IntegerFunction3D

class cherab.lhd.emc3.cython.IntegerFunction3D

Bases: object

Cython optimised class for representing an arbitrary 3D function returning a integer.

Using __call__() in cython is slow. This class provides an overloadable cython cdef evaluate() method which has much less overhead than a python function call.

For use in cython code only, this class cannot be extended via python.

To create a new function object, inherit this class and implement the evaluate() method. The new function object can then be used with any code that accepts a function object.

Methods

__call__

Evaluate the function f(x, y, z)
