Class LCOM4

LCOM4 (Hitz & Montazeri, 1995)

Formula: LCOM4 = number of connected components in the method-field graph

Where:

• A connected component is a maximal set of methods connected through shared fields
• Methods are connected if they access the same field or are transitively connected

Returns a value >= 1:

• 1: perfect cohesion (all methods are connected)
• Higher values: increasing lack of cohesion
