ComplexityChecker (Constructor)

ComplexityChecker(source, filename, tree, select, ignore, args)

Constructor

source (list of str): source code to be checked
filename (str): name of the source file
tree (ast.Module): AST tree of the source code
select (list of str): list of selected codes
ignore (list of str): list of codes to be ignored
args (dict): dictionary of arguments for the miscellaneous checks

ComplexityChecker.__checkLineComplexity

__checkLineComplexity()

Private method to check the complexity of a single line of code and the median line complexity of the source code.

Complexity is defined as the number of AST nodes produced by a line of code.

ComplexityChecker.__checkMcCabeComplexity

__checkMcCabeComplexity()

Private method to check the McCabe code complexity.
