A Task Type defines a routine to process a Task.
For a Task defined as...
{ "type": "ls1.echo", "output":"Hello World!"} }
... the "ls1.echo" corresponds to a Task Type that is pre-defined by LavishScript. The Task Type is responsible for interpreting the rest of the Task, which in this case indicates that it should output "Hello World!".
Creating a Task Type
Task Types can be defined by LavishScript:Scripts.
- Here we provide a template you can follow! Also found at gist.github.com
objectdef mytasks_Controller { variable taskmanager TaskManager=${LMAC.NewTaskManager["mytaskstest"]} method Initialize() { This:AddTaskType["{\"name\":\"my first task type\",\"object\":\"MyTasks\",\"method\":\"Task_Template\"}"] } method Shutdown() { LMAC.TaskManager["mytaskstest"]:Destroy } method AddTaskType(string jsonData) { variable int64 id id:Set[${LMAC.NewTaskType["${jsonData.Escape}"].ID}] if ${id} { echo "LMAC: Task Type ${id} added: ${LMAC.TaskType[${id}].Name.Escape}" } } method Task_Template() { switch ${Context.TaskState} { case Start echo ${Context(type)} ${Context.Timestamp} ${Context.ElapsedMS} ${Context.Task} ${Context.TaskState} instant=${Context.Task.IsInstant} ${Context.Task.Args} break case Continue ; echo ${Context(type)} ${Context.Timestamp} ${Context.ElapsedMS} ${Context.Task} ${Context.TaskState} instant=${Context.Task.IsInstant} ${Context.Task.Args} break case Stop echo ${Context(type)} ${Context.Timestamp} ${Context.ElapsedMS} ${Context.Task} ${Context.TaskState} instant=${Context.Task.IsInstant} ${Context.Task.Args} break } } ; begin a test! method Start() { TaskManager:BeginTask["{\"type\":\"my first task type\",\"duration\":1.0,\"my setting\":\"my setting value\"}"] } } variable(global) mytasks_Controller MyTasks function main() { MyTasks:Start while 1 { waitframe } } atom atexit() { }
This example can be saved as, for example, mytasks.iss.
- Output
Running the script will produce approximately this output (your timestamps and IDs will likely differ from this example):
LMAC: Task Type 161 added: my first task type taskpulseargs 271000984 0 164 Start instant=FALSE {"duration":1.000000,"my setting":"my setting value","type":"my first task type"} taskpulseargs 271001984 1000 164 Stop instant=FALSE {"duration":1.000000,"my setting":"my setting value","type":"my first task type"}
