vpiotr

// findAllByAaa - find set of matching rows, empty set acceptable
Iterator found = Map.findAllByName("Jeffrey");

// find - get row selected by parameters, return null if not found
Employee employee = employees.find("Jeffrey");

// check - get row selected by parameters, throw exception if not found
Employee employee = employees.check("Jeffrey");

// get - this pattern in this context I would avoid since it can be understood as something between find & check
