Method Summary

protected OperationReport	batchDeleteNodes(List<Long> ids) Will delete the nodes identified by the ids parameter.
OperationReport	deleteNodes(List<Long> targetIds) NodeDeletionHandler.deleteNodes(List)
protected List<Long>	detectLockedNodes(List<Long> nodeIds) Given a list of node ids, returns a sublist corresponding to the ids of the nodes which cannot be deleted according to the specs.
protected List<SuppressionPreviewReport>	diagnoseSuppression(List<Long> nodeIds) Given their ids, that method should check the nodes and actually report the informations as specified in NodeDeletionHandler.simulateDeletion(List).
protected FolderDao<org.squashtest.tm.domain.requirement.RequirementFolder,org.squashtest.tm.domain.requirement.RequirementLibraryNode>	getFolderDao() The implemention should return which FolderDao to use depending on the end domain object.

Method Detail

getFolderDao

protected FolderDao<org.squashtest.tm.domain.requirement.RequirementFolder,org.squashtest.tm.domain.requirement.RequirementLibraryNode> getFolderDao()

Description copied from class: AbstractNodeDeletionHandler

The implemention should return which FolderDao to use depending on the end domain object.

Specified by:

getFolderDao in class AbstractNodeDeletionHandler<org.squashtest.tm.domain.requirement.RequirementLibraryNode,org.squashtest.tm.domain.requirement.RequirementFolder>

Returns:

an appropriate FolderDao.

diagnoseSuppression

protected List<SuppressionPreviewReport> diagnoseSuppression(List<Long> nodeIds)

Description copied from class: AbstractNodeDeletionHandler

Given their ids, that method should check the nodes and actually report the informations as specified in NodeDeletionHandler.simulateDeletion(List). See AbstractNodeDeletionHandler.detectLockedNodes(List) for details regarding the input list.

Specified by:

diagnoseSuppression in class AbstractNodeDeletionHandler<org.squashtest.tm.domain.requirement.RequirementLibraryNode,org.squashtest.tm.domain.requirement.RequirementFolder>

Parameters:

nodeIds - the complete list of the nodes involved in that report.

Returns:

a list of reports summarizing in human readable format what will happen.

detectLockedNodes

protected List<Long> detectLockedNodes(List<Long> nodeIds)

Description copied from class: AbstractNodeDeletionHandler

Given a list of node ids, returns a sublist corresponding to the ids of the nodes which cannot be deleted according to the specs. The input list includes all the nodes and their children in the directory structure. The implementation is responsible to fetch any other dependencies needed for the completion of its task. The implementation is not required to resolve which folders are locked : this abstract class will handle that on the basis of the returned value.

Specified by:

detectLockedNodes in class AbstractNodeDeletionHandler<org.squashtest.tm.domain.requirement.RequirementLibraryNode,org.squashtest.tm.domain.requirement.RequirementFolder>

Parameters:

nodeIds - all the node ids.

Returns:

the sublist of node ids that should NOT be deleted.

deleteNodes

public OperationReport deleteNodes(List<Long> targetIds)

Description copied from class: AbstractNodeDeletionHandler

NodeDeletionHandler.deleteNodes(List)

Specified by:

deleteNodes in interface NodeDeletionHandler<org.squashtest.tm.domain.requirement.RequirementLibraryNode,org.squashtest.tm.domain.requirement.RequirementFolder>

Overrides:

deleteNodes in class AbstractNodeDeletionHandler<org.squashtest.tm.domain.requirement.RequirementLibraryNode,org.squashtest.tm.domain.requirement.RequirementFolder>

Parameters:

targetIds - the list of node ids selected by the user.

Returns:

an OperationReport saying what happened.

batchDeleteNodes

protected OperationReport batchDeleteNodes(List<Long> ids)

Description copied from class: AbstractNodeDeletionHandler

Will delete the nodes identified by the ids parameter. Those nodes have been identified as legal for deletion and the implementation should only care of deleting them and unbinding them from the rest of the domain.

Specified by:

batchDeleteNodes in class AbstractNodeDeletionHandler<org.squashtest.tm.domain.requirement.RequirementLibraryNode,org.squashtest.tm.domain.requirement.RequirementFolder>

Parameters:

ids - the doomed node ids.

Returns:
