I am trying to build Esper EPL statements in Java.
I use the com.espertech.esper.client.soda lib for this, but I can't find
a tutorial to help me.
The PatternExpressions are the only part that I need as of now.
As an example let's use the EPL:
every a=Event((a).getEventTypeCode()='E00001')
So he should trigger on every Event with the event type code E00001, we get the code by
calling the getEventTypeCode Method.
How do I project this to SOM?
With:
PatternExpr pattern = Patterns.everyFilter("Event","a");
I only get:
every a=Event
(of course)
I know there is a class called "MethodInvocationStream" but I don't know how to use it.
And I cannot find examples for its use.
Thanks to user650839 I found out how to add Methods via SOM.
Here is a simple EPL as an SOM Object: http://imgur.com/SDrTsa7
One source of info is the javadoc.
You could simply do the reverse and compile EPL text to a model object and inspect that. Use "epAdmin.compileEPL", the output is the same object you want to build via API.\

In this link from MDN, it explains how to write a unit test for developing an addon for firefox. However, there are several segments that I don't understand and didn't find any useful result after searching google.
The first one, the following is a paragraph quoted from above link:
In a web page, you can perform Base64 encoding and decoding using the
btoa() and atob() functions. Unfortunately these functions are
attached to the window object: since this object is not available in
your main add-on code, atob() and btoa() aren't available either. So
we'll create a base64 module to expose these functions from the
platform (see Creating Reusable Modules).
What does "the platform" in the above paragraph mean? the "Services.jsm"?
Also in the following code:
const { atob, btoa } = require("resource://gre/modules/Services.jsm");
this makes atob and btoa as one of the Services that is available for other class? or make (constant variables)atob and btoa both reference to the Services.jsm?
The Second one:
what are these two lines of code do?
exports.atob = a => atob(a);
exports.btoa = b => btoa(b);
I understand the part
exports.atob
which enables atob function to be available from other classes outside the "base64.js".
but what does the following mean?
= a => atob(a);
I didn't find that javascript has "=>" operator!
From my understaning, the reason we create a base64.js is because atob and btoa can only be called if we have the window object. Therefore we can use Services.jsm to get a reference of the window object?
For "platform" in the paragraph you quoted they mean the set of functions which is not strictly Firefox browser code but rather implements basic, share functionalities. This usually lives in toolkit/modules in the mozilla-central repository. Services.jsm lives there as well so yes, that's part of the platform. Moreover, atob and btoa are both imported from Services.jsm.
The arrow => in exports.atob = a => atob(a); defines what's called an arrow function: it's a new, shorter syntax to define functions in JavaScript. This SO answer has many useful informations about it.
From my understanding, the reason we create a base64.js is because atob and btoa can only be called if we have the window object. Therefore we can use Services.jsm to get a reference of the window object?
That's almost correct: you need to export the function from the underlying platform as you don't have a window object there. If you had a window object, you would have just done window.atob or something like that. That call would have still called the same function you imported from Services.jsm.
So you're not using Services.jsm to get a reference to the window object, but rather directly importing the needed functions so that you don't need to have a window object.
I am working through the ruby evernote-thrift API and sandbox.
I am experiencing some issues interpreting the docs; I am trying to retrieve the subject line from all the notes inside a particular notebook.
To get the name of the notebook I call
notebooks = noteStore.listNotebooks(authToken) and then run .each on notebooks. According to the docs there is a struct object called noteList but I can’t figure out how to use it.
this is the link to the docs area I am trying to leverage http://www.rubydoc.info/gems/evernote-thrift/Evernote/EDAM/NoteStore/NoteList#struct_fields-instance_method
my attempt, is as follows, but its not returning anything. unfortunately im not familiar with structs at all.
notebooks = noteStore.listNotebooks(authToken)
notebooks.each do |notebook|
next if notebook.name != 'First Notebook'
notes = notebook.noteList
noteList.each do |note|
puts note
end
end
i am getting a no method error... which makese sense because its a struct I just dont know how to leverage it...
undefined method `noteList' for <Evernote::EDAM::Type::Notebook:0x007fb2041683f8> (NoMethodError)
The generated docs for our Ruby SDK are confusing (sorry!), but I find the general docs to be much clearer: https://dev.evernote.com/doc/reference/.
As you can see in https://dev.evernote.com/doc/reference/Types.html#Struct_Notebook, the Notebook object does not have an attribute called noteList. There is a struct called NoteList, but that was what the removed NoteStore.findNotes returned.
The procedure for getting the titles/subjects of the notes in a notebook is to get the Notebook (which you have done), then pass the notebook's guid into NoteStore.findNotesMetadata (https://dev.evernote.com/doc/reference/NoteStore.html#Fn_NoteStore_findNotesMetadata). This returns a NotesMetadataList which has a notes attribute which is a list of NoteMetadata. This struct has metadata like title and GUID but not the body. If you want the full information, you would pass the GUID into NoteStore.getNote (https://dev.evernote.com/doc/reference/NoteStore.html#Fn_NoteStore_getNote).
That API is one of the least Ruby things I've ever seen. You have my condolences for trying to trudge through that :)
From the API docs, all I'm seeing that hangs off of that Evernote::EDAM::Type::Notebook class are #struct_fields and #validate, as far as instance methods go. Perhaps that struct_fields has what you're looking for?
If that doesn't lead you anywhere, I'd suggest doing using something like Pry to help you troubleshoot the error. I'd put a binding.pry statement on the second line and then explore the notebooks objects from there.
I'm trying to write a simple Cocoa App to scan some documents from my USB-scanner. I use it the same way as this example of apple: https://developer.apple.com/library/mac/samplecode/ScannerBrowser/Listings/AppController_m.html
The 'deviceBrowser:didAddDevice...' method is called. There I set the scanners delegate to self (like in the example), but the methods 'deviceDidBecomeReady' or 'scannerDeviceDidBecomeAvailable' are never called.
Is there anything I have forgotten?
Here is the code:

Oh... reading the .h-files of the frameworks should still be the first option. The order was wrong and I forgot didOpenSessionWithError.
Here is the working code:

How do I troubleshoot the following error being thrown by a Microsoft AJAX JavaScript framework method? It is an automatically generated line of JavaScript from a custom User Control in a Web Forms App (Sitefinity 5 CMS)
Error Message:
Unable to get property 'FancyBlockDesigner' of undefined or null reference
Here is the JavaScript that is throwing the error:
Sys.Application.add_init(function() {
$create(SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner, null, null, {"Editor":"propertyEditor_ctl00_ctl00_ctl00_ctl00_ctl00_Editor","propertyEditor":"propertyEditor"}, $get("propertyEditor_ctl00_ctl00_ctl00"));
});
Rather than discuss the ascx and cs files that try to abstract this detail away from me, I want to know what this error means. If I understand the detail, the abstraction might make more sense.
"$create" function in ASP.NET Ajax creates an instance of JavaScript class. Microsoft had their own opinion on how to make JavaScript object orientated and as time had shown, their approach wasn't exactly perfect.
Anyhow, to try to explain what is happening, let me give a bit of an overview oh how it works. We start by a server side control which implements IScriptControl interface which mandates two members: GetScriptDescriptors and GetScriptReferences. The second one is pretty straightforward - it lets you register references to all JavaScript files that you control will require. The GetScriptDescriptors, on the other hand, let's you define all the instances of JavaScript classes you want to use as well as it lets you set their properties - initialize them, if you will.
What the autogenerated JavaScript code you've pasted says is basically that you have defined in GetScriptDescriptors that you will need an instance of type "SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner" where you want Editor property to be initialized. This code will go and look for a JavaScript constructor that looks like this:
function SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner(element) {
}
that most probably also has a prototype defined, something like:
SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner.prototype = {
}
Now, since the error you have posted states: "Unable to get property 'FancyBlockDesigner' of undefined or null reference", most probably one of the following is the problem:
You have not included the JavaScript file which contains the class (constructor + prototype) that I've talked about above
You have forgot to add the "FancyBlockDesigner" to the constructor (it seems that you do have other object, perhaps through MS Ajax namespaces - "SitefinityWebApp.Esd.TheLab"
You have not registerd the "SampleHtmlEditor" namespace. Make sure at the top of your JS file you have this: Type.registerNamespace("SitefinityWebApp.Esd.TheLab.SampleHtmlEditor");
So, short story long, the function with name "SitefinityWebApp.Esd.TheLab.SampleHtmlEditor.FancyBlockDesigner" cannot be found.
Hope this helps,

Is there a way to use a wildcard inside an assertion in a XPath test with SoapUI?
I took a look at SoapUI's documentation and they say you can do something like this
<path1>
<path2>*</path2>
</path1>
I checked the 'Allow Wildcards' checkbox.
My question is : I want to assert my date starts with 2012-08-22 but i dont care about the minutes and seconds. I guess my the expression should be something like 2012-08-22* but it doesn't work.
What you are doing sounds like it should work. Here is a quick example i cooked up using a rest service from http://www.geonames.org/export/web-services.html#timezone. I'm using the demo they have supplied
http://api.geonames.org/timezone?lat=47.01&lng=10.2&username=demo
output is
<geonames>
<timezone tzversion="tzdata2012c">
<countryCode>AT</countryCode>
<countryName>Austria</countryName>
<lat>47.01</lat>
<lng>10.2</lng>
<timezoneId>Europe/Vienna</timezoneId>
<dstOffset>2.0</dstOffset>
<gmtOffset>1.0</gmtOffset>
<rawOffset>1.0</rawOffset>
<time>2012-07-25 04:39</time>
<sunrise>2012-07-25 05:50</sunrise>
<sunset>2012-07-25 21:00</sunset>
</timezone>
</geonames>
If you do an xpath match on the result and use the select from current button you get
//geonames/timezone/time
2012-07-25 04:39
If you update this to
//geonames/timezone/time
2012-07-25*
this will work fine and when updating the rest request with a new lat and lng the assertion will still pass since it is not checking the time. If this doesn't help, please supply your full assertion and maybe i could help more.
*note: for soap requests, make sure to declare the namespace and then use the proper format
//ns1:message
It will be sort of a pain, but here is what you can do:
1) Figure out an Xpath 'base' using the assertion tab (sounds like you are here already). I used this public site to test against: http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl
I used the CornerPoints method with 'hawaii' as the single param.
I created this 'base' xpath:
declare namespace ns1='http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl';
declare namespace SOAP-ENC='http://schemas.xmlsoap.org/soap/encoding/';
declare namespace SOAP-ENV='http://schemas.xmlsoap.org/soap/envelope/';
/SOAP-ENV:Envelope/SOAP-ENV:Body/ns1:CornerPointsResponse/listLatLonOut
(it will write the declare statements for you if you click declare)
(which you can test out in the assertions window)
2) Create a Properties step
3) Create a Property transfer step
4) Create a groovy script
5) add a property... i called mine misc
6) add a transfer step
* transfer from the CornerPoints - Request 1 --- Response
* paste the Xpath stuff in the box under the 'transfer from'
* Transfer to your property
(You can test with the little play button)
7) Add something like this to your groovy script:
def x = context.expand( '${Properties#misc}' )
def parts = x.tokenize(',')
for (def part in parts)
{
log.info(part)
if (part.startsWith("-153"))
log.info("good")
}
In the groovy step you can do anything you need to get at your (partial) data. The sample code I added gets lat/lons out of a long line wrapped in CDATA and then checks for just the starting part of some of the data.. just an example.
Remember that you can use groovy and java string methods:
