rpc

COMPAS runs in many different environments, but some environments limit the availablity of libraries, for example, when running COMPAS from an IronPython environment like Rhino/Grasshopper, plenty of the CPython libraries such as numpy, scipy, etc are not usable.

To workaround this limitation, COMPAS provides two mechanisms to access the CPython environment seemlessly from any other Python environment. One of them is called XFunc (compas.utilities.XFunc) and it works very effectively to make single, but expensive calls that execute long-running bits of code. The other one is called RPC, which stands for Remote Procedure Call` and it allows to create a transparent proxy/connection between our environment and the one where all the fast libraries and dependencies of COMPAS are installed. It also allows to re-use the same process for many small calls, making it much more effective for the cases in which the required functionality is not easily isolated in one long-running function.

Proxy

In order to use the RPC communication package, we create an instance of the Proxy class to one specific package that we want to have access to. After the proxy is created, it behaves as a regular Python on which the functions of the proxied package are available as if they were directly present in our environment.

Proxy

Create a proxy object as intermediary between client code and remote functionality.
