compares name checks for both internal and regular
generics. is_s3_method()
builds names of all possible generics for that
function and then checks if any of them actually is a generic.
is_s3_generic(fname, env = parent.frame())
is_s3_method(fname, env = parent.frame())
fname |
Name of function as a string. Need name of function because it's impossible to determine whether or not a function is a S3 method based only on its contents. |
env |
Environment to search in. |
