SimpleList-class: SimpleList objects

Description

The (non-virtual) SimpleList class extends the List virtual class.

Details

The SimpleList class is the simplest, most generic concrete implementation of the List abstraction. It provides an implementation that subclasses can easily extend.

In a SimpleList object the list elements are stored internally in an ordinary list.

Constructor

See the List man page for a quick overview of how to construct List objects in general.

The following constructor is provided for SimpleList objects:

SimpleList(...): Takes possibly named objects as elements for the new SimpleList object.

Accessors

Same as for List objects. See the List man page for more information.

Coercion

All the coercions documented in the List man page apply to SimpleList objects.

Subsetting

Same as for List objects. See the List man page for more information.

Looping and functional programming

Same as for List objects. See ?`List-utils` for more information.

Displaying

When a SimpleList object is displayed, the "Simple" prefix is removed from the real class name of the object. See classNameForDisplay for more information about this.

## Displaying a SimpleList object:
x1 <- SimpleList(a=letters, i=Rle(22:20, 4:2))
class(x1)

## The "Simple" prefix is removed from the real class name of the
## object:
x1

library(IRanges)
x2 <- IntegerList(11:12, integer(0), 3:-2, compress=FALSE)
class(x2)

## The "Simple" prefix is removed from the real class name of the
## object:
x2

## This is controlled by internal helper classNameForDisplay():
classNameForDisplay(x2)
