Detailed Description

Complex Fortran Array Boxes (generally called CFArrayBoxs) 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.

CFArrayBox is derived from BaseFab<Complex>. CFArrayBox adds additional useful capabilities which make sense for Complex 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 CFArrayBox 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 CFArrayBox::define ( const Box a_box,
int  a_comps,
Complex *  a_alias = NULL 
) [inline, virtual]

Make BaseFab with desired domain and number of components. Existing data is lost. Data is in uninialized state.

Reimplemented from BaseFab< Complex >.

References BaseFab< T >::define().

CFArrayBox& CFArrayBox::operator= ( CFArrayBox &&  a_in  ) 

virtual void CFArrayBox::define ( const Interval a_comps,
CFArrayBox 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.
