I have been working with C++ for a few years now and have got good theoretical knowledge on the matter (I think).
I\'m working on a project and it\'s in a stage that I don\'t know what\'s wrong. Here\'s the simplified version:
I\'m doing some work with Genetic Algorithms and want to write my own GA classes. Since a GA can have different ways of doing selection, mutation, cross-over, generating an initial population, calcula
I just realized how useful the little on-function can be. Ex: orderByLength = sortBy (compare `on` length)
I\'m trying to create a type that has multiple type para开发者_运维问答meters.I know how to make a type with one parameter:
Long switch statments are often frowned upon. The solution is to use polymorphism. However what if the thing I\'m switching on is not a type code? What I would like to do is replace the switch stateme
I have two objects: public class ParentObject { // some basic bean info } public class ChildObject extends ParentObject {
Ok, the context is some serialization / deserialization code that will parse a byte stream into an \'object\' representation that\'s easier to work with (and vice-versa).
I have a couple of small classes to represent parts in a search filter. If the searched value equals NonValue the filter is supposed to do nothing. This is defined in a Base Class:
Consider the following example code: class Foo { }; class Bar : public Foo { }; class FooCollection { protected:
