Class JcrItemModel<T extends javax.jcr.Item>

java.lang.Object

org.apache.wicket.model.LoadableDetachableModel<T>

org.hippoecm.frontend.model.JcrItemModel<T>

All Implemented Interfaces:

Serializable, org.apache.wicket.model.IDetachable, org.apache.wicket.model.IModel<T>, org.apache.wicket.util.io.IClusterable

public class JcrItemModel<T extends javax.jcr.Item>
extends org.apache.wicket.model.LoadableDetachableModel<T>

Model for JCR Items. The model tracks the Item as well as it can, using the first referenceable ancestor plus a relative path as the identification/retrieval method. When the Item (or one of its ancestors) is moved, this is transparent.

In development, when the model is serialized, it checks whether it has been detached properly.

Method Detail

getUuid

public String getUuid()

Retrieve the identifier (UUID) of the first referencable ancestor node

Returns:

the UUID

getRelativePath

public String getRelativePath()

Retrieve the JCR path for the Item, relative to the first referencable ancestor

Returns:

the relative path

getPath

public String getPath()

The absolute JCR path for the Item.

Returns:

the absolute path

exists

public boolean exists()

Determine whether the Item exists. This will retrieve the Item from the repository. If the Item has been loaded in this request cycle (e.g. using IModel.getObject()), but has since been removed, the returned information may be incorrect.

Returns:

true when the Item exists

getParentModel

public JcrItemModel<javax.jcr.Node> getParentModel()

Retrieve the JcrItemModel for the parent Node.

Returns:

the parent JcrItemModel
