val get_this_type : InferIR.ProcAttributes.t ‑> InferIR.Typ.t option

Get the this type of a procedure

val get_type_name : InferIR.Typ.t ‑> string

val method_is_initializer : InferIR.Tenv.t ‑> InferIR.ProcAttributes.t ‑> bool

Check if the method is one of the known initializer methods.

val is_getter : InferIR.Typ.Procname.Java.t ‑> bool

Is this a getter proc name?

val is_subtype : InferIR.Tenv.t ‑> InferIR.Typ.Name.t ‑> InferIR.Typ.Name.t ‑> bool

Is the type a transitive subtype of the typename?

val is_subtype_of_str : InferIR.Tenv.t ‑> InferIR.Typ.Name.t ‑> string ‑> bool

Resolve typ_str in tenv, then check typ <: typ_str

val supertype_exists : InferIR.Tenv.t ‑> (InferIR.Typ.Name.t ‑> InferIR.Typ.Struct.t ‑> bool) ‑> InferIR.Typ.Name.t ‑> bool

Holds iff the predicate holds on a supertype of the named type, including the type itself

val supertype_find_map_opt : InferIR.Tenv.t ‑> (InferIR.Typ.Name.t ‑> 'a option) ‑> InferIR.Typ.Name.t ‑> 'a option

Return the first non-None result found when applying the given function to supertypes of the named type, including the type itself

val java_get_const_type_name : InferIR.Const.t ‑> string

Get the name of the type of a constant

val java_get_vararg_values : InferIR.Procdesc.Node.t ‑> InferIR.Pvar.t ‑> Idenv.t ‑> InferIR.Exp.t list

Get the values of a vararg parameter given the pvar used to assign the elements.

val proc_calls : (InferIR.Typ.Procname.t ‑> InferIR.ProcAttributes.t option) ‑> InferIR.Procdesc.t ‑> (InferIR.Typ.Procname.t ‑> InferIR.ProcAttributes.t ‑> bool) ‑> (InferIR.Typ.Procname.t * InferIR.ProcAttributes.t) list

Return the callees that satisfy filter.

val override_find : ?⁠check_current_type:bool ‑> (InferIR.Typ.Procname.t ‑> bool) ‑> InferIR.Tenv.t ‑> InferIR.Typ.Procname.t ‑> InferIR.Typ.Procname.t option

Return a method which overrides procname and satisfies f (including procname itself when check_current_type is true, which it is by default).

val override_exists : ?⁠check_current_type:bool ‑> (InferIR.Typ.Procname.t ‑> bool) ‑> InferIR.Tenv.t ‑> InferIR.Typ.Procname.t ‑> bool

Return true if applying the given predicate to an override of procname (including procname itself when check_current_type is true, which it is by default) returns true.

val override_iter : (InferIR.Typ.Procname.t ‑> unit) ‑> InferIR.Tenv.t ‑> InferIR.Typ.Procname.t ‑> unit

Apply the given predicate to procname and each override of procname. For the moment, this only works for Java

is_runtime_exception tenv class_name checks if classname is of type java.lang.RuntimeException

val check_class_attributes : (InferIR.Annot.Item.t ‑> bool) ‑> InferIR.Tenv.t ‑> InferIR.Typ.Procname.t ‑> bool

tests whether any class attributes (e.g.,

val check_current_class_attributes : (InferIR.Annot.Item.t ‑> bool) ‑> InferIR.Tenv.t ‑> InferIR.Typ.Procname.t ‑> bool
