Class NavNodeChildLoador<T,​O,​M,​B extends NavBridge<M,​N>,​N extends NavNode<M,​N>>

java.lang.Object
jaxx.runtime.swing.nav.NavNodeChildLoador<T,​O,​M,​B,​N>
Type Parameters:
T - type of data used to create nodes (can be just a String type to use only ids)
O - type of data associated with nodes
N - type of node to used (to make possible full co-variance and no cast in fal implementations).
All Implemented Interfaces:
java.io.Serializable
Direct Known Subclasses:
NavTreeNodeChildLoador, NavTreeTableNodeChildLoador
public abstract class NavNodeChildLoador<T,​O,​M,​B extends NavBridge<M,​N>,​N extends NavNode<M,​N>>
extends java.lang.Object
implements java.io.Serializable
Object to load childs of a node. It uses NavDataProvider in method loadChilds(NavBridge, NavNode, NavDataProvider) to obtain datas then build childs nodes. A factory of such objects can be found in NavHelper to make them reusable in other places than inside a NavNode to auto-load childs. For example when you want to creat by hand a new node, always prefer to reuse a such object rathen than duplicate same code in helper...

      parentId - id of parent
      dataProvider - the data provider
      Returns:
      the list of data
      Throws:
      java.lang.Exception - if any problem

      Parameters:
      data - the data of the node to create
      dataProvider - the data provider
      Returns:
      the created node

    • getBeanType

      public java.lang.Class<O> getBeanType()
      Returns the type of data associated with nodes to create.
      Returns:
      the type of data associated with created nodes.

    • loadChilds

      public void loadChilds​(B bridge, N parentNode, NavDataProvider dataProvider) throws java.lang.Exception
      Load childs of the given parentnode.
      Parameters:
      bridge - the model owner of nodes
      parentNode - the parent node where to insert nodes
      dataProvider - data provider
      Throws:
      java.lang.Exception - pour tout probleme de recuperation de donnees

    • addChildNodes

      protected void addChildNodes​(N parentNode, java.util.List<T> datas, NavDataProvider dataProvider)
      Add childs to given parentNode using retrive datas from the data provider. This method is invoked by the loadChilds(NavBridge, NavNode, NavDataProvider).
      Parameters:
      parentNode - the node where to insert
