Class InsertEmptyBranch
- java.lang.Object
-
- de.aristaflow.adept2.core.changeoperations.InsertEmptyBranch
-
public class InsertEmptyBranch extends Object
Insert a branch between a split and its corresponding join node. Call isPossible first to check if the insertion is valid, than call perform operation to execute the change. TODO Refactor; use a common interface for change operations.

isPossible
public static boolean isPossible(Template template, Node split, Node join)
Checks if it is possible (concerning structural correctness) to insert an empty branch between split and join in the template.- Parameters:
template
- the template the change is performed onsplit
- the splitting nodejoin
- the joining node- Returns:
- True, if it is possible
-
isPossible
public static boolean isPossible(Template template, Node split, Node join, CheckReport checkReport)
Checks if it is possible (concerning structural correctness) to insert an empty branch between split and join in the template. If it is not possible the reasons are stored in the checkReport.- Parameters:
template
- the template the change is performed onsplit
- the splitting nodejoin
- the joining nodecheckReport
- a checkReport object which can be filled with the reason why the isPossible failed (i.e. in the case the method returns false), may be null- Returns:
- True, if it is possible
-
isPossible
public static boolean isPossible(ChangeableInstance instance, Node split, Node join)
Checks if it is possible (concerning structural correctness) to insert an empty branch between split and join in the given instance.- Parameters:
instance
- the instance the change is performed onsplit
- the splitting nodejoin
- the joining node- Returns:
- True, if it is possible
-
isPossible
public static boolean isPossible(ChangeableInstance instance, Node split, Node join, CheckReport checkReport)
Checks if it is possible (concerning structural and state-based correctness) to insert an empty branch between split and join in the given instance. If it is not possible the reasons are stored in the checkReport.- Parameters:
instance
- the instance the change is performed onsplit
- the splitting nodejoin
- the joining nodecheckReport
- a checkReport object which can be filled with the reason why the isPossible failed (i.e. in the case the method returns false), may be null- Returns:
- True, if it is possible
-
performOperation
public static void performOperation(SessionToken session, ChangeableTemplate template, Node split, Node join)
Inserts an empty branch between split and join in the given template.- Parameters:
session
- The session which is used to check for access rights on this method.template
- the related templatesplit
- the splitting nodejoin

-
performOperation
public static void performOperation(SessionToken session, ChangeableTemplate template, Node split, Node join, UpdateManager updateManager)
Inserts an empty branch between split and join in the given template (with updateManager).- Parameters:
session
- The session which is used to check for access rights on this method.template
- the related templatesplit
- the splitting nodejoin
- the joining nodeupdateManager
- the manager who controls the update of the visual graph components.
-
performOperation
public static void performOperation(SessionToken session, ChangeableInstance instance, Node split, Node join)
