      • getChild

        public Object getChild​(Object parent,
                               int index)
        Returns the child of parent at index index in the parent's child array. parent must be a node previously obtained from this data source. This should not return null if index is a valid index for parent (that is index >= 0 && index < getChildCount(parent)).
        Specified by:
        getChild in interface TreeModel
        Overrides:
        getChild in class DefaultTreeModel
        Parameters:
        parent - a node in the tree, obtained from this data source
        Returns:
        the child of parent at index index
      • getChildCount

        public int getChildCount​(Object parent)
        Returns the number of children of parent. Returns 0 if the node is a leaf or if it has no children. parent must be a node previously obtained from this data source.
        Specified by:
        getChildCount in interface TreeModel
        Overrides:
        getChildCount in class DefaultTreeModel
        Parameters:
        parent - a node in the tree, obtained from this data source
        Returns:
        the number of children of the node parent
      • getIndexOfChild

        public int getIndexOfChild​(Object parent,
                                   Object child)
        Returns the index of child in parent. If parent is null or child is null, returns -1.
        Specified by:
        getIndexOfChild in interface TreeModel
        Overrides:
        getIndexOfChild in class DefaultTreeModel
        Parameters:
        parent - a note in the tree, obtained from this data source
        child - the node we are interested in
        Returns:
        the index of the child in the parent, or -1 if either child or parent are null
      • getRoot

        public Object getRoot()
        Returns the root of the tree. Returns null only if the tree has no nodes.
        Specified by:
        getRoot in interface TreeModel
        Overrides:
        getRoot in class DefaultTreeModel
        Returns:
        the root of the tree
      • isLeaf

        public boolean isLeaf​(Object node)
        Returns true if node is a leaf. It is possible for this method to return false even if node has no children. A directory in a filesystem, for example, may contain no files; the node representing the directory is not a leaf, but it also has no children.
        Specified by:
        isLeaf in interface TreeModel
        Overrides:
        isLeaf in class DefaultTreeModel
        Parameters:
        node - a node in the tree, obtained from this data source
        Returns:
        true if node is a leaf
