clang::tidy::bugprone::filter::relatedness_heuristic Namespace Reference

This namespace contains the implementations for the suppression of diagnostics from similarly-used ("related") parameters. More...

Classes
class	AccessedSameMemberOf
	Implements the heuristic that marks two parameters related if the same member is accessed (referred to) inside the current function's body. More...
class	AppearsInSameExpr
	Implements the heuristic that marks two parameters related if there is a usage for both in the same strict expression subtree. More...
class	PassedToSameFunction
	Implements the heuristic that marks two parameters related if there are two separate calls to the same function (overload) and the parameters are passed to the same index in both calls, i.e f(a, b) and f(a, c) passes b and c to the same index (2) of f(), marking them related. More...
class	Returned
	Implements the heuristic that marks two parameters related if different ReturnStmts return them from the function. More...
