I am trying to do a similar simulation to this.
Parking randomly in Anylogic
in addition, I would also want to generate graphs for the output
i.e total number of cars leaving the car park garage.
I am facing the issue of
"Description: Parameter type is not specified" under the "isThereParking" function from the solution above.
Also the error "Description: Void methods cannot return a value.- Function"
for the "selectRandomParkinSpace" Function
What should be the return for both these functions?
Thank you for helping!
boolean
isThereParking( ~Object~ ) {
for(ParkingLot p : parkingSpaces){
if(p.nFree()>0)
return true;
}
return false;
}
Description: Syntax error, insert "... VariableDeclaratorId" to complete FormalParameterList. - Agent Type
It seems to me that you are not sure how to properly set up a function with the graphical function symbol. The function name, input and output parameters are defined in the fields of the function's properties section, not in the code itself if you use this module.
Have a look at the screenshot:
I marked the name definition, the return parameter definition and then the input parameter definition.
One thing that is unclear to me however is why you want an input parameter of type object, but do not give it a name or use it for anything...not sure what you want to do with this.

I'm trying to create a custom outliner for VSCode (currently only for python), but I don't find measures to get the information I needed.
I like to get information in this manner this:
Array:
[0]
label: "foo"
type: "Function"
parameters: [...]
Range: [...]
innerDefinitions: [0]
[1]
label: "myclass"
type: "Class"
base_class: ""
Range: [...]
innerDefinitions:
[0]:
[...]
[1]:
[...]
Currently I try to get outline information via vscode.commands.executeCommand( 'vscode.XXX'
What I've tried:
Here is what commands I've tried and what result I received.
vscode.executeImplementationProvider
half usable: range of functionname. Other information is missing
vscode.executeHoverProvider
half usable: string of function head (including def keyword)
vscode.executeDefinitionProvider
half usable: range of complete function. Individual information must be "parsed out"
vscode.executeTypeDefinitionProvider
Never provided any result
vscode.executeDeclarationProvider
Never provided any result
vscode.executeDocumentSymbolProvider
Goes in a good direction. However
(1) Does only work on the whole document (not single function)
(2) Does only return first-level entities (i.e. class methods are not included in result)
Is there any API call I've overseen?
I wonder how the built-in outliner works, as it contains all-level information.
You need to use vscode.commands.executeCommand<vscode.Location[]>("vscode.executeDocumentSymbolProvider", uri, position)
This will give you the full outline of one file. There is no way to receive a partial outline.
Note: innerDefinitions are called children here.
Regarding the detail of the outline:
How detailed (and correct) an outline is going to be, depends on the implementation of the provider. Also, provider's information is no necessarily consistent among languages. This is very important to keep in mind!
At the moment (2021/03), the standard SymbolProvider for...
... Python will have a child for each parameter and local variable of a function. They will not be distinguishable
... C++ will contain no children for parameters. But it will have the parameter types in its name. (e.g. name of void foo(string p) will be foo(string): void.
As you can see, both act differently with their own quirks.
You could create and register a DocumentSymbolProvider yourself, that would return a level of detail you need (see VSCode Providers)

i need to forward an agent to a specific service depending on a cycle written in a database; in the model, i have written the following code:
serviceTo = selectFrom(ciclo)
.where(ciclo.sequenza.eq(agent.sequenza))
.where(ciclo.sku.eq(agent.SKU))
.uniqueResult(ciclo.service);
serviceTo.take(agent)
the problem is that: "serviceTo" is a string and the method take is not working with that. how can i use the "serviceTo" variable in order to deliver the agent to the right enter?
You will need to parse your value, eg. convert your string serviceTo, that you retrieve from the database to a Java/AnyLogic object of type Enter.
In order to do so, create a Collection allMyEntersCollecton of type Enter and add all your Enter-objects that you want to be able to parse. You can also do this by selecting all your Enter blocks, right click, and use create Collection.
Create a parsing function parseEnter that returns a result of type Others/Enter and takes an input parameter serviceTo of type String:
for(int i=0;i<allMyEntersCollection.size();i++){
if(allMyEntersCollection.get(i).getName().equalsIgnoreCase(serviceTo)){
return allMyEntersCollection.get(i);
}
}
//nothing found, will probably cause a NullPointerException later:
return null;
Now all you have to do is to run this function parseEnter with your parameters:
Enter serviceToObject = parseEnter(serviceTo);
Of course the parsing only works if the String really contains exactly the name of any of the Enter objects in your Collection.
Use the resulting Enter-object:
serviceToObject.take(myExampleAgent);
I have written a macro for ImageJ/FIJI to deconvolve my confocal microscopy images and run the "3D Object Counter" plugin. The macro successfully runs all required commands and saves all required data in the specified places.
However, I have found that the 3D-OC autothreshold (as shown in the plugin dialog box) is to stringent resulting in objects being lost or divided.
To remedy this I would like to reduce the autothreshold by a predetermined function something similar to what was done here (from:How to get threshold value used by auto threshold Plugin) which resulted in this code:
setAutoThreshold();
getThreshold(lower,upper);
v=setThreshold(lower,upper*0.5);
run("3D Objects Counter", "threshold="v" slice=10 min.=400 max.=20971520 objects statistics summary");
The idea was to call the AutoThreshold values, modify them and set them to a variable. However when these lines are run the following error is returned:
Number or numeric function expected in line 3.
v=<setThreshold>(lower,upper*0.5);
And if the variable is inserted directly into the threshold key for run(3D-OC) the following msg is encountered:
Numeric value expected in run() function
Key:"threshold"
Value or variable name:"setThreshold(lower,upper*0.5"
Any suggestions or help on how to designate the 3D-OC threshold value as a variable as described would be greatly appreciated (as would any work arounds of course :) ).
Cheers
Edit: After testing Jan's response below (which works perfectly), it appears I need to call the threshold set by the 3D-OC plugin. Anyone know how to do this?
The getThreshold(lower, upper) function returns the lower and upper threshold levels in the provided variables. There is no need to assign any value to a new variable, and as you observed, setThreshold does not have any return value.
Instead, you can use the value(s) returned from getThreshold and use them as parameters in the run method (in the correct way, by string concatenation, see here):
setAutoThreshold();
getThreshold(lower, v);
run("3D Objects Counter", "threshold=" + v + " slice=10 min.=400 max.=20971520 objects statistics summary");
Alternatively, you can use &v in the second parameter to avoid string concatenation in the last line (see the documentation for the run() macro function):
run("3D Objects Counter", "threshold=&v slice=10 min.=400 max.=20971520 objects statistics summary");
You might have to use the lower instead of the upper threshold value, depending on whether you count bright or dark objects.
After a few hours searching, I couldn't find any solution to this little problem I'm having.
I have a query that retrieves one of its criteria from a form. I have referenced correctly the value on the form from the query, and it works, but what I wanted to do is a bit more complicated: when the form is closed, I want to launch the query with a "default value".
I tried to do it in 2 different ways:
a) Defining an "IIf" at the query criteria: I would need a function that checks if the form from which I retrieve the values is open.
b) Defining public variables with a default value, which would be changed from the form: I don't know where/when to initialize the value of the variable.
Does anyone have a better idea on how to do this?
TL;DR: Query gets criteria from form when it's open. If form is closed, query uses default value. HELP!
You can create a VBA function in a module to do this :
Function MyCriterion() As Long
MyCriterion = 1234 ' default value
If CurrentProject.AllForms("MyForm").IsLoaded Then
MyCriterion = Forms("MyForm").MyControl.Value
End If
End Function
I have a SSRS "statement" type report that has general layout of text boxes and tables. For the main text box I want to let the user supply the value as a parameter so the text can be customized, i.e.
Parameters!MainText.Value = "Dear Mr.Doe, Here is your statement."
then I can set the text box value to be the value of the parameter:
=Parameters!MainText.Value
However, I need to be able to allow the incoming parameter value to include a dataset field, like so:
Parameters!MainText.Value = "Dear Mr.Doe, Here is your [Fields!RunDate.Value] statement"
so that my report output would look like:
"Dear Mr.Doe, Here is your November statement."
I know that you can define it to do this in the text box by supplying the static text and the field request, but I need SSRS to recognize that inside the parameter string there is a field request that needs to be escaped and bound.
Does anyone have any ideas for this? I am using SSRS 2008R2
Have you tried concatenating?
Parameters!MainText.Value = "Dear Mr.Doe, Here is your" & [Fields!RunDate.Value] & "statement"
There are a few dramatically different approaches. To know which is best for you will require more information:
Embedded code in the report. Probably the quickest to
implement would be embedded code in the report that returned the
parameter, but called String.Replace() appropriately to substitute
in dynamic values. You'll need to establish some code for the user for which strings will be replaced. Embedded code will get you access to many objects in the report. For example:
Public Function TestGlobals(ByVal s As String) As String
Return Report.Globals.ExecutionTime.ToString
End Function
will return the execution time. Other methods of accessing parameters for the report are shown here.
1.5 If this function is getting very large, look at using a custom assembly. Then you can have a better authoring experience with Visual Studio
Modify the XML. Depending on where you use
this, you could directly modify the .rdl/.rdlc XML.
Consider other tools, such as ReportBuilder. IF you need to give the user
more flexibility over report authoring, there are many tools built
specifically for this purpose, such as SSRS's Report Builder.
Here's another approach: Display the parameter string with the dataset value already filled in.
To do so: create a parameter named RunDate for example and set Default value to "get values from a query" and select the first dataset and value field (RunDate). Now the parameter will hold the RunDate field and you can use it elsewhere. Make this parameter hidden or internal and set the correct data type. e.g. Date/Time so you can format its value later.
Now create the second parameter which will hold the default text you want:
Parameters!MainText.Value = "Dear Mr.Doe, Here is your [Parameters!RunDate.Value] statement"
Not sure if this syntax works but you get the idea. You can also do formatting here e.g. only the month of a Datetime:
="Dear Mr.Doe, Here is your " & Format(Parameters!RunDate.Value, "MMMM") & " statement"
This approach uses only built-in methods and avoids the need for a parser so the user doesn't have to learn the syntax for it.
There is of course one drawback: the user has complete control over the parameter contents and can supply a value that doesn't match the report content - but that is also the case with the String Replace method.
And just for the sake of completeness there's also the simplistic option: append multiple parameters: create 2 parameters named MainTextBeforeRunDate and MainTextAfterRunDate.
The Textbox value expression becomes:
=Parameters!MainTextBeforeRunDate.Value & Fields!RunDate.Value & Parameters!MainTextAfterRunDate.Value.
This should explain itself. The simplest solution is often the best, but in this case I have my doubts. At least this makes sure your RunDate ends up in the final report text.
