copy of the current counter.

toString

public java.lang.String toString()

Overrides:

toString in class Index

currentElement

public int currentElement()

Description copied from class: Index

Get the current element's index into the 1D backing array.

Overrides:

currentElement in class Index

Returns:

the current element's index into the 1D backing array.

incr

public int incr()

Description copied from class: Index

Increment the current element by 1. Used by IndexIterator. General rank, with subclass specialization.

Overrides:

incr in class Index

Returns:

currentElement()

setDim

public void setDim(int dim,
          int value)

Description copied from class: Index

set current element at dimension dim to v

Overrides:

setDim in class Index

Parameters:

dim - set this dimension

value - to this value

set

public Index set(int[] index)

Description copied from class: Index

Set the current element's index. General-rank case.

public Index set0(int v)

Description copied from class: Index

set current element at dimension 0 to v

Overrides:

set0 in class Index

Parameters:

v - set 0th dimension index to this value

set1

public Index set1(int v)

Description copied from class: Index

set current element at dimension 1 to v

Overrides:

set1 in class Index

Parameters:

v - set dimension 1 index to this value

Returns:

this, so you can use A.get(i.set(i))

set

public Index set(int v0,
        int v1)

Description copied from class: Index

set current element at dimension 0,1 to v0,v1

Overrides:

set in class Index

Parameters:
