Detailed Description

Fortran Array Boxes (generally called FABs) are objects constructed to interface with arrays in Fortran. Useful operations can be performed upon FABs in C++, and they provide a convenient interface to Fortran when it is necessary to retreat into that language for doing arithmetic operations when performance matters.

FArrayBox is derived from BaseFab<Real>. FArrayBox adds additional useful capabilities which make sense for Real types, such as I/O and L**p norms.

The C pre-processor macro `CH_SPACEDIM' must be defined to use this class. The internal precision of FArrayBox objects is set by defining either `CH_USE_FLOAT' or `CH_USE_DOUBLE'

This class does NOT provide a copy constructor or assignment operator.

Member Function Documentation

virtual void FArrayBox::define ( const Box &  a_box,
int  a_ncomp,
Real *  a_alias = NULL 
) [inline, virtual]

Defines FArrayBox with the data space allocated but not inititialized. a_ncomp is the number of components (variables) at each data point in the Box.

virtual void FArrayBox::define ( const Interval &  a_comps,
FArrayBox &  a_original 
) [inline, virtual]

Constructs an 'aliased' BaseFab of the requested interval of the argument BaseFab. This BaseFab does not allocate any memory, but sets its data pointer into the memory pointed to by the argument BaseFab. It is the users responsiblity to ensure this aliased BaseFab is not used after the original BaseFab has deleted its data ptr (resize, define(..) called, or destruction, etc.).

This aliased BaseFab will also generate side effects (modifying the values of data in one will modify the other's data).

This aliased BaseFab will have a_comps.size() components, starting at zero.

Modifies this FArrayBox by dividing all values by the scalar Real a_r.

FArrayBox& FArrayBox::divide ( Real  a_r  ) 

Modifies this FArrayBox by dividing all values by the scalar Real a_r.

Referenced by NodeFArrayBox::divide().

FArrayBox& FArrayBox::divide ( Real  a_r,
int  a_comp,
int  a_numcomp = 1 
)

Modifies this FArrayBox by dividing all values by the scalar Real a_r. For given range of components.

FArrayBox& FArrayBox::divide ( Real  a_r,
const Box &  a_subbox,
int  a_comp = 0,
int  a_numcomp = 1 
)

Modifies this FArrayBox by dividing all values by the scalar Real a_r. For given range of components and within given a_subbox.

FArrayBox& FArrayBox::operator/= ( const FArrayBox &  a_x  ) 

Modifies this FArrayBox by pointwise division of the values by the argument FArrayBox. You might come to grief if the domains of the FArrayBoxes don't match.

FArrayBox& FArrayBox::divide ( const FArrayBox &  a_x  ) 

Modifies this FArrayBox by pointwise division by the values in the argument FArrayBox. You might come to grief if the domains of the FArrayBoxes don't match. The same as the /= operator.

FArrayBox& FArrayBox::divide ( const FArrayBox &  a_src,
int  a_srccomp,
int  a_destcomp,
int  a_numcomp = 1 
)

Modifies this FArrayBox by pointwise division by values in the argument FArrayBox. Divides this FArrayBox's components (a_destcomp : a_destcomp+a_numcomp-1) by a_src's components (a_srccomp : a_srccomp+a_numcomp-1) where the domains of the two FArrayBoxes intersect.

FArrayBox& FArrayBox::divide ( const FArrayBox &  a_src,
const Box &  a_subbox,
int  a_srccomp,
int  a_destcomp,
int  a_numcomp = 1 
)

Modifies this FArrayBox by pointwise division by values in the argument FArrayBox. Divides this FArrayBox's components (a_destcomp : a_destcomp+a_numcomp-1) by a_src's components (a_srccomp : a_srccomp+a_numcomp-1) where the domain of this FArrayBox intersects the a_subbox. NOTE: a_subbox must be contained in this FAB.

FArrayBox& FArrayBox::divide ( const FArrayBox &  a_src,
const Box &  a_srcbox,
const Box &  a_destbox,
int  a_srccomp,
int  a_destcomp,
int  a_numcomp = 1 
)

Modifies this FArrayBox by pointwise division by values in the argument FArrayBox. Divides this FArrayBox's components (a_destcomp : a_destcomp+a_numcomp-1) in the Box a_destbox by a_src's components (a_srccomp : a_srccomp+a_numcomp-1) in the Box a_srcbox. Corresponding locations within the two FArrayBoxes are indexed relative to a_srcbox and a_destbox, and will in general not be the same. The a_srcbox and a_destbox must be same size. The results are UNDEFINED if the a_src and dest FArrayBoxes are the same and the a_srcbox and a_destbox overlap.
