2nd Edition
by Primož Gabrijelčič
Discover algorithm performance,
high- and low-level optimizations, and the internal behavior of
programs written in the Delphi language
Key Features
- Discover external programming libraries that will speed up your programming and code
- Learn to integrate external libraries into Delphi programs
- Build fast Delphi applications using concurrency, parallel programming, and memory management
Book Description
Performance
matters! Users hate to use programs that are not responsive to
interactions or run too slow to be useful. While becoming a programmer
is simple enough, you require dedication and hard work to achieve an
advanced level of programming proficiency where you know how to write
fast code.
This book begins by
helping you explore algorithms and algorithmic complexity and continues
by describing tools that can help you find slow parts of your code.
Subsequent chapters will provide you with practical ideas about
optimizing code by doing less work or doing it in a smarter way. The
book also teaches you how to use optimized data structures from the
Spring4D library, along with exploring data structures that are not
part of the standard Delphi runtime library.
The
second part of the book talks about parallel programming. You'll learn
about the problems that only occur in multithreaded code and explore
various approaches to fixing them effectively. The concluding chapters
provide instructions on writing parallel code in different ways – by
using basic threading support or focusing on advanced concepts such as
tasks and parallel patterns.
By the
end of this book, you'll have learned to look at your programs from a
totally different perspective and will be equipped to effortlessly make
your code faster than it is now.
What you will learn
- Get to grips with algorithmic complexity and learn how to recognize it
- Use tools to determine program runtime behavior
- Speed up programs by doing less instead of more
- Discover the internal workings of Delphi data structures
- Gain an understanding of Delphi's memory manager
- Find out how to write low-level parallel programs with TThread
- Use parallel patterns from the PPL and OTL libraries to write fast code
- Include external code, written in C or C++, in Delphi programs
Who this book is for
This
book is for all Delphi programmers. Whether you're a beginner or an
accomplished programmer, you will find something interesting. Even
though the focus is on the latest Delphi release, the code uses only
standard Delphi syntax without syntactic additions from the latest
releases, and most of it should compile and run in any Delphi from XE7
onward. If you're using an older version of Delphi, don't despair! Most
of the concepts in this book do not depend on a specific Delphi
version and will be useful for everyone.
