engforge.properties.cached_system_property

class cached_system_property(fget=None, fset=None, fdel=None, doc=None, desc=None, label=None, stochastic=False)

Bases: system_property

A system property that caches the result when nothing changes. Use for expensive functions since the checking adds some overhead

You can initalize just the functions, or precreate the object but with meta @system_property def function(…): < this uses __init__ to assign function

@system_property(desc=’really nice’,label=’funky function’) def function(…): < this uses __call__ to assign function

Methods

get_func_return	ensures that the function has a return annotation, and that return annotation is in valid sort types

__call__(fget=None, fset=None, fdel=None, doc=None)

get_func_return(func)

ensures that the function has a return annotation, and that return annotation is in valid sort types
