Store and get data in pad objects

Description

Get and store information in a pad. pad can be used on the lefthand side of an assignment to store information in an object and as normal function call to retrieve previously stored information.

Usage

pad(x, item)
pad(x, item, ...) <- value

Arguments

x	the object where the information is stored.
item	the item to be stored or extracted.
value	the value to be stored
...	additional arguments (??? are these really possible? !!!)

Details

This is a generic function. There are methods for x of class objectPad. The generic works with the slot pad of x. Currently there is no check if there is one.

To remove an item use pad(x,item) <- NULL. So, by definition, items may not have the value NULL.

padcheck checks if item has a value and if so returns TRUE. Otherwise it returns FALSE.

Value

The requested item.

If item is missing a named list containing all stored items.

Methods

x = "objectPad", item = "missing"

get all items stored in the pad x, as a named list.

x = "objectPad", item = "ANY"

get the requested item from the pad x.

x = "ANY", item = "missing"

get all items stored in the pad of x as a named list.

x = "ANY", item = "ANY"
