code: @Override
      public Boolean parameterAsBoolean(String name) {
          String parameter = parameter(name);
          try {
              return Boolean.parseBoolean(parameter);
          } catch (Exception e) { //NOSONAR
              return false;
          }
      }
docs: Like {@link #parameter(String)}, but converts the parameter to
  Boolean if found.
  <p/>
  The parameter is decoded by default.
  
  @param name The name of the post or query parameter
  @return The value of the parameter or {@literal false} if not found.
