Algorithm (const Kernel &, Ex &) | |
Initialise the algorithm with a reference to the expression tree, but do not yet do anything with this tree. More... | |
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. More... | |
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'). More... | |
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. More... | |
bool | check_consistency (iterator) const |
Given an expression top node, check index consistency. More... | |
bool | check_index_consistency (iterator) const |
bool | check_degree_consistency (iterator) const |
Given an expression top node, check differential form degree consistency. More... | |

bool | is_termlike (iterator) |
Determine structure (version-2) More... | |
bool | is_factorlike (iterator) |
bool | is_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. More... | |

bool | prod_wrap_single_term (iterator &) |
bool | prod_unwrap_single_term (iterator &) |
void | force_prod_wrap (iterator &) |
Wrap a term in a product, irrespective of its parent (it usually makes more sense to call the safer prod_wrap_single_term above). More... | |
bool | separated_by_derivative (iterator, iterator, iterator check_dependence) const |
Figure out whether two objects (commonly indices) are separated by a derivative operator, as in
\[ \partial_{a}{A_{b}} C^{b} \] . More... | |
