LSP in OO programming?

Question

Am I right in thinking the full name of the LSP is the Liskoff Substitution Principle? I'm having trouble finding an [online] source to cite for any information on this... it seems to be a cornerstone of OOP, and yet I'm having trouble finding definitions.

Answer 1

Yes, you are right. It's spelled Liskov which is probably why you can't find a citation. Here's the link. One of the better resources regarding this is Robert C. Martin's Agile Software Development Principles Patterns and practices book.

Answer 2

You got the name right.
