hasFullSupport
A boolean indicating whether all known function name inferences are supported.
bitFlags
An integer that stores a serialization of the support
object. Useful when
storing a function name (or lack thereof) for later comparisons along with
details on whether the function name was inferable at all.
isSubsetOf(otherFlags): boolean
Helper method for comparing bitFlags
. Returns true
if it is a subset of
otherFlags
.
isSupersetOf(otherFlags: number): boolean
Helper method for comparing bitFlags
. Returns true
if it is a superset of
otherFlags
.
