Class InsertEmptyBranch

java.lang.Object

de.aristaflow.adept2.core.changeoperations.InsertEmptyBranch

public class InsertEmptyBranch
extends java.lang.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.

Method Detail

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 on

split - the splitting node

join - 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 on

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 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 on

split - the splitting node

join - 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 on

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 it is possible
