Method Detail

parse

public Object parse(com.google.inject.TypeLiteral<?> type,
                    Parser.Context ctx)
             throws Exception

Description copied from interface: Parser

Parse one or more values to the required type. If the parser doesn't support the required type a call to Parser.Context.next(TypeLiteral, Object) must be done.

Example:

  Parser converter = (type, ctx)  -> {
    if (type.getRawType() == MyType.class) {
      // convert to MyType
      return ...;
    }
    // no luck! move next
    return next.next();
  }
 

It's also possible to create generic/parameterized types too:

  public class MyContainerType<T> {}

  ParamConverter converter = (type, ctx)  -> {
    if (type.getRawType() == MyContainerType.class) {
      // Creates a new type from current generic type
      TypeLiterale<?> paramType = TypeLiteral
        .get(((ParameterizedType) toType.getType()).getActualTypeArguments()[0]);

      // Ask param converter to resolve the new/next type.
      Object result = next.next(paramType);
      return new MyType(result);
    }
    // no luck! move next
    return ctx.next();
  }
