## A Lockable List Structure with Constraints on Content

### Description

Container class that specializes the list construct of R to provide content and access control

### Creating Objects

`new('container', x = [list], content = [character], locked = [logical])`

### Slots

x
  list of entities that are guaranteed to share a certain property
content
  tag describing container contents
locked
  boolean indicator of locked status. Value of TRUE implies assignments into the container are not permitted

### Methods

Class-specific methods:

`content(container)`
  returns `content` slot of argument
`locked(container)`
  returns `locked` slot of argument

Standard methods defined for 'container':

`show(container)`
  prints container
`length(container)`
  returns number of elements in the container
`[[(index)` and `[[(index, value)`
  access and replace elements in the container
`[(index)`
  make a subset of a container (which will itself be a container)

### Examples

      x1 <- new("container", x=vector("list", length=3), content="lm")
      lm1 <- lm(rnorm(10)~runif(10))
      x1[[1]] <- lm1
