Detailed Description

Compression oracle based on absolute difference.

Constructor & Destructor Documentation

◆ AbsDiff() [1/2]

AbsDiff ( float tolerance = -1.0f)

Note
The default value of -1 means it's un-initialized!

◆ AbsDiff() [2/2]

AbsDiff ( const AbsDiff & )
default

◆ ~AbsDiff()

~AbsDiff ( )
default
