labscript_utils.ls_zprocess.ProcessTree

class labscript_utils.ls_zprocess.ProcessTree(shared_secret=None, allow_insecure=False, zlock_host=None, zlock_port=7339, zlog_host=None, zlog_port=7340)

Bases: ProcessTree

A singleton zprocess.ProcessTree configured with settings from labconfig for security, zlock and zlog. Being a singleton is not enforced - the class can still be instantiated as normal - but calling the .instance() classmethod will give the singleton.
