I have one parent Map and want to divide it with some logic.
let m = Map();
let sub1 = m.filter((el) => el.isFiltered());
How can I get the rest of the Map? I know that I can invert condition inside filter, but I want to know if there is some method which is analogue to _.difference in underscore?
You can use groupBy to get both subsets with one iteration round:
let m = Map();
let grouped = m.groupBy((el) => el.isFiltered());
let pass = grouped.get(true)
let fail = grouped.get(false)

Ok so I have a spreadsheet which we extract a 2d array of values from.
But really I want one variable per line of this 2d array.
The following code does work... but is this the best way to do it?
function testAssignments(){
config = ss.getRange("C2:C6").getValues();//2D Array
result = []
config.forEach(x => result.push(x[0]))
var [a,b,c,d,e] = result;
console.log(a,b,c,d,e);
}
I also tried the line config.forEach(x=> x=x[0]) but that didn't work for some reason.
Use .flat instead of .forEach and .push. If you want a different variable name for each element, there isn't a better way.
const [a,b,c,d,e] = ss.getRange("C2:C6").getValues().flat();//1D Array
//or
const [[a],[b],[c],[d],[e]] = ss.getRange("C2:C6").getValues();
My current table looks like this:
Status
Draft
Pending
Complete
I want to sort them based on the value of the cells. Is there a way to do that? I've only been able to sort them using this code:
onChange(status: string){
const sortState: Sort = {active: status, direction: 'desc'};
this.sort.active = sortState.active;
this.sort.direction = sortState.direction;
this.sort.sortChange.emit(sortState);
}
But I want to sort using the values of the status themselves since I'd want to create a button which when click sorts starting from complete or draft or pending.
I'm a little confused by your question, but I think I understand what you're asking.
You're going to want to convert your values into an array and then use the .sort() function. So, assuming you have an array of your cells, we can call that let array = Cell[], you can then access the status of the cells like this:
sortCells(){
let array = Cell[]; // here we're assuming there is already a cell type and a cell.active parameter, like shown in your example.
let possibleValues = ["Draft","Pending","Complete"]; // easier way to compare two values
array.sort((a,b)=>{
let aIndex = possibleValues.indexOf(a.active); // index of gets the location of the element in an array
let bIndex = possibleValues.indexOf(b.active);
if(a > b){
return -1;
} else if(b > a){
return 1;
}else{
return 0; // they are equal
}
})
}

how to get Quantities of selected object, like you can see here: https://imgur.com/71Rm0Y4 ?
#PetrBroz helped me to get Properties of selected object (He's example is here:
) but I also need to get Quantities: https://imgur.com/71Rm0Y4
Thank you.
You'll need to traverse the instance tree to find the parent you're interested in. In your example, it would be something like this:
const ids = viewer.getSelection();
if (ids.length > 0) {
const instanceTree = viewer.model.getData().instanceTree;
let id = ids[0];
id = instanceTree.getNodeParentId(id);
id = instanceTree.getNodeParentId(id);
id = instanceTree.getNodeParentId(id);
// Or better, traverse the parents in a while loop until you find one that matches your requirements
viewer.getProperties(id, function(props) {
console.log(props);
});
}
For those who don't know what the Kairos SDK is, it's basically a facial recognition api.
When you give it an image, it will tell you who if they can match you with someone in the database.
When i give it an image; the api sends me back this response:
[images: (
{
attributes = {
gender = {
confidence = "80%";
type = F;
};
};
candidates = (
{
"enrollment_timestamp" = 1436883322;
face3rd = "0.988351106643677";
},
{
"enrollment_timestamp" = 1436883214;
hi = "0.94137054681778";
},
{
"enrollment_timestamp" = 1436883132;
hi = "0.94137054681778";
}
);
time = "6.43676";
transaction = {
confidence = "0.988351106643677";
"distance_apart" = "0.046980559825897";
"gallery_name" = test1;
height = 482;
"matching_threshold" = "0.4";
"next_subject" = hi;
"next_subject_confidence" = "0.94137054681778";
"simularity_threshold" = "0.1";
status = success;
subject = face3rd;
topLeftX = 148;
topLeftY = 92;
width = 482;
};
}
)]
What i have done is put three images in the database and have called each of them respectively, face3rd, hi, hi (sorry for the two hi's)
I have been trying to parse the names and the number next to it for soo long, i can get around the 6 second response time.
The reason i have not been able to get the names is because, as you can see, i don't know what to tell Swift to look for. The image name changes depending on who i get back.
I don't know if i've explained my situation, bestly, but if you look at the response. The parts that say:
face3rd = "0.988351106643677";
hi = "0.94137054681778";
hi = "0.94137054681778";
I need the information on both sides of the equal sign.
Thank you for your help and apologise, if reading it was pedantic or you felt like their was a lot of repetion.
Thanks!
Yes, it is poorly formatted JSON that we are returning. We will fix it in an upcoming version of the API (no release date at this time..sorry).
If all you need is the closest match, you can just access the subject variable directly and ignore the candidates array.
Otherwise, you would need to parse the candidates array manually unfortunately. I'm not sure how to do that in Swift.
Introduction:
I have an AdvancedDataGrid displaying hierarchical data illustrated by the image below:
The branch nodes "Prosjekt" and "Tiltak" display the sum of the leaf nodes below.
Problem: I want the root node "Tavle" to display the total sum of the branch nodes below. When i attempted to do this by adding the same SummaryRow the sum of the root node was not calculcated correctly(Every node's sum was calculated twice).
dg_Teknikktavles = new AutoSizingAdvancedDataGrid();
dg_Teknikktavles.sortExpertMode="true";
dg_Teknikktavles.headerHeight = 50;
dg_Teknikktavles.variableRowHeight = true;
dg_Teknikktavles.addEventListener(ListEvent.ITEM_CLICK,dg_TeknikktavlesItemClicked);
dg_Teknikktavles.editable="false";
dg_Teknikktavles.percentWidth=100;
dg_Teknikktavles.minColumnWidth =0.8;
dg_Teknikktavles.height = 1000;
var sumFieldArray:Array = new Array(context.brukerList.length);
for(var i:int = 0; i < context.brukerList.length; i++)
{
var sumField:SummaryField2 = new SummaryField2();
sumField.dataField = Ressurstavle.ressursKey + i;
sumField.summaryOperation = "SUM";
sumFieldArray[i] = sumField;
}
var summaryRow:SummaryRow = new SummaryRow();
summaryRow.summaryPlacement = "group";
summaryRow.fields = sumFieldArray;
var summaryRow2:SummaryRow = new SummaryRow();
summaryRow2.summaryPlacement = "group";
summaryRow2.fields = sumFieldArray;
var groupField1:GroupingField = new GroupingField();
groupField1.name = "tavle";
//groupField1.summaries = [summaryRow2];
var groupField2:GroupingField = new GroupingField();
groupField2.name = "kategori";
groupField2.summaries = [summaryRow];
var group:Grouping = new Grouping();
group.fields = [groupField1, groupField2];
var groupCol:GroupingCollection2 = new GroupingCollection2();
groupCol.source = ressursTavle;
groupCol.grouping = group;
groupCol.refresh();
Main Question: How do i get my AdvancedDataGrid's (dg_Teknikktavles) root node "Tavle" to correctly display the sum of the two branch nodes below?
Side Question: How do i add a red color to the numbers of the root node's summary row that exceed 5? E.g the column displaying 8 will exceed 5 in the root node's summary row, and should therefore be marked red
Thanks in advance!
This is a general answer, without code examples, but I had to do the same just couple of days ago, so my memory is still fresh :) Here's what I did:
Created a class A to represent an item renderer data, extended it from Proxy (I had field names defined at run time), and let it contain a collection of values as it's data member. Once accessed through flash_proxy::getPropery(fieldName) it would find a corresponding value in the data member containing the values and return it. Special note: implement IUID, just do it, it'll save you couple of days of frustration.
Extended A in B, added a children property containing ArrayCollection of A (don't try to experiment with other collection types, unless you want to find yourself examining tons of framework code, trust me, it's ugly and is impossible to identify as interesting). Let B override flash_proxy::getPropery - depending of your compiler this may, or may not be possible, if not possible - call some function from A.flash_proxy::getPropery() that you can override in B. Let this function query every instance of A, which is a child of B, asking the same thing, as DataGrid itself would, when building item renderers - this way you would get the total.
When creating a data provider. Create an ArrayCollection of B (again, don't try to experiment with other collections--unless you are ready for lots of frustration). Create Hierarchical data that uses this array collection as a source.
Colors - that's what you use item renderers for, just look up any tutorial on using item renderers, that must be pretty basic.
In case someone else has the same problem:
The initial problem that everything was summed twice, was the result of using the same Array of SummaryField2 (sumFieldArray in the code) for both grouping fields(GropingField2 tavle and kategori)
The Solution to the main question: was to create a new array of summaryfields for the root node(in my intial for loop):
//Summary fields for root node
var sumFieldRoot:SummaryField2 = new SummaryField2();
sumFieldRoot.dataField = Ressurstavle.ressursKey + i;
sumFieldRoot.summaryOperation = "SUM";
sumFieldArrayRoot[i] = sumFieldRoot;
Answer to the side question:
This was pretty much as easy as pointed out by wvxyw. Code for this solution below:
private function summary_styleFunction(data:Object, col:AdvancedDataGridColumn):Object
{
var output:Object;
var field:String = col.dataField;
if ( data.children != null )
{
if(data[field] >5){
output = {color:0xFF0000, fontWeight:"bold"}
}
else {
output = {color:0x006633, fontWeight:"bold"}
}
//output = {color:0x081EA6, fontWeight:"bold", fontSize:14}
}
return output;
}
