do I need to define the key that gets updated with the new asnwer from the user, or do I set the condition that I need to be satisfied to proceed? The explainer on the right says both: Describe the context keys that will be updated by your action and if you need more than one condition to be met, you can use '&&' etc etc..
Can anyone explain this feature functionality better? thanks
I also had confusions in understanding the context part, but later figured it out.
Let me try to explain the way I understood.
In a story you want some actions to be executed and also you want your actions to return some result or rather I would say, you want some variables to be set with some value within your action that you will use in the next step of your conversation in wit.ai. Those variables can be defined in wit.ai as context keys.
Below is an example:
I have a credit card and I want to report lost card using bot. I say I lost my credit card and give the bot required information for it to fetch my card details, then it will call an action BlockCard. As a result of execution, I need the name, last 4 digits of the card and reference number for the raised complaint. These 3 variables need to be filled in while the action BlockCard runs. These are declared in wit.ai as context keys with '&&'. I would use these variables in the further conversation.
Note: You need to make sure that the name of context keys and name of the actions declared in wit.ai and the names used in your code are same.
Have a look at wit story:

I am trying to add a formal parameter in the FORM and PERFORM in an existing code, as I will be need it the extra parameter in a new function that I have to call. The idea is that when executing the new code it keeps showing the error: Different parameter count in FORM and PERFORM (routine: CM_SHOW_CRC, number of formal parameters: 2, number of actual parameters: 3).
The code that I have for the form part is as follows:
FORM cm_show_crc
USING
civ_matnr TYPE matnr
civ_charg TYPE charg_d
civ_werks TYPE werks_d. "The parameter that I added
And the perform code is:
PERFORM cm_show_crc
USING
pis_sdow_alv-matnr
pis_sdow_alv-charg
pis_sdow_alv-werks. "The parameter that I added
The table pis_sdow_alv is type of a structure that also includes the variable WERK(Component type WERKS_D)
Before adding the new parameter WERK the code was working fine.
May anyone know what the problem in this part of the code may be?
There was also another similar question in: Different number of parameters in FORM and PERFORM, however I am not using the syntax CHANGING in my code, as it was also not used prior.
Please do tell me if you need additional information.
Thank you all in advance!
This problem can occur when FORM and PERFORM are in different includes and you only activate one but not the other.
When you activate an include, then it is checked against the active version of all other repository objects it depends on. Not the saved version. This can lead to an annoying catch-22 situation. You can not activate A because it does not match the previous version of B, and you can not activate B because it does not match the previous version of A.
The solution to this conundrum is to activate both objects together. When you activate something in SE80 and you have multiple inactive objects, you get a window where you can select multiple objects to activate together:
In Eclipse, you get a similar list by clicking on the "activate multiple" button:
I am doing a simulation of a production line, which is built through Excel.
Now there is one, which needs free setting of worker shifts for each machine, three shifts in total.
My idea is to create three different Schedules, representing each of the three shifts, and then in the ResourcePool, use the If statement to set up the use of each shift. As shown in the picture enter image description here
But it didn't work. If it is possable, Could you please tell me if there is something wrong with the Java statement or the idea is wrong.
If possible, could you please tell me how to set multiple schedules in ResourcePool?
Additions to the question：
The model is to do the evaluation of the production system and the shift of the workers is an important evaluation parameter. What I want to do is to enter the shift of the workers directly in the Excel sheet and ResourcePool recognizes and uses the corresponding Schedule.
I tried to generate the corresponding Schedule by code, but the Schedule of Resourcepool cannot be set dynamically. So I would like to try to manually input multiple Schedules into the model and then set the corresponding Schedule in ResourcePool by If statement like the image.
Thanks in advance
The first thing you need to know is that the location where you placed the code is a static parameter, thus it is only evaluated once, when the object is created and not checked continuously.
This is indicated by the little popup when you hover over the button that change the entry field from code to value
If it was dynamic it would state Dynamic Value instead of Static Value
Secondly, inside that field you must use a ternary operator, not an if statement, so that the result of the formula is a scheduled object, else you will get a "misplaced construct(s)" error
If you changed the code to
v_Shift == "Shift1" ?
s_Shift1 : v_Shift == "Shift2" ? s_Shift2 : s_Shift3
It will work BUT:
It will only be evaluated when the object is created and not again
Rather not use == on Strings, always use .equals(), on Strings it might work, and sometimes it might not. You can do some research as to why ;-)
Solution: You will have to use a function to change the schedule of the resource pool. Call this function whenever the v_Shift variable changes

I made MDG technology extending Object metatype. I have a shape script for my stereotype working well. I need to print several predefined run-state parameters for element. Is it possible to access to run-state params within Shape ?
As Geert already commented there is no direct way to get the runstate variables from an object. You might send a feature request to Sparx. But I'm pretty sure you can't hold your breath long enough to see it in time (if at all).
So if you really need the runstate in the script the only way is to use an add-in. It's actually not too difficult to create one and Geert has a nice intro how to create it in 10 minutes. In your shape script you can print a string restult returned from an operation like
print("#addin:myAddIn,pFunc1#")
where myAddIn is the name of the registered operation and pFunc1 is a parameter you pass to it. In order to control the script flow you can use
hasproperty('addin:myAddIn,pFunc2','1')
which evaluates the returned string to match or not match the string 1.
I once got that to work with no too much hassle. But until now I never had the real need to use it somewhere in production. Know that the addin is called from the interpreted script for each shaped element on the diagram and might (dramatically) affect rendering times.
The new Google Drive Android API has 2 types of string IDs available, the 'resource' ID and the 'encoded' ID.
'encoded' id from DriveId.encodeToString()
"DriveId:CAESHDBCMW1RVVcyYUZKZmRhakIzMDBVbXMYjAUgssy8yYFRTTNKRU55"
'resource' id from DriveId.getResourceId()
"UW2aFJfdajB3M3JENy00Ums0B1mQ"
In the process I end-up with a string that can contain any one of them (result of some timing issues). My question is:
If I need to 'parse' the string in order to identify the type, is there a characteristic I can rely on? For instance:
'encoded' id will always start with 'DriveId:' substring
'resource' id will have some length limit
can I abuse error return from 'decodeFromString()'?
or should I form (pre-pend) the string container with my own tag? What could be the minimal 'safe' tag (i.e. what will never appear in the beginning of these ids) ?
Please point me in the right direction so I don't have to re-do it with the next release.
I have run into yet another issue that should be mentioned here so others don't waste time falling into the same pit. The 'resourceID' can be ported and will remain unique for the object it identifies, where 'encodedID' has only 'device' scope. Means that you CAN'T transfer 'encodedID' to another device (with the same account) and try to retrieve file/folder with it. So I assume it is unique to a Google Play Services instance.
Please do not rely on any formatting of either ID type. This are subject to change without notice.
If you need to use both, and track the differences between them you should have your own method of doing so within your app.
Really, you should probably always just store the encoded ID since this one is always guaranteed to present, and if it contains a resourceId, its easy to get back out.
First, i admit all the things i will ask are about our homework but i assure you i am not asking without struggling at least two hours.
Description: We are supposed to add a field called max_cpu_percent to task_struct data type and manipulate process scheduling algorithm so that processes can not use an higher percentage of the cpu.
for example if i set max_cpu_percent field as 20 for the process firefox, firefox will not be able to use more than 20% of the cpu.
We wrote a system call to set max_cpu_percent field. Now we need to see if the system call works or not but we could not get the value of the max_cpu_percent field from a user-spaced program.
Can we do this? and how?
We tried proc/pid/ etc can we get the value using this util?
By the way, We may add additional questions here if we could not get rid of something else
Thanks All
Solution:
The reason was we did not modify the code block writing the output to the proc queries.
There are some methods in array.c file (fs/proc/array.c) we modified the function so that also print the newly added fields value. kernel is now compiling we'll see the result after about an hour =)
It Worked...
(If you simply extended getrlimit/setrlimit, then you'd be done by now…)
There's already a mechanism where similar parts of task_struct are exposed: /proc/$PID/stat (and /proc/$PID/$TID/stat). Look for functions proc_tgid_stat and proc_tid_stat. You can add new fields to the ends of these files.
