Collections v.1.1.1

Components > Tools > Base classes

By DeHL Team.

Freeware + source 10 Feb 2011


Collections is a package consisting of basic and advanced generic collections for Delphi. This package uses the standard Generics.Defaults and Generics.Collections units to access the comparer and equality comparer functionality. The collection classes do not inherit the base ones in Generics.Collections.

Collections package is fully documented as XMLDoc in the source code. You can use Help Insight to view function, type and class descriptions directly from the IDE. The library is fully tested using DUnit test cases.

Components > Tools > Base classes

By DeHL Team.

Freeware + source 04 Oct 2010


A generic code library for Delphi.

The most important features of DeHL for now are:

  • A set of generic collections classes (List, Dictionary, HashSet, etc).
  • Linq-like extensions (called Enex) for collections which allow writing queries on collection classes.
  • Date/Time functionality all combined in a few structures (somehow equivalent to .NET's DateTime structure)
  • Type Support concept that defines a set of default "support classes" for each built-in Delphi types (used as defaults in collections). Custom "type support" classes can be registered for your custom data types.
  • BigCardinal and BigInteger data types.
  • Smart pointers in Delphi.

Components > Date and Time > Other

By DeHL Team.

Freeware + source 25 Apr 2014


All the time zone information used by the project is provided by tz database project. This database is used in quite a few systems out there including BSDs, GNU LibC, Java, Oracle, MacOS, Linux and etc.

TZDB is made of three modules:

  • TZUpdate, a small command line utility that takes as input the path to the tz rule files and generates a pascal source file filled with pre-packed constants.
  • TZDB, a package that contain only one unit: TimeZones. This unit implements a new class, TBundledTimeZone, derived from TTimeZone. This package is basically all you need.
  • TZVisualizer, a small VCL project that extracts time zone information from a given time zone. It writes all time intervals in a given year, their offset and etc.
