To take any attribute of a JSF component just have an instance of the type UIComponent of the same, than with the method getAttributes() returns any desired attribute by passing only one key to the Map<String, Object>returned.

For your problem it can be used like this:

UIComponent dt = FacesContext.getCurrentInstance().getViewRoot().findComponent("IdForm:IdDataTable");
boolean lazy = (boolean)dt.getAttributes().get("lazy"));
