I tried another way that made a bit more sense to me.I have successfully loaded an array with the unselected features and am trying to pass their geometries into a query and then pass the query into selectFeatures() For some reason the query is not working out. The alert before query1 shows the right number of unselected points but the alert after the query shows 0. protected function InvertSelBtn_clickHandler(event:MouseEvent):void{
var i:Number = new Number;
var marker:Boolean = false;
//holds all features in the targetLayer
var features:Array = [];
//holds all currently selected features in targetLayer
var selected:Array = [];
//holds all features that are not currently selected - to be selected
var notSelected:Array = [];
//add features that are currently selected to array selected, then clear selection
for(i=0;i<targetLayer.selectedFeatures.length;i++){
var selFeature:Graphic = targetLayer.selectedFeatures;
selected.push(selFeature);
}
//last query selects all points
targetLayer.clearSelection();
//this selects all features
var query:Query = new Query;
query.where = "1=1";
//this.cursorManager.setBusyCursor();
targetLayer.selectFeatures(query,"new",new AsyncResponder(onResult, onFault));
//if select all fails
function onFault(info:Array, token:FeatureLayer = null):void{
Alert.show("Error During Invert Selection.");
}
//if selection is successful
function onResult(info:Array, token:FeatureLayer = null):void{
//upon result of selecting all features, add all features from targetLayer to array features, then clear selection
for(i=0;i<targetLayer.selectedFeatures.length;i++){
var feature:Graphic = targetLayer.selectedFeatures;
features.push(feature);
}
//targetLayer.clearSelection();
//nested for loop to iterate through features (run once for each feature in targetLayer)
//then iterate through selected (run once for each feature in selFeatures)
//if their objects match, marker set to true - if at the end of the inside loop marker is still false
//no match was found and
for(x=0;x<features.length;x++){
for(y=0;y<selected.length;y++){
//if there is ever a match, mark boolean as true, and features wont be added to notSelected
//i will have to change this to work with line, poly -for now points is fine
if(features.geometry as MapPoint === selected.geometry as MapPoint){
marker=true;
}
}
//if match wasnt found in inside for loop, then the feature wasnt selected and will be added to notSelected
if(marker===false){
notSelected.push(features);
}
//speed things up and break the loop if all non selected features have been added
if(features.length<=(selected.length+notSelected.length)){
break;
}
}
//this alert broke the selection screen for some reason lol
//Alert.show("# features selected: " +selected.length.toString()+"+ # features not selected: "+notSelected.length.toString()+"= # features total: "+features.length.toString());
//loop through notSelected, adding each feature in it to selection of targetLayer
targetLayer.clearSelection();
Alert.show(notSelected.length.toString());
var query1:Query = new Query;
query1.geometry = notSelected.geometry;
query1.spatialRelationship=Query.SPATIAL_REL_OVERLAPS;
targetLayer.selectFeatures(query1,"new",null);
Alert.show(targetLayer.selectedFeatures.length.toString());
}
}
