documentation get class definition description get the definition of a class usage getclass class force false where getclassdef class where package inherits true arguments class the character string name of the class often with a package attribute as noted below under package force if true return null if the class is undefined otherwise an undefined class results in an error where environment from which to begin the search for the definition by default start at the top level global environment and proceed through the search list package the name or environment of the package asserted to hold the definition if it is a non empty string it is used instead of where as the first place to look for the class note that the package must be loaded but need not be attached by default the package attribute of the class argument is used if any there will usually be a package attribute if class comes from class x for some object inherits logical should the class definition be retrieved from any enclosing environment and also from the cache if false only a definition in the environment where will be returned details class definitions are stored in metadata objects in a package namespace or other environment where they are defined when packages are loaded the class definitions in the package are cached in an internal table therefore most calls to getclassdef will find the class in the cache or fail to find it at all unless inherits is false in which case only the environment s defined by package or where are searched the class cache allows for multiple definitions of the same class name in separate environments with of course the limitation that the package attribute or package name must be provided in the call to value the object defining the class if the class definition is not found getclassdef returns null while getclass which calls getclassdef either generates an error or if force is true returns a simple definition for the class the latter case is used internally but is not typically sensible in user code the non null returned value is an object of class classrepresentation use functions such as setclass and setclassunion to create class definitions
