_get_binding_time()

def CellMLToNektar.pycml.mathml_and._get_binding_time (   self )

private

Return the binding time of the enclosing <apply> element.

Short-circuit if a static False operand occurs before any dynamic
operands, returning static.  Otherwise return the least upper bound
of operand binding times, as usual.

evaluate()

def CellMLToNektar.pycml.mathml_and.evaluate

(

self

)

Return the logical conjunction of the operands.

Evaluates operands in the order given in the file, and will
short-circuit at the first which evaluates to False.
