methods-defunct {methods}
Description
Defunct functions in package methods.
Usage
getAccess(ClassDef) getClassName(ClassDef) getClassPackage(ClassDef) getExtends(ClassDef) getProperties(ClassDef) getPrototype(ClassDef) getSubclasses(ClassDef) getVirtual(ClassDef) getAllMethods(f, fdef, where) mlistMetaName (name, package) removeMethodsObject(f, where) seemsS4Object(object) allGenerics() trySilent(expr) traceOn(what, tracer=browseAll, exit=NULL) traceOff(what)
Details
The first block of functions should be replaced by direct access to the slots, or by use of higher-level alternatives.
The functions and corresponding slots are:
getAccess |
"access" |
getClassName |
"className" |
getClassPackage |
"package" |
getExtends |
"contains" |
getProperties |
"slots" |
getPrototype |
"prototype" |
getSubclasses |
"subclasses" |
getVirtual |
"virtual" |
getAllMethods replicated the behavior of getMethods, which should be called instead to obtain approximately the old behavior of getAllMethods. However, a better substitution is to use findMethods, which returns a simpler structure.
mlistMetaName was a utility to return the mangled name for the object that stored the MethodsList representation of the methods for a particular generic function, typically in the environment of a package. These objects are no longer used.
removeMethodsObject removed the metadata object containing methods for f.
seemsS4Object was similar to isS4 and superseded by the introduction of the S4 bit in R 2.4.0.
allGenerics is superseded by getGenerics.
trySilent(ex) was a deprecated equivalent of try(e, silent=TRUE); in R programming it is typically more efficient and flexible to work with something like tryCatch(ex, error = function(e) e) instead.
The functions traceOn and traceOff have been replaced by extended versions of the functions trace and untrace.
