Re: [Simple-support] Boolean Attribute 0 or 1

There is a RegistryMatcher, just use this. Register your classes with it. Its available in 2.6.2.

Hello back,

i implemented a Matcher as you proposed, but i need a Matcher that 
Transform many different Type of data (Transform<Float>, 
Transform<Integer> and Transform<Boolean>).

how can i do this with a single implementation of Matcher class ?

my Matcher , with a single transformer, so far :

public class LigneArticleFloatMatcher implements Matcher, Transform<Float> {

     @Override
     public Float read(String value) throws Exception {
         if((value!="null")&&(value!=""))
         {
             try{
                 return Float.valueOf(value);
             }catch(Exception e){
                 return 0f;
             }
         }else{
             return 0f;
         }
     }

     @Override
     public String write(Float value) throws Exception {
         return String.valueOf(value);
     }

     @SuppressWarnings("rawtypes")
     @Override
     public Transform match(Class type) throws Exception {
         if(type == Float.class) {
             return this;
          }
         return null;
     }

}

Thanks in advance ^^
