Interface RequestParameterTransformer

All Known Implementing Classes:

AbstractAliasHandler, AbstractParameterTransformer, DirectoryLoader.AliasHandler, InlineCssParameterTransformer, InlineScriptParameterTransformer, InterfaceScanner.AliasHandler, JavaSourceLoader.AliasHandler, MacroPresetParameterTransformer, MessageBoxParameterTransformer, PropertiesLoader.AliasHandler, ScriptInvoker.AliasHandler, SvgLoader.AliasHandler, TabbedPanelParameterTransformer, TableLayoutParameterTransformer, XmlLoader.AliasHandler

public interface RequestParameterTransformer

RequestParameterTransformer defines an interface that may be implemented and registered via service loading to plug parameter transformers that adjust macro parameters on the fly before any other operation is triggered.

Implementation:

 package my.package;
 public class MyRequestParameterTransformer implements RequestParameterTransformer {
      public void transformParameters(Map<String, Object> requestParams) {
          Object value = requestParams.get("my-input-param");
          if (value != null) {
              requestParams.put("myText", value);
              requestParams.put("source", "classpath:my-template.vm");
          }
      }
 }
 

Register the implementation using service loading:

• Create the following file:

   META-INF/services/ org.tinyjee.maven.dim.spi.RequestParameterTransformer 

• Add the fully qualified class name of your implementation to the file "org.tinyjee.maven.dim.spi.RequestParameterTransformer":

   my.package.MyRequestParameterTransformer
