protected final NavTreeNodeChildLoador<?,?,N extends NavTreeNode<N>> childLoador

Optional child loador to lazy create childs of the node.

Constructor Detail

NavTreeNode

protected NavTreeNode(String id)

NavTreeNode

public NavTreeNode(Class<?> internalClass,
                   String id,
                   String context,
                   NavTreeNodeChildLoador<?,?,N> childLoador)

Method Detail

getId

public String getId()

Specified by:

getId in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

getContext

public String getContext()

Specified by:

getContext in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

getInternalClass

public Class<?> getInternalClass()

Specified by:

getInternalClass in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

isLoaded

public boolean isLoaded()

Specified by:

isLoaded in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

isDirty

public boolean isDirty()

Specified by:

isDirty in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

isStringNode

public boolean isStringNode()

Description copied from interface: NavNode

Convinient method to known if the node is a String typed.

Specified by:

isStringNode in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Returns:

true if the type of node if

isStaticNode

public boolean isStaticNode()

Description copied from interface: NavNode

To know if the node is static. A static node has no childLoador.

Specified by:

isStaticNode in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Returns:

true when the node is static : says, the node has no childLoador.

getContainerNode

public N getContainerNode()

Description copied from interface: NavNode

Gets the first node form this one to the root which has a none String type.

Specified by:

getContainerNode in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Returns:

the first concrete node type

findNodeById

public N findNodeById(String id,
                      NavBridge<DefaultTreeModel,N> model,
                      NavDataProvider provider)

Description copied from interface: NavNode

Given an id, obtain the child with matching id. If node is NOT loaded, then first loads it (method NavNode.populateChilds(NavBridge, NavDataProvider)) then do search on direct childs of the node recursivly.

Specified by:

findNodeById in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Parameters:

id - the id of the researched node

model - model owner of nodes

provider - data provider

Returns:

the found node or null if not found

getChild

public N getChild(String id,
                  NavBridge<DefaultTreeModel,N> bridge,
                  NavDataProvider provider)

Description copied from interface: NavNode

Given an id, obtain the child with matching id. If node is NOT loaded, then first loads it (method NavNode.populateChilds(NavBridge, NavDataProvider)) then return on direct childs of the node.

Specified by:

getChild in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Parameters:

id - the id of the researched node

bridge - model owner of nodes

provider - data provider

Returns:

the found node or null if not found

setDirty

public void setDirty(boolean dirty)

Description copied from interface: NavNode

Changes the NavNode.isDirty() state. As a side effect, when a renderer will use this node, it will force to reload the render from the NavDataProvider.

Specified by:

setDirty in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Parameters:

dirty - the new dirty value

isLeaf

public boolean isLeaf()

Specified by:

isLeaf in interface TreeNode

Specified by:

isLeaf in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Overrides:

isLeaf in class DefaultMutableTreeNode

public Object getUserObject()

Specified by:

getUserObject in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Overrides:

getUserObject in class DefaultMutableTreeNode

toString

public String toString()

Specified by:

toString in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Overrides:

toString in class DefaultMutableTreeNode

populateNode

                         NavDataProvider provider,
                         boolean populateChilds)

Description copied from interface: NavNode

To populate the node. A side-effect of this method is to set dirty the node (renderer will recompute the render of the node). If populateChilds is set to true, then also populate childs of the node using the given dataProvider.

Specified by:

populateNode in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

Parameters:

model - le delegate modèles content le noeud

provider - le provider de données

populateChilds - un drapeau pour charger aussi les fils du noeud courant

To populate childs of the node (only when a none static node). A side-effect of this method is to set loaded of the node. For a static node, do nothing.

Specified by:

populateChilds in interface NavNode<DefaultTreeModel,N extends NavTreeNode<N>>

bridge - model owner of the node

provider - data provider
