type lock_effect =
| Lock of Absint.HilExp.t list

simultaneously acquire a list of locks

| Unlock of Absint.HilExp.t list

simultaneously release a list of locks

| LockedIfTrue of Absint.HilExp.t list

simultaneously attempt to acquire a list of locks

| GuardConstruct of {
guard : Absint.HilExp.t;
lock : Absint.HilExp.t;
acquire_now : bool;
}

mutex guard construction - clang only

| GuardLock of Absint.HilExp.t

lock underlying mutex via guard - clang only

| GuardLockedIfTrue of Absint.HilExp.t

lock underlying mutex if true via guard - clang only

| GuardUnlock of Absint.HilExp.t

unlock underlying mutex via guard - clang only

| GuardDestroy of Absint.HilExp.t

destroy guard and unlock underlying mutex - clang only

| NoEffect

function call has no lock-relevant effect

effect of call plus Hil expressions being un/locked, if known

type thread =
| BackgroundThread
| MainThread
| MainThreadIfTrue
| UnknownThread
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 -> Absint.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_android_lifecycle_method : IR.Tenv.t -> IR.Procname.t -> bool

is method a known Android UI thread callback (eg Activity.onCreate)
