NoEffect
function call has no lock-relevant effect
effect of call plus Hil expressions being un/locked, if known
val is_thread_utils_method : string -> IR.Procname.t -> bool
return true if the given method name is a utility class for checking what thread we're on TODO: clean this up so it takes only a procname
val get_lock_effect : IR.Procname.t -> IR.HilExp.t list -> lock_effect
describe how this procedure behaves with respect to locking
val get_thread_assert_effect : IR.Procname.t -> thread
In Java, certain methods can be used to assert execution on a specific kind of thread, or return a boolean equivalent to such a fact.
val get_current_class_and_annotated_superclasses : (IR.Annot.Item.t -> bool) -> IR.Tenv.t -> IR.Procname.t -> (IR.Typ.name * IR.Typ.name list) option
val is_recursive_lock_type : IR.Typ.name -> bool
type annotation_trail
=
|
DirectlyAnnotated
the method is directly annotated as such
|
Override of IR.Procname.t
it overrides a method annotated in a super class
|
SuperClass of IR.Typ.name
the method's class or a super class of that is annotated as such
Type documenting why a method is considered as annotated with a certain annotation
val compare_annotation_trail : annotation_trail -> annotation_trail -> int
val find_override_or_superclass_annotated : (IR.Annot.Item.t -> bool) -> IR.Tenv.t -> IR.Procname.t -> annotation_trail option
check if a method's transitive annotations satisfy the given predicate
val annotated_as_worker_thread : IR.Tenv.t -> IR.Procname.t -> bool
val runs_on_ui_thread : IR.Tenv.t -> IR.Procname.t -> bool
is method not transitively annotated
@WorkerThread
and is modeled or annotated@UIThread
or equivalent?
val is_modeled_ui_method : IR.Tenv.t -> IR.Procname.t -> bool
is method a known Android UI thread callback (eg
Activity.onCreate
)
