box::register_S3_method
makes an S3 method for a given generic and
class known inside a module.
Arguments
- name
the name of the generic as a character string.
- class
the class name.
- method
the method to register (optional).
Details
If method
is missing, it defaults to a function named
name.class
in the calling module. If no such function exists, an error
is raised.
Methods for generics defined in the same module do not need to be registered
explicitly, and indeed should not be registered. However, if the user
wants to add a method for a known generic (defined outside the module, e.g.
print
), then this needs to be made known explicitly.
See the vignette at vignette('box', 'box')
for more information about
defining S3 methods inside modules.
Note
Do not call registerS3method
inside a
module, only use box::register_S3_method
. This is important for the
module’s own book-keeping.
