Excerpt of article text...
In the first two parts of this series, I explained about data structures and we looked at a few examples. Today we'll continue that discussion and we'll also look at data abstraction, or hiding your data structure. I'll explain why that's important in a bit.
More Basic Structures
You might have thought we'd have exhausted all the basic data structures, but there are a few more we haven't covered. Some of these get rather advanced, so I'm not planning on comprehensive coverage, but I thought I'd at least go over them briefly so that you know what they are and if you're interested I'm sure you can find more information about them.
MemoryBlocks
A MemoryBlock is a strange sort of data structure support by REALbasic. In a way, it's not much of a structure at all -- it's just raw memory set aside for whatever you'd like to do with it. As such, it's very powerful and fast -- there isn't the overhead associated with datatypes and variables and other stuff -- but it's also more complicated.
