  - booleanExpressionComplexity
```
public static int booleanExpressionComplexity(net.sourceforge.pmd.lang.ast.Node expr)
```
    Evaluates the number of paths through a boolean expression. This is the total number of && and || operators appearing in the expression. This is used in the calculation of cyclomatic and n-path complexity.
    
    Parameters:
    
    expr - Expression to analyse
    
    Returns:
    
    The number of paths through the expression
