Module dev_node_process.erl ¶

A device that implements the singleton pattern for processes specific to an individual node.

Description¶

This device uses the local-name@1.0 device to register processes with names locally, persistenting them across reboots.

Definitions of singleton processes are expected to be found with their names in the node_processes section of the node message.

augment_definition/2*	Augment the given process definition with the node's address.
generate_test_opts/0*	Helper function to generate a test environment and its options.
generate_test_opts/1*
info/1	Register a default handler for the device.
lookup/4*	Lookup a process by name.
lookup_execute_test/0*	Test that a process can be spawned, executed upon, and its result retrieved.
lookup_no_spawn_test/0*
lookup_spawn_test/0*
spawn_register/2*	Spawn a new process according to the process definition found in the node message, and register it with the given name.
