Modules

During the last years, LEDA's main include directory has grown to more than 400 include files. As a result, the include directory was simply too complex so that new features were hard to identify. We therefore introduced modules to better organize LEDA's include structure. Starting from version 5.0 LEDA consists of the several modules:

• core (LEDA/incl/core/)
  Module core stores all basic data types (array, list, set, partition, etc.), all dictionary types (dictionary, d_array, h_array sortseq, etc.), all priority queues, and basic algorithms like sorting.

• numbers (LEDA/incl/numbers/)
  Module numbers stores all LEDA number types (integer, real, rational, bigfloat, polynomial, etc.) as well as data types related to linear algebra (vector, matrix, etc.) and all additional data types and functions related to numerical computation (fpu, numerical analysis, etc.)

• graph (LEDA/incl/graph/)
  Module graph stores all graph data types, all types related to graphs and all graph algorithms.

• geo (LEDA/incl/geo/)
  Module geo stores all geometric data types and all geometric algorithms.

• graphics (LEDA/incl/graphics/)
  Module graphics stores all include files and data types related to our graphical user interfaces, i.e. window, graphwin and geowin.

• coding (LEDA/incl/coding/)
  Module codings contains all data types and algorithms relating to compression and cryptography.

• system (LEDA/incl/system/)
  Module system contains all data types that offer system-related functionality like date, time, stream, error handling and memory management.

• internal (LEDA/incl/internal/)
  Module internal contains include files that are needed for LEDA's maintenance or for people who want to implement extension packages.

• beta (LEDA/incl/beta/)
  Module beta contains data types that are not fully tested.

• exp (LEDA/incl/exp/)
  Module exp contains data types that are experimental. Most of these data types can be used as implementation parameters for the data types dictionary, priority queues, d_array, and sortseq. Starting with LEDA version 6.5, experimental data types are no longer available in pre-compiled object code packages.
