To illustrate the problem we use a simple case: there are two aggregates - Lamp and Socket . The following business rule always must be enforced: Neither a Lamp nor a Socket can be connected more than once at the same time. To provide an appropriate command we conceive a Connector -service with the Connect(Lamp, Socket) -method to plug them. Because we want to comply to the rule that one transaction should involve only one aggregate, it's not advisable to set the association on both aggregates in the Connect -transaction. So we need an intermediate aggregate which symbolizes the Connection

I am using the Raphael Javascript library to do some rudimentary drawing for a web page. I am just drawing some lines that radiate out from a point. In Chrome, Firefox, and Opera, these lines are subject to the size of the SVG canvas. This is the desired behaviour, because I want to draw a ray as long as I want but I do not want it to affect the size of the page. If I draw a 5000px wide box, only the part inside the canvas will be visible. However, Internet Explorer (surprise surprise) completely ignores the size and bounds of the canvas and accommodates whatever is drawn. So if I draw a

I need extract double Male-Cat : a = "Male-Cat Male-Cat Male-Cat-Female" b = re.findall(r'(?:\s|^)Male-Cat(?:\s|$)', a) print (b) ['Male-Cat '] c = re.findall(r'\bMale-Cat\b', a) print (c) ['Male-Cat', 'Male-Cat', 'Male-Cat'] I need extract tree times Male-Cat : a = "Male-Cat Male-Cat Male-Cat" b = re.findall(r'(?:\s|^)Male-Cat(?:\s|$)', a) print (b) ['Male-Cat ', ' Male-Cat'] c = re.findall(r'\bMale-Cat\b', a) print (c) ['Male-Cat', 'Male-Cat', 'Male-Cat'] Another strings which are parsed correctly by first way: a = 'Male-Cat Female-Cat Male-Cat-Female Male-Cat' a = 'Male-Cat-Female' a =

I have a customers HTTP call working using the standard apache classes but I am trying to create a custom Volley class to handle this. Here is the code for standard call: HttpURLConnection conn = (HttpURLConnection) new URL(strUrl).openConnection(); conn.setDoOutput(true); conn.setDoInput(true); conn.setConnectTimeout(30000); conn.setUseCaches(true); conn.setRequestMethod("POST"); conn.setRequestProperty("Authorization", "Token " + m_apiKey); conn.setRequestProperty("Accept", "text/plain , application/json"); conn.setRequestProperty("Connection", "Keep-Alive"); conn.setRequestProperty("Content

What are non-word boundary in regex (\B), compared to word-boundary? A word boundary ( \b ) is a zero width match that can match: Between a word character ( \w ) and a non-word character ( \W ) or Between a word character and the start or end of the string. In Javascript the definition of \w is [A-Za-z0-9_] and \W is anything else. The negated version of \b , written \B , is a zero width match where the above does not hold. Therefore it can match: Between two word characters. Between two non-word characters. Between a non-word character and the start or end of the string. The empty string. For
