Interface Executor

public interface Executor

This interface must be implemented by all executors to be used by workflow engines. Executors implements this interface must also have public default constructor so that the ExecutionManager will be able to create instances of an executor.

Field Summary

static java.lang.String	RCS_ID
static boolean	RCS_ID_RECORDED

Method Summary

ActivityResult

execute(WorkflowContext ctx, WorkItemProcessActivity activity, ActivityResult event, java.lang.String runMode) This procedure is called when a workflow engine decides to execute a function per activity definition.

Field Detail

RCS_ID

public static final java.lang.String RCS_ID

RCS_ID_RECORDED

public static final boolean RCS_ID_RECORDED

Method Detail

execute

public ActivityResult execute(WorkflowContext ctx,
                              WorkItemProcessActivity activity,
                              ActivityResult event,
                              java.lang.String runMode)
                       throws ExecutionException

This procedure is called when a workflow engine decides to execute a function per activity definition.

Parameters:

ctx - : {$link WorkflowContext} within which the routine engine is running

activity - :{$link WorkItemProcessActivity} to be executed

event - : {$link ActivityResult} result to cause this activity to be executed, usually an upstream instance result.

runMode - : String indicates that if this is a cancel call or not (possible values are Function.RUN_MODE, Function.CANCEL_MODE etc. Function)

Returns:

activityResult : {$link ActivityResult} either returned by an activity function, or created by the executor to indicate the execution status.

Throws:

ExecutionException - when fails to perform the execution for the given activity. This exception will result in the process jumping into an error process mode.
