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' must be defined to use this class. The internal precision of FArrayBox objects is set by defining either `CH' or `CH'

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

Constructs an invalid FArrayBox with no memory.

FArrayBox::FArrayBox const Box a_box,
int  a_ncomp,
Real a_alias = NULL

FArrayBox::FArrayBox const Interval a_comps,
FArrayBox a_original
[inline]
 

Construct an aliaed FArrayBox. See BaseFab class for details.

Member Function Documentation

void FArrayBox::abs const Box a_subbox,
int  a_comp = 0,
int  a_numcomp = 1
 

Modifies this FArrayBox by replacing eahc value with its absolute value, for components (a_comp : a_comp+a_numcomp-1) and within the a_subbox.

void FArrayBox::abs int  a_comp,
int  a_numcomp = 1
 

Modifies this FArrayBox by replacing each value with its absolute value, for components (a_comp : a_comp+a_numcomp-1).

void FArrayBox::abs  ) 
 

Modifies this FArrayBox by replacing each value with its absolute value.

virtual void FArrayBox::define const Interval a_comps,
BaseFab< Real > &  a_original
[inline, virtual]
 

This is here only to make the Intel compiler stop warning about partial override.

Reimplemented from BaseFab< Real >.

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.

int  a_ncomp,

[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.
