开放过程中不是不建议用多个if并列嘛，那阿里fastjson源码中会有如下片段呢？

com.alibaba.fastjson.serializer.SerializeFilterable.addFilter(SerializeFilter)
这个方法中用连续9个if，这样写是合理的，还是有待优化呢？求权威分析……

public void addFilter(SerializeFilter filter) {
    if (filter == null) {
        return;
    }
    
    if (filter instanceof PropertyPreFilter) {
        this.getPropertyPreFilters().add((PropertyPreFilter) filter);
    }
    
    if (filter instanceof NameFilter) {
        this.getNameFilters().add((NameFilter) filter);
    }
    
    if (filter instanceof ValueFilter) {
        this.getValueFilters().add((ValueFilter) filter);
    }
    
    if (filter instanceof ContextValueFilter) {
        this.getContextValueFilters().add((ContextValueFilter) filter);
    }
    
    if (filter instanceof PropertyFilter) {
        this.getPropertyFilters().add((PropertyFilter) filter);
    }
    
    if (filter instanceof BeforeFilter) {
        this.getBeforeFilters().add((BeforeFilter) filter);
    }
    
    if (filter instanceof AfterFilter) {
        this.getAfterFilters().add((AfterFilter) filter);
    }
    
    if (filter instanceof LabelFilter) {
        this.getLabelFilters().add((LabelFilter) filter);
    }
}
