Interface NodeService

@org.alfresco.api.AlfrescoPublicApi
public interface NodeService
Interface for public and internal node and store operations.

Amongst other things, this service must enforce the unique name check as mandated by the duplicate entity in the model.

    <type name="cm:folder">
       ...
       <associations>
          <child-association name="cm:contains">
             ...
             <duplicate>false</duplicate>
          </child-association>
       </associations>
    </type>
 
When duplicates are not allowed, and the cm:name property of a node changes, then the DuplicateChildNodeNameException exception must be thrown. Client code can catch this exception and deal with it appropriately.

deleteNode
@Auditable(parameters="nodeRef")
void deleteNode(NodeRef nodeRef)
         throws InvalidNodeRefException
Deletes the given node.

All associations (both children and regular node associations) will be deleted, and where the given node is the primary parent, the children will also be cascade deleted.

Node stores may be mapped to an associated archive node store. For example, Alfresco ships with the mapping
workspace://SpacesStore .. maps to .. archive://SpacesStore.
When a node is deleted:

  • If there *is a mapping* from the node's current store to an archive store, the node is first copied to the archive store
  • If there *is no mapping* from the node's current store, then the node is permanently deleted
When nodes have been archived, they contain all the details of the original location. Use the restore feature to return a node back to its original store.
Parameters:
nodeRef - reference to a node within a store
Throws:
InvalidNodeRefException - if the reference given is invalid

Retrieve immediate children of a given node where the child nodes are in the given inclusive list.
Parameters:
nodeRef - the parent node - usually a container
childNodeTypeQNames - the types that the children may be. Subtypes are not automatically calculated and the list must therefore be exhaustive.
Returns:
Returns a list of ChildAssociationRef instances.

getChildAssocsByPropertyValue
@Auditable(parameters={
  "nodeRef",
  "propertyQName",
  "value"
})
List<ChildAssociationRefgetChildAssocsByPropertyValue(NodeRef nodeRef,
                                                        QName propertyQName,
                                                        Serializable value)
Retrieve the immediate children of a given node based on the value of a property of those children.

If the property to be searched is multi-valued then will match on any one values.

Please note, the following system maintained properties that cannot be used with this method.

  • cm:name - use getChildByName instead
  • cm:created
  • cm:creator
  • cm:modified
  • cm:modifier
  • sys:node-uuid
  • sys:node-dbid
  • sys:store-identifier
  • sys:store-protocol
Parameters:
nodeRef - the parent node - usually a container
propertyQName - the fully qualified name of the property
value - the value to search for. Must be a simple type such as String, Number, Date or Boolean, it cannot be a collection, a content property, MLText or a float.
Returns:
Returns a list of ChildAssociationRef instances.

getChildByName
@Auditable(parameters={
  "nodeRef",
  "assocTypeQName",
  "childName"
})
NodeRef getChildByName(NodeRef nodeRef,
                       QName assocTypeQName,
                       String childName)
Get the node with the given name within the context of the parent node. The name is case-insensitive as Alfresco has to support case-insensitive clients as standard.

That API method getChildByName only works for associations that don't allow duplicate child names. See cm:folder and the duplicate tag. Child associations without this allow duplicate child names and therefore it is possible to have multiple children with the same name stored against the given association type.

Parameters:
nodeRef - the parent node - usuall a container
assocTypeQName - the type of the association
childName - the name of the node as per the property cm:name
Returns:
Returns the child node or null if not found

  "nodeRef",
  "assocTypeQName",
  "childName"
})
List<ChildAssociationRefgetChildrenByName(NodeRef nodeRef,
                                            QName assocTypeQName,
                                            Collection<String> childNames)
Get the nodes with the given names within the context of the parent node.
Parameters:
childNames - a collection of up to 1000 child names to match on
See Also:
getChildByName(NodeRef, QName, String)

getPrimaryParent
@Auditable(parameters="nodeRef")
ChildAssociationRef getPrimaryParent(NodeRef nodeRef)
                              throws InvalidNodeRefException

                                                                        QName assocTypeQName)
