MODULE NOTES:
|
|
|
|
A. There are two philosophies to building string classes:
|
|
1. Hide the underlying buffer & offer API's allow indirect iteration
|
|
2. Reveal underlying buffer, risk corruption, but gain performance
|
|
|
|
We chose the second option for performance reasons.
|
|
|
|
B Our internal buffer always holds capacity+1 bytes.
