FileChannel.MapMode is a typesafe enumeration used for defining file-mapping modes.
It provides three modes: PRIVATE (copy-on-write), READ_ONLY, and READ_WRITE for controlling access to mapped file regions.
These modes are used when mapping a file region into memory using FileChannel.map().
Each mode has a specific behavior regarding data modification and synchronization with the underlying file.
The toString() method provides a descriptive string representation of the mapping mode.
A typesafe enumeration for file-mapping modes.
