Class WorkflowLinker

java.lang.Object

com.axelor.workflow.compiler.WorkflowLinker

public final class WorkflowLinker
extends Object

The cross-workflow checks: every <call> ref resolves, and no chain of calls returns to where it started, resolved through a WorkflowCatalog.

Method Summary

Modifier and Type	Method	Description
static WorkflowCatalog.WorkflowRef	firstUnresolved(List<WorkflowCatalog.WorkflowRef> refs, WorkflowCatalog catalog)	The first of refs the catalog cannot resolve, or null if all resolve.
static boolean	hasCycle(WorkflowCatalog.WorkflowRef self, List<WorkflowCatalog.WorkflowRef> rootRefs, WorkflowCatalog catalog)	Whether following rootRefs returns to self; the visited set bounds the walk even over an existing cycle.
static List<Violation>	link(WorkflowPlan plan, WorkflowCatalog catalog, WorkflowCatalog.WorkflowRef self)	Check a compiled plan's refs and cycles against catalog; self is the workflow being linked, which may not be in the catalog yet.
static List<WorkflowCatalog.WorkflowRef>	subflowRefs(Workflow workflow, WorkflowCatalog catalog)	The refs of a workflow not yet compiled: compile it, or none when it does not compile.
static List<WorkflowCatalog.WorkflowRef>	subflowRefs(WorkflowPlan plan)	The target name of each call, unresolved.
static List<WorkflowCatalog.WorkflowRef>	subflowRefs(WorkflowPlan plan, WorkflowCatalog catalog)	Each call's target identity, including calls written inside embedded bodies, since a body calling its way back to an ancestor is a real cycle.

Method Details

link

public static List<Violation> link(WorkflowPlan plan,
 WorkflowCatalog catalog,
 WorkflowCatalog.WorkflowRef self)

Check a compiled plan's refs and cycles against catalog; self is the workflow being linked, which may not be in the catalog yet.

subflowRefs

public static List<WorkflowCatalog.WorkflowRef> subflowRefs(WorkflowPlan plan)

The target name of each call, unresolved.

subflowRefs

public static List<WorkflowCatalog.WorkflowRef> subflowRefs(Workflow workflow,
 WorkflowCatalog catalog)

The refs of a workflow not yet compiled: compile it, or none when it does not compile. A null catalog leaves them unresolved.

subflowRefs

public static List<WorkflowCatalog.WorkflowRef> subflowRefs(WorkflowPlan plan,
 WorkflowCatalog catalog)

Each call's target identity, including calls written inside embedded bodies, since a body calling its way back to an ancestor is a real cycle.

firstUnresolved

public static WorkflowCatalog.WorkflowRef firstUnresolved(List<WorkflowCatalog.WorkflowRef> refs,
 WorkflowCatalog catalog)

The first of refs the catalog cannot resolve, or null if all resolve.

hasCycle

public static boolean hasCycle(WorkflowCatalog.WorkflowRef self,
 List<WorkflowCatalog.WorkflowRef> rootRefs,
 WorkflowCatalog catalog)

Whether following rootRefs returns to self; the visited set bounds the walk even over an existing cycle.
