def CellMLToNektar.pycml.mathml_piecewise._get_binding_time (   self)
private 
Return the binding time of this expression.

The binding time will be computed recursively and cached.
It will also be made available as an attribute in the XML.

It is computed by taking the least upper bound of the binding
times of (some of) the conditions and cases.

Condition & case binding times are computed in the order given
in the file.  If a condition is static with value False, its
associated case is not considered.  If a condition is static
with value True, subsequent conditions & cases and the
otherwise (if present) will not be considered.

Classify variables in this expression according to how they are used.

In the process, compute and return a set of variables on which
this expression depends.

If dependencies_only then the variable classification will not be
done, only dependencies will be analysed.  This is useful for doing
a 'light' re-analysis if the dependency set has been reduced; if the
set has increased then the topological sort of equations may need to
be redone.

The function needs_special_treatment may be supplied to override the
default recursion into sub-trees.  It takes a single sub-tree as
argument, and should either return the dependency set for that
sub-tree, or None to use the default recursion.  This is used when
re-analysing dependencies after applying lookup tables, since table
lookups only depend on the keying variable.

def CellMLToNektar.pycml.mathml_piecewise.tree_complexity (   self,

) 
Calculate a rough estimate of the computation time for
evaluating this <piecewise> element.

The real evaluation time will generally depend on run time
data, which makes things tricky.  Here we estimate by taking
the sum of the complexities of the conditions and the maximum
of the complexity of the cases, in order to obtain an upper
bound.

If lookup_tables is True, then assume we're using lookup tables
where possible.
If algebraic is True, the complexity is calculated as a dictionary,
mapping node types to the number of occurences of that type.

If self.rootNode.num_lookup_tables exists, this method will
update the count of lookup tables based on this expression,
unless the argument 'count_tables' is False or algebraic is True.
