Class DeleteEmptyBranch

java.lang.Object

de.aristaflow.adept2.core.changeoperations.DeleteEmptyBranch

public class DeleteEmptyBranch
extends java.lang.Object

Deletes an empty branch between a split and its corresponding join node. Call isPossible first to check if the deletion is valid, than call perform operation to execute the change. TODO Refactor; use a common interface for change operations.

Method Detail

isPossible

public static boolean isPossible(Template template,
                                 Node split,
                                 Node join)

Checks if it is valid (concerning structural correctness) to delete the given branch from the template.

Parameters:

template - the template where the branch should be deleted

split - the splitting node

join - the joining node

Returns:

True, if deletion is possible

isPossible

public static boolean isPossible(Template template,
                                 Node split,
                                 Node join,
                                 CheckReport checkReport)

Checks if it is valid (concerning structural correctness) to delete the given branch from the template. If it is not possible the reasons are stored in the checkReport.

Parameters:

template - the template where the branch should be deleted

split - the splitting node

join - the joining node

checkReport - 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 deletion is possible

isPossible

public static boolean isPossible(ChangeableInstance instance,
                                 Node split,
                                 Node join)

Checks if it is valid (concerning structural and state-based correctness) to delete the given branch from the given instance.

Parameters:

instance - the changeable instance where the branch should be deleted

split - the splitting node

join - the joining node

Returns:

True, if deletion is possible

isPossible

public static boolean isPossible(ChangeableInstance instance,
                                 Node split,
                                 Node join,
                                 CheckReport checkReport)

Checks if it is valid (concerning structural and state-based correctness) to delete the given branch from the instance. If it is not possible the reasons are stored in the checkReport.

Parameters:

instance - the changeable instance where the branch should be deleted

split - the splitting node

join - the joining node

checkReport - 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 deletion is possible

performOperation

public static void performOperation(ChangeableTemplate template,
                                    Node split,
                                    Node join)

Deletes an empty branch between split and join in the given template.

Parameters:

template - the template where the branch is to be deleted

split - the splitting node

join - the joining node

performOperation

public static void performOperation(ChangeableTemplate template,
                                    Node split,
