Description

The Delphi VCL is lacking a good container for large numbers of key/value pairs. This submission contains a suitable container with a lookup mechanism based on a generic hash table implementation. The latter can be used to store any kind of object that implements a specific interface (IHashable) to provide a key in string form. The key/value store container shows how to create a suitable wrapper class to store non-object data into such a hash table. The container can also store its content to a stream or file and reload it from such a source. The data format used can be modified by supplying a custom streamer to the container.
