Detailed Description
template<class E, class T>
class GrAL::grid_function_hash_base< E, T >
Implements a grid_function on hash-basis.This can be used if arrays are not possible, or for partial grid functions.
Access operations have slightly different semantics for total and partial grid-functions, so corresponding derivations grid_function_hash and partial_grid_function_hash are provided.
The main difference between a partial grid function and a hashed total grid function is the handling of read access to undefined item: in the total version this is an error (program termination in debug mode!), whereas for the partial version a default value (which can be manipulated seperately) is returned.
- Todo:
- Optimization: Could use
hash_table<element_handle,T>instead ofhash_table<Element,T>. However, in some cases it is not possible to implement equality testing of the underlying elements without referring to the grid.
