Vectors Library v.050702

By Alexey Chernobaev.

Freeware + source 05 Sep 2006


Vectors is a class library for Object Pascal (Delphi, Free Pascal v.0.99.15 and higher) which implements vectors (dynamically sized arrays) based on different Object Pascal's simple types including all integer and real types, booleans, pointers and strings. These vectors resemble TList class type from Delphi VCL but in addition to the common operations like insert and delete they offer a wide range of operations depending on the type of the vector elements -sorting, searching, arithmetic vector operations for number-type vectors, logical operations for boolean vectors and so on. The library also implements a range of derivative and additional classes - sparse vectors, matrixes, queues, stacks, dictionaries, streams. Vectors library goes in the source form and can be freely used for any purpose.
