Detailed Description

Allows to setup and store user-specified log records of algorithmic information.

The class LogRecord allows to setup and store user-specified log records of algorithmic information consisting of numerical values during runtime.

A log record comprises arbitrarily many LogRecordItems stored in a simple singly-linked list. Within these items, the actual numerical values of the algorithmic to be logged as well as settings defining their output format is stored. Several commonly-used output formats are pre-defined within so-called PrintSchemes.

Additionally, a log record stores two important settings: (i) the LogFrequency defining whether the information is stored at each iteration or only at the start or end, respectively; (ii) the file, e.g. a file or the screen, to which the whole log record including all its items can be printed.

Finally, it is interesting to know that LogRecords can be setup by the user and flushed to UserInterface classes. Internally, LogRecords are stored as basic singly-linked within a LogCollection.
