Class LCOM96b

LCOM96b (Lack of Cohesion of Methods, Handerson et al., 1996)

Formula: LCOM96b = (1/a) * Σ((1/m) * (m - μ(A))) for all attributes A

Where:

• m is the number of methods in the class
• a is the number of attributes (fields) in the class
• μ(A) is the number of methods that access an attribute (field) A
• The formula measures how methods are connected through attributes

Returns a value between 0 and 1:

• 0: perfect cohesion (all methods access all attributes)
• 1: complete lack of cohesion (each method accesses its own attribute)
