I want to add a method to the Graph class of the JUNG library using Eclipse. How would I do this?
I have the JUNG working correctly as a reference library by following this answer: https://stackoverflow.com/a/5618076/1949665
1) You have access to the source:
Simply add your method
2) You could extend the class and add the method in our extending class
3) Write a Util class with a static method implementing your method than simply uses the original class.
Your comment above implies that you want to be able to find cliques in a graph. (I didn't see the original question before you edited it.)
If so, it doesn't need to be a method on Graph itself, it just needs to accept a Graph as an argument. Graph is a type like List or Map, it should not have a method for every kind of algorithm you might want to use on a graph.

First of all check this post, we discourage screenshots of code and/or errors so please post code in future instead of screenshot.
From screenshot on is non-static data member of playbutton class. You can't use non-static data member in all class.
You need an object of playbutton, if you want to access any non-static data member.
playbutton x=new playbutton();
x.on=true;
I'll recommend you to follow naming conventions in java for better coding experience.
I'm searching quite a while now but I cannot find anything. Is there a possibility in Swift to supply an own implementation of a class or a method without touching the library. Subclassing would not be an option.
As Example from ios charts (https://github.com/danielgindi/ios-charts) I only want to replace the LineScatterCandleRadarChartRenderer class (https://github.com/danielgindi/ios-charts/blob/master/Charts/Classes/Renderers/LineScatterCandleRadarChartRenderer.swift) or the single method it is implementing. It is a subclass of a subclass of a subclass used somewhere in the library when plotting the chart.
What would be the best practice to do this?
I found an answer for python: Cast base class to derived class python (or more pythonic way of extending classes)
Is it possible to write ObjectScript method, which will create new class in namespace and compile it? I mean programmatically create new class and store it. If so, can I edit this class using ObjectScript later(and recompile)?
Reason: I have class structure defined in string variable and I need to add new class to namespace according this string.
Nothing is impossible. Everything in Caché can be created programmatically. And, Classes is not a execution. There are at least two ways to do it:
simple SQL Query CREATE TABLE, will create a class.
and as you already mentioned ObjectScript Code, which can do this.
All of definition of any classes defined in other classes. Which you can find in package %Dictionary.
The class itself defined in %Dictionary.ClassDefinition. Which have some properties, for defining any parts of classes. So, this is a simple code which create some class, with one property.
set clsDef=##class(%Dictionary.ClassDefinition).%New()
set clsDef.Name="package.classname"
set clsDef.Super="%Persistent"
set propDef=##class(%Dictionary.PropertyDefinition).%New()
set propDef.Name="SomeProperty"
set propDef.Type="%String"
do clsDef.Properties.Insert(propDef)
do clsDef.%Save()
And in latest versions, there is one more way for create/change class. If you have text of class as you can see it in Studio. Then, you can load it in Caché, with class %Compiler.UDL.TextServices
Yes, it is. You likely want to make use of %Dictionary.ClassDefinition and the related %Dictionary.*Definition classes (especially %Dictionary.PropertyDefinition, %Dictionary.MethodDefinition and %Dictionary.IndexDefinition) to create and/or modify your class. Provided your string contains some reasonable representation of the data, you should be able to create the class this way.
The actual class documentation is available at http://docs.intersystems.com/cache20141/csp/documatic/%25CSP.Documatic.cls?CLASSNAME=%25Dictionary.ClassDefinition
You can then compile the class by calling $system.OBJ.Compile("YourPackage.YourClass","ck").
(Note: If your string contains the exported XML definition of the class, you could also write the XML representation to a stream and then call $system.OBJ.LoadStream() to import the XML definition. I would only recommend this if you have an exported class definition to start with.)
Is there a quick way to count the number of methods in a MATLAB class ?
obj = myClassName()
Is there a way to get the number of methods inside this class?
Yes! At least in MatlabR2014b you can use methods
example:
methods('SURFPoints')
or
methods('myClassName')
Probably you would be able to find it with a quick google but you mix your terminology a bit. myClassName() is a class, and all the functions that are specific of this class and are "inside" it are called methods. Do not call method to a class! There is nothing like "number of functions used in a method" (well, there is but its definitely not what you are looking for).
You can use:
a = ?MyClassName;
numMethods = numel(a.MethodList);
Here a is a metaclass object that contains all the details of the class MyClassName, such as its package, properties, methods, events etc.
So far this one seems to go against the grain of Php OOP. Let me explain further with an example.
class main has a function called get($name), what I would like get to do is based on the value of $name, (e.g. 'path/file') would find the corresponding file and include it, so the class in path/file can be used.
My goal with this and the reason I want to do this, is when I call $main->get('path/file'), I'd like an object returned of the class within the file, so far the only solution I can figure out is to use
include($main->get('path/file'));
And within said file would be an object defined outside the class body within path/file.php, but that doesn't really solve the issue as it limits me to using the object defined in that file, and I can only use this include call outside a class body. Does anyone have any ideas on how this can be approached?
