getting filteredItems

[Emanuele Ziglioli]

Hi again,

I'd like to fetch the filteredItems array from a dataview in order to
display it on a map.
Currently I can get the size of the dataview filtered rows and a
single item, or the whole lot.
But I can't get to filteredItems (it's private). Maybe there's a way
in Javascript (there must be a way, it's js!), currently trying with:

dataview.__proto__getFilteredItems = function(){
return filteredItems;
};

Any js ninja out there?

Cheers
E

Filtered items are exposed by the DataView via the "getItem(index)" and "getLength()" methods.

thank you, am a bit allergic to getters, coming from the java
world :-)
it would be nice to be able to access the whole array though, I could
display things all at once or calculate things like the data extent
without having to copy the whole array.
Next I want to understand how grouping works, that could be useful.
