Lazy Data Streams
Lazy Data Streams is a mix between an iterator and a collection. It can be expanded by lazy calculation of an extra member.
History
Lazy Data Streams are used in different functional languages e.g.
The advantage of a lazy data stream is
- That you can use functional techniques on possible infinite streams of data
- You still have access to previous elements in a calculation by an iterator
- You only calculate the necessary elements
Example of Lazy Data Streams
- Lazy Data Streams to calculate all Fibonacci number.
- All even Fibonacci number.
- All even Fibonacci number who's sum is less than 100.
