Using native store's filters instead of featureFilter.

[NeilujD]

I actually work with the "FeatureStore" class and I need to filter my features depending on many attributes but not just just one.

So I decided to override the "onLoad" function to use the native store's filter and it's looks like that :

onLoad: function(store, records, successful, eOpts) {
  this._removing = true;
  store.layer.removeAllFeatures();
  delete this._removing;

  // Array of the records I'll keep for the layer.
  var keepedRecords = [];

  for (var i = 0; i < records.length; i++) {

    var aRecord = records[i];
    var filtersOK = true;

    // I verify if the records match with each filters and, if not, I exclude it from the record's array.
    for (var f = 0; f < store.filters.items.length; f++) {
      var aFilter = store.filters.items[f];
      if (!aFilter.filterFn(aRecord)) {
        filtersOK = false;
        break;
      }
    }
    if (filtersOK) {
      console.log(aRecord);
      keepedRecords.push(aRecord);
    }
  }

  // Finally I add my keeped records to my layer.
  this.addFeaturesToLayer(keepedRecords);
}

For example I have this filter :

{
  property: "myAttribute",
  value: myValue
}

That works perfectly for me. I've just not ever try by modifying my filters yet but I'll do it soon.

Have you another solution tu use many filters in a FeatureStore ?

Thank you in advance,
