      org.exoplatform.services.jcr.ext.distribution.impl.DataDistributionByName

All Implemented Interfaces:

DataDistributionType

public class DataDistributionByName
extends AbstractDataDistributionType

This data distribution will distribute the data in a understandable way for a human being. The expected data id is for example a login of a user. It will generate a hierarchy of sub-nodes with n levels of depth for example with n = 4:

• Usename: john.smith (size >= 4) it will generate a path of type "j___/jo___/joh___/john.smith"
• Usename: bob (size < 4) it will generate a path of type "b___/bo___/bob"

public DataDistributionByName()

Method Detail

getAncestors

protected List<String> getAncestors(String dataId)

Gives the list of all the name of the ancestors

Specified by:

getAncestors in class AbstractDataDistributionType

Parameters:

dataId - the id of the data to find/create

Returns:

the list of the ancestor names

useParametersOnLeafOnly

protected boolean useParametersOnLeafOnly()

Indicates whether or not the node type, the mixin types and the permissions have to be used on leaf node only.

Specified by:

useParametersOnLeafOnly in class AbstractDataDistributionType

Returns:

true if only the leaf node has to be created with the parameters false otherwise.

migrate

public void migrate(javax.jcr.Node rootNode)
             throws javax.jcr.RepositoryException

Migrate from old structure to new one.

Specified by:

migrate in interface DataDistributionType

Overrides:

migrate in class AbstractDataDistributionType

Parameters:

rootNode - the root node under which the data to migrate is stored

Throws:

javax.jcr.RepositoryException - if an error occurred during migration

migrate

public void migrate(javax.jcr.Node rootNode,
                    String nodeType,
                    List<String> mixinTypes,

             throws javax.jcr.RepositoryException

Migrate from old structure to new one.

Specified by:

migrate in interface DataDistributionType

Overrides:

migrate in class AbstractDataDistributionType

Parameters:

rootNode - the root node under which the data to migrate is stored

nodeType - the node type to use in case we need to create the node

mixinTypes - the mixin types to use in case we need to create the node

permissions - the permissions to use in case we need to create the node

Throws:

javax.jcr.RepositoryException - if an error occurred during migration
