Class RulesDelegate

java.lang.Object
org.mybatis.generator.internal.rules.RulesDelegate
All Implemented Interfaces:
Rules
public class RulesDelegate extends Object implements Rules
This class can be used by plugins to easily implement a custom rules implementation. Plugins should respect the rules implementation calculated by the generator, as well as implementations from other plugins. In general if something is disabled by the default rules, or is disabled by some other plugin, it should not be re-enabled. Therefore, the following pattern of use is recommended: 
public class MyPlugin extends PluginAdapter {
  @Override
  public void initialized(IntrospectedTable introspectedTable) {
    MyRules myRules = new MyRules(introspectedTable.getRules());
    introspectedTable.setRules(myRules);
  }
}

public class MyRules extends RulesDelegate (
  public MyRules(Rules rules) {
    super(rules);
  }

  @Override
  public boolean generateInsert() {
    boolean rc = super.generateInsert();
    if (rc) {
      // Other plugins, and the default rules, enable generation
      // of the insert method.  We can decide to disable it here
      // if needed.
    }

    return rc;
  }
