REstate
REstate is a portable state-flow system. It allows you to define a set of possible states that a program can exist in and what input will cause the transition between any two states. When it transitions into a given state, you can define an action that will execute arbitrary code. This can be used to build complex, but deterministic and predefined systems, such as workflow systems or distributed systems.
A Schematic
may be defined on one server or workstation, but then used on others. REstateMachine
s can call arbitrary code through the connector system, provided the connector exists on the system where it is running.
var schematic = REstateHost.Agent
.CreateSchematic<string, string>("LoggerMachine")
.WithState("Created", state => state
.AsInitialState())
.WithState("Ready", state => state
.WithTransitionFrom("Created", "log")
.WithReentrance("log")
.WithAction("log info", onEntry => onEntry
.DescribedAs("Logs the payload as a message.")
.WithSetting(
key: "messageFormat",
value: "{schematicName}({machineId}) entered {state} on {input}. Message: {payload}")))
.Build();
The same schematic in YML (YamlDotNet):
SchematicName: LoggerMachine
InitialState: Created
States:
- Value: Created
Transitions:
- Input: log
ResultantState: Ready
- Value: Ready
Transitions:
- Input: log
ResultantState: Ready
Action:
ConnectorKey:
Identifier: log info
Configuration:
messageFormat: '{schematicName}({machineId}) entered {state} on {input}. Message: {payload}'
Description: Logs the payload as a message.
As well as JSON or any other format really.
