Class LCOMStar

LCOM* (Fernandez & Pena, 2006) - also known as LCOM-star

Formula: LCOM* = (number of method pairs without shared attributes) / (total method pairs)

Where:

• Method pairs are counted once (not twice)
• Shared attributes means both methods access at least one common field

Returns a value between 0 and 1:

• 0: perfect cohesion (all method pairs share attributes)
• 1: no cohesion (no method pairs share attributes)
