Class ConfigMapper

java.lang.Object

org.embulk.util.config.ConfigMapper

public final class ConfigMapper
extends Object

Maps org.embulk.config.ConfigSource into a task-defining interface that inherits Task.

It performs the same job with Embulk core's ConfigSource#loadConfig on plugin's side.

 public class ExampleInputPlugin implements InputPlugin {
     public ExampleInputPlugin() {
         this.configMapperFactory = org.embulk.util.config.ConfigMapperFactory.withDefault();
     }

     public interface PluginTask extends org.embulk.util.config.Task {
         // ...
     }

     public ConfigDiff transaction(final ConfigSource config, final InputPlugin.Control control) {
         final org.embulk.util.config.ConfigMapper configMapper = this.configMapperFactory.createConfigMapper();
         final PluginTask task = configMapper.map(config, PluginTask.class);
         // ...
     }

     // ...

     private org.embulk.util.config.ConfigMapperFactory configMapperFactory;
 }
