        parent - A node in the tree.
        index - The index of the desired child.
        Returns:
        A node, or null if there is no such child.

      • getChildCount

        public int getChildCount​(java.lang.Object parent)
        Return the number of children of the given parent. This is the number classes and contained entities, filtered by the filter specified by setFilter(), if any has been specified.
        Specified by:
        getChildCount in interface javax.swing.tree.TreeModel
        Overrides:
        getChildCount in class EntityTreeModel
        Parameters:
        parent - A parent node.
        Returns:
        The number of children.

      • getIndexOfChild

        public int getIndexOfChild​(java.lang.Object parent,
                           java.lang.Object child)
        Return the index of the given child within the given parent. If the parent is not contained in the child, return -1.
        Specified by:

        Parameters:
        parent - The parent.
        child - The child.
        Returns:
        The index of the specified child.

      • isLeaf

        public boolean isLeaf​(java.lang.Object object)
        Return true if the object is a leaf node. An object is a leaf node if it has no children that are instances of one of the classes specified by setFilter(), if a filter has been specified.
        Specified by:
        isLeaf in interface javax.swing.tree.TreeModel
        Overrides:
        isLeaf in class EntityTreeModel
        Parameters:
        object - The object.
        Returns:

      • _classes

        protected java.util.List _classes​(java.lang.Object object)
