Specified by:

visit in interface TreeVisitor<MigratingProcessElementInstanceTopDownWalker.MigrationContext>

Parameters:

obj - a reference to the node

canMigrate

protected abstract boolean canMigrate(MigratingProcessElementInstance instance)

instantiateScopes

protected abstract void instantiateScopes(MigratingScopeInstance ancestorScopeInstance,
                                          MigratingScopeInstanceBranch executionBranch,
                                          List<ScopeImpl> scopesToInstantiate)

migrateProcessElementInstance

protected void migrateProcessElementInstance(MigratingProcessElementInstance migratingInstance,
                                             MigratingScopeInstanceBranch migratingInstanceBranch)

collectNonExistingFlowScopes

protected List<ScopeImpl> collectNonExistingFlowScopes(ScopeImpl scope,
                                                       MigratingScopeInstanceBranch migratingExecutionBranch)

Returns a list of flow scopes from the given scope until a scope is reached that is already present in the given MigratingScopeInstanceBranch (exclusive). The order of the returned list is top-down, i.e. the highest scope is the first element of the list.
