Detailed Description

Warning

This is an advanced API!
only for advanced programmers, You might be lost if you are a beginner.

Event Direct Message

• Node 1

  std.node.emit(node_2, 'say', 'hello!')

Event Bus Registering

Parents

• Root

  std.node.spawn(node_1)
  std.node.spawn(node_3)

• Node 1

Function Documentation

emit()

local function emit	(	application	,
		key	,
