Interface ChangeTemplateFactory

public interface ChangeTemplateFactory

Service provider interface for factories that produce ChangeTemplate instances.

This interface enables a federated approach to template discovery, allowing modules to provide multiple templates through a single service provider. Implementations of this interface are discovered via Java's ServiceLoader mechanism during both:

• GraalVM build-time processing for native image reflection registration
• Runtime template discovery and registration

To register a factory implementation, create a file at: META-INF/services/io.flamingock.internal.common.core.template.ChangeTemplateFactory containing the fully qualified class name of your implementation.

Factory implementations should be stateless and thread-safe, as they may be instantiated multiple times and accessed concurrently.

Method Summary

Modifier and Type	Method and Description
java.util.Collection<io.flamingock.api.template.ChangeTemplate<?,?,?>>	getTemplates() Returns a collection of ChangeTemplate instances provided by this factory.

Method Detail

getTemplates

java.util.Collection<io.flamingock.api.template.ChangeTemplate<?,?,?>> getTemplates()

Returns a collection of ChangeTemplate instances provided by this factory.

This method is called by ChangeTemplateManager.getTemplates() to discover templates in a federated manner. It is invoked in two contexts:

• During GraalVM build-time processing to register template classes for reflection
• During runtime initialization to populate the template registry

Implementations should:

• Create and return new instances of templates each time this method is called
• Not maintain any state between invocations
• Be thread-safe
• Handle any exceptions internally to prevent disrupting the template discovery process

Returns:

A collection of template instances provided by this factory
