Description

Take a look at the code

  @Override
  public boolean isSame(Object o) {
    if (!(o instanceof ExprNodeConstantDesc)) {
      return false;
    }
    ExprNodeConstantDesc dest = (ExprNodeConstantDesc) o;
    if (!typeInfo.equals(dest.getTypeInfo())) {
      return false;
    }
    if (!value.equals(dest.getValue())) {
      return false;
    }

    return true;
  }

value is an Object.
