java.lang.Object

de.aristaflow.adept2.core.changeoperations.DeleteBorderNodes

public class DeleteBorderNodes
extends Object

Use this change operation to delete the split/start loop and join/end loop nodes. The mentioned nodes can only be deleted, if there is only one branch between them. 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 possible (concerning structural correctness) to delete start and end nodes of the current block in the given template.

Parameters:

template - the template where the block nodes should be deleted

split - the beginning of the split

join - the end of it

Returns:

True, if deletion is possible

isPossible

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

Checks if it is possible (concerning structural correctness) to delete start and end nodes of the current block in the given template. If it is not possible the reasons are stored in the checkReport.

Parameters:

template - the template where the block nodes should be deleted

split - the beginning of the split

join - the end of it

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 possible (concerning structural and state-based correctness) to delete start and end nodes of the current block in the given instance.

Parameters:

instance - the changeable instance where the block nodes should be deleted

split - the beginning of the split

join - the end of it

Returns:

True, if deletion 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 delete start and end nodes of the current block in the given instance. If it is not possible the reasons are stored in the checkReport.

Parameters:

instance - the changeable instance where the block nodes should be deleted

split - the beginning of the split

join - the end of it

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
