All Implemented Interfaces:

public class CopiedFromAspectPatch
extends AbstractPatch

Patch to break the link between working copies and copies.

Formerly, when a document was copied, it was given a cm:source property on the cm:copiedfrom aspect - a d:noderef property. During checkout, the working copy was given the cm:workingcopy aspect and the cm:copiedfrom aspect was assumed to be present. However, the ordinality of the cm:copiedfrom's cm:source property didn't match up with the checkin-checkout 1:1 relationship.

This patch works in two parts:

cm:copiedfrom

• cm:source is transformed into a peer association, cm:original
• The aspect is removed where the source no longer exists

cm:workingcopy

• cm:source is transformed into a peer association, cm:workingcopylink
• The original is given aspect cm:checkedout
• The copy keeps cm:workingcopy

Since:

4.0

Method Detail

setPatchDAO

public void setPatchDAO(PatchDAO patchDAO)

Parameters:

patchDAO - additional queries

setNodeDAO

public void setNodeDAO(NodeDAO nodeDAO)

Parameters:

nodeDAO - provides query support

setDictionaryService

public void setDictionaryService(org.alfresco.service.cmr.dictionary.DictionaryService dictionaryService)

Parameters:

dictionaryService - type and aspect resolution

setBehaviourFilter

public void setBehaviourFilter(BehaviourFilter behaviourFilter)

Parameters:

behaviourFilter - used to switch off cm:auditable behaviour

setRuleService

public void setRuleService(RuleService ruleService)

Parameters:

ruleService - used to disable rules

setBatchThreads

public void setBatchThreads(int batchThreads)

Parameters:

batchThreads - the number of threads that will write child association changes

setBatchSize

public void setBatchSize(int batchSize)

Parameters:

batchSize - the number of child associations that will be modified per transaction

setBatchMaxQueryRange

public void setBatchMaxQueryRange(int batchMaxQueryRange)

Parameters:

batchMaxQueryRange - the largest ID range that the work provider can query for. Lower this if the DB resultset retrieval causes memory issues prior to the query limit being applied.

checkProperties

protected void checkProperties()

Description copied from class: AbstractPatch

Check that the schema version properties have been set appropriately. Derived classes can override this method to perform their own validation provided that this method is called by the derived class.

Overrides:

checkProperties in class AbstractPatch

applyInternal

protected java.lang.String applyInternal()
                                  throws java.lang.Exception

Description copied from class: AbstractPatch

This method does the work. All transactions and thread-safety will be taken care of by this class. Any exception will result in the transaction being rolled back. Integrity checks are downgraded for the duration of the transaction.

Specified by:

applyInternal in class AbstractPatch

Returns:

Returns the report (only success messages).

Throws:

java.lang.Exception - anything can be thrown. This must be used for all failures.
