The framework defines an interface to branching "methods" that compete to make fractional solutions more integral.
The procedural part defines a generic interface between interactive digital applications and the terminals on which those applications are executed.
It defines an interface to this internal model, rather than the internal model itself.
We define an interface, which will enforce implementation of declared methods.
Define an interface specifying requested behavior of serviced objects.
So we create class, whose instances offer that requested functionality and which defines an interface, which serviced objects must implement.
So we define an interface, which classes with desired functionality must implement.
For example, an abstract class can define an interface without providing implementation.
However, each module will define an interface to its surrounding modules.
When we define an interface, PayloadList, that associates an optional value of generic type P with each element.
