>

There are following ways to get the base wrapper types generated. If you want it for your own types, the best way is to use the GenerateWrapper annotation.

@GenerateWrapper
public interface MyInterface
{
public void doStuff();
public String getStuff();
}

Or, if you want it for interfaces in libraries, like PersistenceStoring, you cannot add an annotation. That's what the microstream.wrapper.types parameter is for. This is just a comma separated list of types. Alternatively you can use the GenerateWrapperFor annotation:

@GenerateWrapperFor("one.microstream.persistence.types.PersistenceStoring")
public class WrapperGenerationDummy
{
}

It accepts a list of type names. Plain strings have to be used instead of class literals, because it is read inside the compilation cycle which prohibits access to class elements.
