class JavaUtilCollection extends GenericInterface { JavaUtilCollection() { this.hasQualifiedName("java.util", "Collection") } } To make sure we have not mistyped anything, we can run a simple test query: from JavaUtilCollection juc select juc This query should return precisely one result....

In C++, templates provide one of the vehicles of generic programming - class templates provide support for type-safe generic containers, while standalone function templates represent generic algorithms. Hence templates in C++ are not strictly tied to the object oriented model - in fact, C++ ...

Functor - Function that can be manipulated as an object, or an object representing a single, generic function. Graph - General purpose graph APIs and algorithms. I18n - Adds the feature of localized message bundles that consist of one or many localized texts that belong together. Id - Id is...
We can define our own classes and interfaces with generics type. A generic type is a class or interface that is parameterized over types. We use angle brackets (<>) to specify the type parameter. To understand the benefit, lets say we have a simple class as: ...
