Description Methods Author(s) See Also Examples
A class to record version number information. This class is used to
report versions; to add version information to your own class, use
Versioned-class
.
The following are defined; package developers may write additional methods.
new("Versions", ...)
Create a new Versions-class
instance,
perhaps with named version elements (the contents of
...
) added. Named elements of versions
are
character strings that can be coerced using
package_version
, or package_version
instances, Versions-class
objects.
object["id"]
Obtain version information "id"
from object
.
object["id"] <- value
Create or update version information "id"
on instance object
.
object[["id"]]
Obtain version information "id"
from object
. The result is a list of integers, corresponding to entries in the version string.
object[["id"]] <- value
Create or update version information "id"
on instance object
.
object$id
Obtain version information "id"
from object
.The result is a list of integers, corresponding to entries in the version string.
object$id <- value
Create or update version
information "id"
on instance object
.
show(object)
Display version information.
updateObject(object)
Update object
to the
current Versions-class
representation. Note that this does not
update another class that uses Versions-class
to track the
class version.
as(object, "character")
Convert object
to character representation, e.g., 1.0.0
object1 < object2
Compare object1
and object2
using version class information. Symbols in addition to <
are admissible; see ?Ops
