## Defunct Functions in the Methods Package

### 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)

### 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`seemsS4Object` was similar to `isS4` and superseded by the introduction of the S4 bit in R 2.4.0.
