Hello,
I am attempting to put a statement in my .mxml file to make a private function restart if a certain condition is met. I am not pro at coding in .mxml, but I believe I have a start at solving this issue. Below it the code for my function, up to the point that the code would restart, if the condition is true:
private function populateLayerDataDictionary():void
{
//the smallest and largest scales reasonably possible
var smallestScale:Number = map.lods ? map.lods[0].scale : 1000000000;
var largestScale:Number = map.lods ? map.lods[map.lods.length - 1].scale : 1;
var data:Object;
var priority:int = 0;
var agsVersion:Number;
// The next line controls whether the proxy in the <httpproxy> tag in config.xml
// is used for each layer. If want this set it to true; otherwise set it to false.
// If there is no <httpproxy> tag in config.xml then the value of useProxy doesn't matter.
var useProxy:Boolean = true;
for each (var layer:Layer in map.layers)
{
trace(layer.id);
if (layer is ArcGISDynamicMapServiceLayer)
{
var dmsLayer:ArcGISDynamicMapServiceLayer = layer as ArcGISDynamicMapServiceLayer;
if (useProxy) dmsLayer.proxyURL = configData.proxyUrl;
agsVersion = dmsLayer.version;
if (isNaN(agsVersion))
{
// This happens if the map includes a service that is turned off or doesn't exist
mapServicesProcessed++;
continue;
}
//make an object for this map service to hold the layer information
var dmsMapServiceObj:Object = {id: dmsLayer.id, layers: new Array(), priority: priority++, url: dmsLayer.url, token: dmsLayer.token, proxyUrl: dmsLayer.proxyURL};
//add the map service object to the array of map services
mapServicesArray.push(dmsMapServiceObj);
// set the max and min scales
var maxScale:Number = layer.maxScale;
var minScale:Number = layer.minScale;
var getScales:Boolean = (maxScale == 0 && minScale == 0);
if (getScales)
{
for each (var layerInfo:LayerInfo in dmsLayer.layerInfos)
{
if (layerInfo.maxScale > 0 && (maxScale == 0 || layerInfo.maxScale < maxScale)) maxScale = layerInfo.maxScale;
if (layerInfo.minScale > 0 && layerInfo.minScale > minScale) minScale = layerInfo.minScale;
}
layer.maxScale = maxScale > 0 ? maxScale : largestScale;
layer.minScale = minScale > 0 ? minScale : smallestScale;
}
data = {name: dmsLayer.name, url: dmsLayer.url, token: dmsLayer.token, rtDefExpr: "", proxyUrl: dmsLayer.proxyURL};
dmsLayer.getAllDetails(new AsyncResponder(onResult, onFault, data));
}
else if (layer is ArcGISTiledMapServiceLayer)
{
var tmsLayer:ArcGISTiledMapServiceLayer = layer as ArcGISTiledMapServiceLayer;
if (useProxy) tmsLayer.proxyURL = configData.proxyUrl;
agsVersion = tmsLayer.version;
if (isNaN(agsVersion))
{
// This happens if the map includes a service that is turned off or doesn't exist
mapServicesProcessed++;
continue;
}
//make an object for this map service to hold the layer information
var tmsMapServiceObj:Object = {id: tmsLayer.id, layers: new Array(), priority: priority++, url: tmsLayer.url, token: tmsLayer.token, proxyUrl: tmsLayer.proxyURL};
//add the map service object to the array of map services
mapServicesArray.push(tmsMapServiceObj);
if (layer.maxScale == 0 && layer.minScale == 0 && tmsLayer.tileInfo)
{
layer.maxScale = tmsLayer.tileInfo.lods[tmsLayer.tileInfo.lods.length - 1].scale;
layer.minScale = tmsLayer.tileInfo.lods[0].scale;
}
data = {name: tmsLayer.name, url: tmsLayer.url, token: tmsLayer.token, rtDefExpr: "", proxyUrl: tmsLayer.proxyURL};
tmsLayer.getAllDetails(new AsyncResponder(onResult, onFault, data));
}
else if (layer is FeatureLayer)
{
var feaLayer:FeatureLayer = layer as FeatureLayer;
var layerDetails:LayerDetails = feaLayer.layerDetails;
var tableDetails:TableDetails = feaLayer.tableDetails;
if (layerDetails)
agsVersion = layerDetails.version;
else if (tableDetails)
agsVersion = tableDetails.version;
else
agsVersion = NaN;
if (isNaN(agsVersion))
{
// This happens if the map includes a service that is turned off or doesn't exist
mapServicesProcessed++;
continue;
}
var url:String = feaLayer.url;
var pos:int = url.lastIndexOf("/");
url = url.slice(0, pos);
//make an object for this map service to hold the layer information
var feaMapServiceObj:Object = {id: feaLayer.id, layers: new Array(), priority: priority++, url: url, token: feaLayer.token, proxyUrl: feaLayer.proxyURL};
//add the map service object to the array of map services
mapServicesArray.push(feaMapServiceObj);
data = {name: feaLayer.name, url: url, token: feaLayer.token, rtDefExpr: feaLayer.definitionExpression, proxyUrl: feaLayer.proxyURL};
var allDetails:AllDetails = new AllDetails();
allDetails.layersDetails = [layerDetails];
allDetails.tablesDetails = [tableDetails];
onResult(allDetails, data);
}
else
{
// skip other kinds of layers (e.g. image services)
mapServicesProcessed++;
}
// restarts and repeats populateLayerDataDictionary if there are missing services
if (mapServicesArray.length < 13)
{
init (private function populateLayerDataDictionary);
}
}
The last five lines are devoted to making the function restart itself if the condition 'mapServicesArray.length < 13'. The line 'init (private function populateLayerDataDictionary);' is supposed to trigger the restart, but I am not sure how to do it (this code clearly doesn't, it is a test of mine). Any advice would be welcome.
Thank you in advance! (and sorry for my poor code formatting in this post!)
