some idea of how to add filter mechanism to asta4d

filter mechanism draft.java

render.add(".x-num", Filter.formatedNum(121));

interface Filter<S, T> {
    
    public T convert(S s);
    
}

class NumFilter implements Filter<Integer, String>{
    
}

render.add(".x-num", 213);

render.add(".x-num", NumFilter.convert(123));

>> render.add(".x-num", 123, NumFilter.class).add(".x-fff", "xxx");

>> render.add(".x-num", 123, numFilter).add(".x-fff", "xxx");

render.add(".x-num", 123).filter(NumFilter.class).add("xxx", "fff");

render.add(".x-num", 123).addFilter(".x-num", NumFilter.class);
