  • Method Details

    • isCollapsed

      public boolean isCollapsed(int index)
      Note: The check only works for visible elements, therefore a check for an element that is below an collapsed element does not work.
      Parameters:
      index - The index of the tree element to check.
      Returns:
      true if the children of the tree node at the given index are visible, false if not.

    • collapse

      public List<Integer> collapse(int index)
      Collapse the tree node at the given visible index.
      Parameters:
      index - The index of the node in the collection that should be collapsed.
      Returns:
      Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

    • collapseAll

      public List<Integer> collapseAll()
      Will check the whole TreeList for its nodes and collapses them if they are expanded. After executing this method, all nodes in the TreeList will be collapsed.
      Returns:
      Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

    • expand

      public List<Integer> expand(int index)
      Expand the tree node at the given visible index.
      Parameters:
      index - The index of the node in the collection that should be expanded.
      Returns:
      Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

    • expandToLevel

      public List<Integer> expandToLevel(int parentIndex, int level)
      Description copied from interface: ITreeRowModel
      Expands the tree node at the given index to a certain level.
      Parameters:
      parentIndex - The index of the node in the collection that should be expanded.
      level - The level to which the tree node should be expanded.
      Returns:
      The indexes of all children that are showed after the expand operation is performed.

    • internalExpandToLevel

      protected void internalExpandToLevel(int parentIndex, int level)
      Performs the expand operations iteratively without notifying the listeners while processing.
      Parameters:
      parentIndex - The index of the node in the collection that should be expanded.
      level - The level to which the tree nodes should be expanded.

    • expandAll

      public List<Integer> expandAll()
      Expands all tree nodes.
      Returns:
      Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

    • internalExpandAll

      protected void internalExpandAll()
      Performs the expand operations iteratively without notifying the listeners while processing.

    • expandToLevel

      public List<Integer> expandToLevel(int level)
      Expands all tree nodes to a certain level.
      Parameters:
      level - The level to which the tree nodes should be expanded.
      Returns:
      Returns an empty list because the list transformation for expand/collapse is handled by GlazedLists TreeList.

    • internalExpandToLevel

      protected void internalExpandToLevel(int level)
      Performs the expand operations iteratively without notifying the listeners while processing.
      Parameters:
      level - The level to which the tree nodes should be expanded.

    • getTreeData

      public GlazedListTreeData<T> getTreeData()
      Returns the ITreeData that is backed by this tree row model.
      Overrides:
      getTreeData in class AbstractTreeRowModel<T>
      Returns:
      The ITreeData that is backed by this tree row model.
