Is skipping “accept” where type is known, a valid optimization for the Visitor pattern?
java,visitor,visitor-pattern,code-design
Visitor is just a complicated scaffold to implement double-dispatch on languages like Java. When you deal with leaf types, you don't need double-dispatch; the runtime type is known at the compile time. Dispatch a leaf type directly is not only an optimization, it's more out of principle. Of course, the...
Requiring same module in multiple files
javascript,node.js,express,code-design,code-structure
From the node.js documentation: Modules are cached after the first time they are loaded. This means (among other things) that every call to require('foo') will get exactly the same object returned, if it would resolve to the same file. Multiple calls to require('foo') may not cause the module code to...
prevent unassigned objects, any reason this is a bad design consideration?
To keep this simplified in coding, I put a "ShowDialog()" call at the end of the constructor of the form being displayed. That sounds like an ugly design to me, personally. Constructors are designed to return a usable object - and ideally that's all they should do. I would...
Design pattern for incremental code
java,design-patterns,code-design
I think this is called pipeline: http://en.wikipedia.org/wiki/Pipeline_%28software%29 This pattern is used for algorithms in which data flows through a sequence of tasks or stages. You can search for a library that does this( http://code.google.com/p/pipelinepattern ) or try your own java implementation Basically you have all you objects in a list...
