Class "allIndex", index class representing a subscript for all elements of a vector or an array dimension

Description

When used as a subscript for a vector object x, this is equivalent to seq(length(x)). When used as a subscript for the i-th dimension of an array object x, this is equivalent to seq(dim(x)[i]).

Objects from the Class

Objects can be created by calls of the form new("allIndex"). Objects from this class can not be modified and they are all equivalent.

Slots

.Data:

Object of class "logical", this is always equal to TRUE.

Extends

Class "logical", directly. Class "vectorIndex", directly.

Methods

Signature components for the methods are:

x+scalar:

Add scalar to x. Result is x.

scalar+x:

Add scalar to x. Result is x.

x*scalar:

Multiply x by scalar. Result is x.

scalar*x:

Multiply x by scalar. Result is x.

dim(x) <- value

Set a dimension on x. If value is of length 2, this may create a "matrixIndex".

x[i]:

Subset x. Result is i.

x[]:

Subset x with the subscript missing. Result is x.

x[i] <- value:

Subassign x. Results in an error (as objects from class "allIndex" are not mutable.

x[[i]] <- value:

Subassign x. Results in an error (as objects from class "allIndex" are not mutable.

allNA(x):

Are all elements of x NA? Result is always FALSE.

anyNA(x):

Is any element of x NA? Result is always FALSE.

initialize(.Object):

Initialize an object from class "allIndex".

length(x):

Return the length of x which is always Inf.

length(x) <- value:

Modify the length of x. Always results in an error.
