Question

我想知道是否有任何方法可以过滤已经过滤的商店。让我们说我有一个网格和两个过滤器（F1和F2）。现在，我正在做的是

if(!F1 & !F2)
{
grid.store.load().filterBy(function(record, id){
                /*** My function to sort the entire store ***/
            }, this);
}
else if(F1 & !F2){
grid.store.load().filterBy(function(record, id){
                    /*** My function to sort the entire store ***/
                }, this);
}
else if (!F1 & F2) {
grid.store.load().filterBy(function(record, id){
                    /*** My function to sort the entire store ***/
                }, this);
}
else if (F1 & F2){
grid.store.load().filterBy(function(record, id){
                    /*** My function to sort the entire store ***/
                }, this);
}

我为该网格添加了越来越多的过滤器以及＆＃39; else if＆＃39;正以指数方式增长...... 此外，我在150k +记录上过滤，因此重置＆amp;＆amp;在任何更改时过滤所有记录都可能非常昂贵。

我想要的是

if (F1){
 /** filter on the most recent version of the grid **/
}
if (F2){
/** filter on the most recent version of the grid **/
}

希望我很清楚，谢谢。

使用System.out.println(gsonOptFact.toJson(new BasicObjectOptional(true))); // {"someKey":"someValue","someNumber":42,"mayBeNull":null} System.out.println(gsonOptFact.toJson(new ComplexObjectOptional(true))); // {"theTitle":"Complex Object","stringArray":["Hello","World"],"theObject":{"someKey":"someValue","someNumber":42,"mayBeNull":null}} // Now read back in: String basic = "{\"someKey\":\"someValue\",\"someNumber\":42,\"mayBeNull\":null}"; String complex = "{\"theTitle\":\"Complex Object\",\"stringArray\":[\"Hello\",\"world\"],\"theObject\":{\"someKey\":\"someValue\",\"someNumber\":42,\"mayBeNull\":null}}"; String complexMissing = "{\"theTitle\":\"Complex Object\",\"theObject\":{\"someKey\":\"someValue\",\"mayBeNull\":null}}"; BasicObjectOptional boo = gsonOptFact.fromJson(basic, BasicObjectOptional.class); System.out.println(boo); // someKey = Optional[someValue], someNumber = Optional[42], mayBeNull = Optional.empty ComplexObjectOptional coo = gsonOptFact.fromJson(complex, ComplexObjectOptional.class); System.out.println(coo); // theTitle = Optional[Complex Object], stringArray = Optional[[Optional[Hello], Optional[world]]], theObject = (Optional[someKey = Optional[someValue], someNumber = Optional[42], mayBeNull = Optional.empty]) ComplexObjectOptional coom = gsonOptFact.fromJson(complexMissing, ComplexObjectOptional.class); System.out.println(coom); // theTitle = Optional[Complex Object], stringArray = null, theObject = (Optional[someKey = Optional[someValue], someNumber = null, mayBeNull = Optional.empty])。

Fiddle

store.getFilters().add()

过滤已过滤的商店
