methods (version 3.3)

RMethodUtils: Method Utilities

Description

Utility functions to support the definition and use of formal methods. Most of these functions will not normally be called directly by the user.

Usage

getGeneric(f, mustFind=FALSE, where, package)
getGroup(fdef, recursive, where)
getGroupMembers(group, recursive = FALSE, character = TRUE)
getMethodsMetaData(f, where)
assignMethodsMetaData (f, value, fdef, where)
makeGeneric(f, fdef, fdefault =, group=list(), valueClass=character(),
            package =, signature = NULL, genericFunction = NULL,
            simpleInheritanceOnly = NULL)
makeStandardGeneric(f, fdef)
generic.skeleton(name, fdef, fdefault)
defaultDumpName(generic, signature)
doPrimitiveMethod(name, def, call= sys.call(sys.parent()),
                  ev = sys.frame(sys.parent(2)))
conformMethod(signature, mnames, fnames, f= , fdef, method)
matchSignature(signature, fun, where)
findUnique(what, message, where)
MethodAddCoerce(method, argName, thisClass, methodClass)
cacheMetaData(where, attach = TRUE, searchWhere = as.environment(where),
              doCheck = TRUE)
cacheGenericsMetaData(f, fdef, attach = TRUE, where, package, methods)
setPrimitiveMethods(f, fdef, code, generic, mlist)
missingArg(symbol, envir = parent.frame(), eval)
sigToEnv(signature, generic)
rematchDefinition(definition, generic, mnames, fnames, signature)
unRematchDefinition(definition)
asMethodDefinition(def, signature, sealed = FALSE, fdef)
addNextMethod(method, f, mlist, optional, envir)
insertClassMethods(methods, Class, value, fieldNames, returnAll)
balanceMethodsList(mlist, args, check = TRUE) # <- deprecated since R 3.2.0
