Title: Functional Adaptive Programming
Abstract:
The development of complex software requires the implementation of
operations over recursively defined data structures. Complex data
structures lead to an increase of code dealing with structure access
and navigation. This `boilerplate' code in turn makes programs
tedious to develop, difficult to maintain, prone to errors, and
separates important functionality, all of which result in the loss of
clarity. Generic (or polytypic) programming and higher order
functions can resolve some of these issues, but are usually too
general to be practically useful for large collections of data types.
This dissertation proposes a new approach to developing
structure-based functions and describes an implementation of these
ideas in Java, called DemeterF. Our approach uses function-objects
over an adaptive traversal to implement deep, fold-like functions over
data structures. Function-classes/objects provide a useful and
flexible form of generic programming that adapts to different data
structures using a type-based multiple dispatch. We model DemeterF
with function sets and structural recursion, and give it a type system
that shows our function-objects, multiple dispatch, and traversals can
be checked for safety. In order to show that our approach is
efficient we present the results of several performance tests
comparing DemeterF to hand-written methods and visitor implementations
in Java.
