Field Summary

static int	CORRECT Defines that the operation is correct
static int	INCORRECT Defines that the operation is incorrect
static int	INCORRECT_MISSING Defines that this object is associated to the failure "missing-suboperations", what means that all performed operations are correct, but there are missing some suboperations to complete the actual operation
static int	UNKNOWN Defines an unknown correctness
