I have a scenario where i want to store data to HashMap after processing in tMap component.
my flow is as follow :
tFileInputExcel------>tMap------>tJavaRow/tJavaFlex
In tJavaRow, i want to store all my data into a HashMap.
Any help on this.
Additionally to Philipps answer, I would like to add that you could use the tHashMap components. Usually those are deactivated when Talend is installed and you need to activate them first.
Then it is very easy using them, just add the components as you are used to do. You would save creating code.
It's not difficult to do this but it'll be less obvious to the "reader" of the code than the usage of the components.
For readability I'd recommend a tJavaFlex component over the tJavaRow. Assuming the Flow "toHashMap" exits your tMap with the fields "myKey" and "myValue", the code in the tJavaFlex would look like this:
Start code:
HashMap myAwesomeMap = new HashMap<>();
Main code:
myAwesomeMap.put(toHashMap.myKey, toHashMap.myValue);
End code:
/*
whatever you want to do with the aggregated data. You'll probably want to save it to the globalMap in any case.
*/
globalMap.put("myAwesomeMap", myAwesomeMap);

I have this piece of code in JSON editor of Watson:
"context": {
"array": "<? entities['spare_part'].![literal] ?>",
"array_size": "<?$array.size() ?>"
When the input of the user, for example, is "Hello, I need a valve, and the part number of the valve is 1234", the size of the array ends up being 2 since the user mentions the word "valve" twice in his input. Some nodes are being executed depending on size of the array. For instance if the size of the array is 1, some nodes will be ignored because they are only executed only if the size of the array is 2.
I want the array to store only the inputs with different values, which is basically I don`t want the array to store the values of the same type, in my case 2 valves. If it is possible somehow please show me a way.
All that can be done, but the best approach depends on the overall system architecture. Remember that Watson Assistant is a conversation service, not a data processing platform...
You can process JSON in either Watson Assistant directly using the built-in methods and SpEL, see these links to get started:
- https://console.bluemix.net/docs/services/conversation/expression-language.html#expressions-for-accessing-objects
- http://docs.spring.io/spring/docs/current/spring-framework-reference/html/expressions.html

That would require some coding within the dialog nodes. It could be ok. What I would recommend is to either process in your app that drives the dialog (you need that app anyway) or to code up small server actions to transform data.
If it is the word you are looking for, you can use contextual entities to train for this.
As an example I created the following intent (along with general intents from catalog).
For each example I highlighted the "valve" word that is the one I am interested in, and added to the entity.
Now when I test it I get the following.
All this was done in a couple of minutes. For production level you may want to add more examples, or think about how you want to annotate.
I am trying to create a Hierarchical block using the GNURadio Companion GUI. Answers I've found in other posts say to select the blocks you want to incorporate, then go to More -> Create Hier. Then a new screen is supposed to appear. However, doing "Create Hier" with any combinations of blocks selected seems to do nothing.
Am I doing something wrong, or is there a problem with my GRC?
It's very simple. You just start with a new flow graph in GRC, and use Pad Sources as input, and Pad Sinks as output.
If you want to let the user configure something, use a Parameter GRC block.
You must set the Generate Options in the Options block to Hier Block, and set a sensible ID there, too – don't stick with top_block, but use something (without spaces or -; it needs to work as a python name) that won't conflict with something else.
Here's an example:
You can then Generate button (or press [F5]), and then, after you've done a rescan of your block library with the refresh button you can find (and use) your new block in the Block Category you specified.
I am working on a code "maintenance" idea where I would like to populate a global when routines are accessed and by who. I can pull the current routine name using $t(+0) or $ZNAME, but what about the current tag and/or line offset? Is there a way so I can put a standard line in the routines I want to track?
Rob, you can get these information from $STACK.
If you call your own tracking function, you get the calling stack info like this:
W $STACK($STACK(-1)-1,"PLACE")
zExecute+2^%Studio.General.1 +1
Take a look at the Caché ObjectScript Reference for $STACK for detailed description and examples.
Rob!
Maybe you just turn on Audit? It gathers logs for different users activities in InterSystems Caché database. See the documentation on Caché Audit.
Also, see this solution which will help you to examine analytics in DeepSee regarding Audit entries.
You can find the routine that's calling your label, by the following ClassMethod.
write ##class(%SYSTEM.Process).CallingRoutine()
As well as the database which is calling your label.
write ##class(%SYSTEM.Process).CallingDatabase()
I'm trying to create a pair of forms in a (scaffolded) Yesod setup where:
form 1 allows a user to choose a file. That file is parsed into a set of records and then the user is given
form 2 which has a selectFieldList for choosing a record.
So I have
form2::[(Text,Record)]->Form Record
form2 recordInfo = ...
which is fine for when I generate it (generateFormPost $ form2 recordInfo) . But to process the result, I will be in a different handler and I no longer have the list of (Text,Record) pairs to give to the form2 function in order to execute runFormPost (runFormPost $ form2 ??). So I can't get the data from the form.
I realize this is a consequence of the statelessness of the RESTful web. And I realize there are some ways out of this. I could use persistent and hand some sort of key to the handler so it knows where to get the (Text,Record) data. Or I could use session somehow? Or cookies?
This web stuff is new to me so before I launch in a silly direction, I was wondering if there is a simple answer I am missing and, if not, what is the "right" way to handle forms that depend on dynamic data in this way?
So new to MarkLogic am stuck and not finding the documentation of use. I know what i need to do, just do not know how to do it.
I have a keyvalue? search on my REST server which returns ML's standard search results and XML snippet. I want to create my own custom search result which will output a title element for my XML files.
I am aware that i need to create an XSLT transformation document and upload that to the server but do not know how to target ML's search function or how to write this out.
I have basic knowledge of XSLT, if i just created something that targets each files title using xPath will this work, or does ML require use of their custom functions?
I know its a bit broad, but hopefully someone can point steer me.
Sounds like you are talking about the GET /v1/keyvalue endpoint of MarkLogic REST API. Unfortunately that does not allow you to choose a transform. You can probably use GET /v1/search with a transform param instead though, using a structured query for an element value query. The docs contain a good syntax reference on that.
Docs on creating and managing transforms can be found here:
http://docs.marklogic.com/guide/rest-dev/transforms#chapter
HTH!
You can use extract-metadata in your search options with search:search or the /v1/search/ REST API endpoint to include the title element in a metadata element or JSON property in your results:
import module namespace search = "http://marklogic.com/appservices/search"
at "/MarkLogic/appservices/search/search.xqy";
search:search(
"my query string",
<options xmlns="http://marklogic.com/appservices/search">
<extract-metadata>
<qname elem-ns="" elem-name="title"/>
</extract-metadata>
</options>)
If you need more flexibility, you specify a custom snippet implementation or a results decorator function in your search options.
Is this key-value or full text? For key-value you could use XPath. Any XPath that starts with / or // or fn:collection() or fn:doc() will search the entire database. You can search specific document(s) or collection(s) too.
For full text you'd probably want to use https://docs.marklogic.com/search:search - or possibly https://docs.marklogic.com/cts:search for really low-level control.
There's some example code using search:search from XSL at https://github.com/marklogic/RunDMC which might help. It doesn't use the REST API: it's a traditional form-submit web page. But the view/search.xsl code might give you some idea how to call the search API from XSLT.
That RunDMC code might also help you if you need to call XSL from XQuery: take a look at controller/transform.xqy.
