Public Member Functions

 rename_dummies (const Kernel &, Ex &, std::string, std::string)
 
virtual bool can_apply (iterator)
 
virtual result_t apply (iterator &)
 
- Public Member Functions inherited from cadabra::Algorithm
 Algorithm (const Kernel &, Ex &)
 Initialise the algorithm with a reference to the expression tree, but do not yet do anything with this tree.
 
virtual ~Algorithm ()
 
void set_progress_monitor (ProgressMonitor *)
 Provide the algorithm with a ProgressMonitor object on which to register (nested) progress information, to be reported out-of-band to a client.
 
result_t apply_generic (bool deep=true, bool repeat=false, unsigned int depth=0)
 The main entry points for running algorithms, which traverse the tree post-order ('child before parent').
 
result_t apply_generic (iterator &, bool deep, bool repeat, unsigned int depth)
 
result_t apply_pre_order (bool repeat=false)
 Apply algorithm with alternative traversal: starting from the top node, traverse the tree pre-order ('parent before child') and once the algorithm acts at a given node, do not traverse the subtree below anymore.
 
bool check_consistency (iterator) const
 Given an expression top node, check index consistency.
 
bool check_index_consistency (iterator) const
 
bool check_degree_consistency (iterator) const
 Given an expression top node, check differential form degree consistency.
 
void report_progress (const std::string &, int todo, int done, int count=2)
 
index_iterator begin_index (iterator it) const
 
index_iterator end_index (iterator it) const
 
unsigned int number_of_indices (iterator it)
 
std::string get_index_set_name (iterator it) const
 
bool rename_replacement_dummies (iterator, bool still_inside_algo=false)
 Rename the dummies in the sub-tree starting with head at the given iterator.
 
Ex_set_t dependencies (iterator it) const
 Determine all the Coordinate dependencies of the object at 'it'.
 
- Public Member Functions inherited from cadabra::ExManip
 ExManip (const Kernel &, Ex &)
 
bool prod_wrap_single_term (iterator &)
 Take a single non-product node in a sum and wrap it in a product node, so it can be handled on the same footing as a proper product.
 
bool prod_unwrap_single_term (iterator &)
 
bool sum_wrap_single_term (iterator &)
 
bool sum_unwrap_single_term (iterator &)
 
bool is_single_term (iterator)
 Is the indicated node a single term in an expression?
 
bool is_nonprod_factor_in_prod (iterator)
 
void force_node_wrap (iterator &, std::string)
 Wrap a term in a product or sum in a node with indicated name, irrespective of its parent (it usually makes more sense to call the safer prod_wrap_single_term or sum_wrap_single_term above).
