      • setReadThrough

        public void setReadThrough​(boolean isReadThrough)
        Description copied from interface: Indexer
        Activates 'read through' behaviour for this indexer. Rather than accessing the database through the current (potentially old) transaction, it will use a discrete read only transaction for each node it indexes. This avoids 'stale' nodes building up in the caches during long reindex runs.
        Specified by:
        setReadThrough in interface Indexer
        Parameters:
        isReadThrough - boolean

      • createNode

        public void createNode​(org.alfresco.service.cmr.repository.ChildAssociationRef relationshipRef)
        Description copied from interface: Indexer
        Create an index entry when a new node is created. A node is always created with a name in a given parent and so a relationship ref is required.
        Specified by:
        createNode in interface Indexer
        Parameters:
        relationshipRef - ChildAssociationRef

      • updateNode

        public void updateNode​(org.alfresco.service.cmr.repository.NodeRef nodeRef)
        Description copied from interface: Indexer
        Update an index entry due to property changes on a node. There are no strucural impications from such a change.
        Specified by:
        updateNode in interface Indexer
        Parameters:
        nodeRef - NodeRef

      • deleteNode

        public void deleteNode​(org.alfresco.service.cmr.repository.ChildAssociationRef relationshipRef)
        Description copied from interface: Indexer
        Delete a node entry from an index. This implies structural change. The node will be deleted from the index. This will also remove any remaining refernces to the node from the index. The index has no idea of the primary link.
        Specified by:
        deleteNode in interface Indexer
        Parameters:
        relationshipRef - ChildAssociationRef

      • createChildRelationship

        public void createChildRelationship​(org.alfresco.service.cmr.repository.ChildAssociationRef relationshipRef)
        Description copied from interface: Indexer
        Create a refernce link between a parent and child. Implies only (potential) structural changes
        Specified by:
        createChildRelationship in interface Indexer
        Parameters:
        relationshipRef - ChildAssociationRef

      • updateChildRelationship

        public void updateChildRelationship​(org.alfresco.service.cmr.repository.ChildAssociationRef relationshipBeforeRef,
                                    org.alfresco.service.cmr.repository.ChildAssociationRef relationshipAfterRef)
        Description copied from interface: Indexer
        Alter the relationship between parent and child nodes in the index. This can be used for:
        1. rename,
        2. move,
        3. move and rename,
        4. replace
        This could be implemented as a delete and add but some implementations may be able to optimise this operation.
        Specified by:
        updateChildRelationship in interface Indexer
        Parameters:
        relationshipBeforeRef - ChildAssociationRef
        relationshipAfterRef - ChildAssociationRef

      • deleteChildRelationship

        public void deleteChildRelationship​(org.alfresco.service.cmr.repository.ChildAssociationRef relationshipRef)
        Description copied from interface: Indexer
        Delete a relationship between a parent and child. This will remove a structural route through the index. The index has no idea of reference and primary relationships and will happily remove the primary relationship before refernces which could remain. Use delete to ensure all strctural references are removed or call this sure you are doing an unlink (remove a hard link in the unix file system world).
        Specified by:
        deleteChildRelationship in interface Indexer
        Parameters:
        relationshipRef - ChildAssociationRef

      • detectNodeChanges

        public void detectNodeChanges​(org.alfresco.service.cmr.repository.NodeRef nodeRef,
                              org.alfresco.service.cmr.search.SearchService searcher,
                              java.util.Collection<org.alfresco.service.cmr.repository.ChildAssociationRef> addedParents,

                              java.util.Collection<org.alfresco.service.cmr.repository.NodeRef> updatedNodes)
        Description copied from interface: Indexer
        Does a database vs index comparison for the given created/updated/renamed/referenced nodeRef in order to determine the set of indexing operations required
        Specified by:

        Parameters:
        nodeRef - the nodeRef to process
