Class ActivityAwareScopeExecutionCollector

java.lang.Object
  org.camunda.bpm.engine.impl.tree.ActivityAwareScopeExecutionCollector

All Implemented Interfaces:

TreeVisitor<PvmExecutionImpl>

public class ActivityAwareScopeExecutionCollector
extends Object
implements TreeVisitor<PvmExecutionImpl>

Only collects scope executions that execute ancestor scopes of the given commonChildScope.

In regular process execution, collects all scope executions. Yet in cases where the execution tree is not aligned to the activity tree (such as with compensation throwing executions), executions are skipped if they execute an activity that is not a parent/ancestor of the given commonChildScope.
