Class dbObjectId — dbObjectId-class • RPostgreSQL

A helper (mixin) class to provide external references in an R/S-Plus portable way.

Objects from the Class

A virtual Class: No objects may be created from it.

Slots

Id:: Object of class "integer" this is an integer vector holding an opaque reference into a C struct (may or may not be a C pointer, may or may not have length one).

Methods

coerce: signature(from = "dbObjectId", to = "integer"): ...
coerce: signature(from = "dbObjectId", to = "numeric"): ...
coerce: signature(from = "dbObjectId", to = "character"): ...
format: signature(x = "dbObjectId"): ...
print: signature(x = "dbObjectId"): ...

A cleaner mechanism would use external references, but historically this class has existed mainly for R/S-Plus portability.
