Buffer
Basic Buffer usage and the meanings of capacity, position, and limit.
This is a historical learning note and may contain outdated or incomplete understanding.
Basic Usage
Write data into the Buffer.
Call flip().
Read data from the Buffer.
Call clear() or compact().
Principle
There are three properties:
- capacity
- position
- limit
The meanings of position and limit depend on whether the Buffer is in read mode or write mode. The meaning of capacity is always the same regardless of the Buffer’s mode.
