ensureClassRegistration: Ensure Class Registration

In rappster/classr: Class instances for rapid prototyping

Description

Ensures that classes are registrated in a sense that they are recognized by isClass.

Usage

ensureClassRegistration(cl, strict = FALSE, ...)

Arguments

cl	Signature argument. Object containing class information. This usually corresponds to the name of a class.
strict	logical. TRUE: error if cl is already a class (checked by isClass); FALSE: if class already exists it is not reset.
...	Further arguments passed to subsequent functions/methods. In particular: setOldClass

Details

Esentially, this functions simply calls setOldClass in order to register the classes. A call to this method might make sense inside .onLoad and .onAttach of your packages.

Examples

## Not run: 

## NOTE //
## Keeping the default for 'where'  that is used by 'setOldClass',
## i.e. simply *not* providing a value in the call to 'ensureClassRegistration',
## only works as long as your package has not been fully loaded yet
ensureClassRegistration(cl = "TestClass")
isClass("TestClass")
ensureClassRegistration(cl = "TestClass")
try(ensureClassRegistration(cl = "TestClass", strict = TRUE))
ensureClassRegistration(cl = c("TestClass1", "TestClass2"))
isClass("TestClass1")
isClass("TestClass2")


## End(Not run)
