{\bf data modification functions}

template<class T>
BaseFab< T > & BaseFab< T >::shift (  int    idir,
int    n_cell

Modifies the domain of this BaseFab by shifting it n_cells indexing positions in coordinate direction idir. Directions are zero-based. It is an error if not 0 <= idir < SpaceDim.There is no effect upon the array memory.

template<class T>
BaseFab< T > & BaseFab< T >::shift (  const IntVect &    v )  [inline]
 

{\bf domain modification functions}

Modifies the domain of this BaseFab by shifting. Equivalent to fab.shift(0,iv[0]).shift(1,iv[1]) .... There is no effect upon the array memory.

template<class T>
BaseFab< T > & BaseFab< T >::shiftHalf (  const IntVect &    num_halfs )  [inline]
 

Modifies the domain of this BaseFab by shifting by half indices. Equivalent to fab.shiftHalf(0,iv[0]).shiftHalf(1,iv[1]) ... There is no effect upon the array memory.

template<class T>
BaseFab< T > & BaseFab< T >::shiftHalf (  int    dir,
int    num_halfs
)  [inline]
 

Modifies the domain of this BaseFab by shifting by "half" indices, thereby converting the Box from type CELL to NODE or vice-versa. fab.shiftHalf(0,1) shifts the domain to the right by 1/2 cells. fab.shiftHalf(1,-3) shifts the domain in the -j direction by 3/2 cells. NOTE: If num\_halfs is EVEN the shift is num\_halfs/2 full zones and hence will not change the type. This is: fab.shifthalf(4) == fab.shift(2). Directions are zero-based. It is an error if not 0 <= dir < SpaceDim. There is no effect upon the array memory.

template<class T>
int BaseFab< T >::size (  const Box &    b,
const Interval &    comps

{\bf linearization functions}

Returns the size, in number of bytes, of a flat linear representation of the data in this object in the area defined by the input Box R and the component Interval comps. The size does not include the size of R and comps.
