    • Method Detail

      • getPartitionEnumeration

        @Pure
public Class<? extends Enum<?>> getPartitionEnumeration()
        Description copied from interface: TreeNode
        Replies the enumeration type that is defining the children of the nodes.
        Returns:
        the enumeration type of the child partition, or null if no such enumeration type is defined.

      • clear

        public void clear()
        Clear the tree.

        Caution: this method also destroyes the links between the child nodes inside the tree. If you want to unlink the first-level child node with this node but leave the rest of the tree unchanged, please call setChildAt(i,null).

      • getNotNullChildCount

        @Pure
public int getNotNullChildCount()
        Description copied from interface: IterableNode
        Replies count of not-null children in this node.

        The number of not-null children is lower or equal to the value replied by IterableNode.getChildCount().

        Returns:
        the count of not-null children.
        See Also:
        IterableNode.getChildCount()

      • getChildAt

        @Pure
public N getChildAt​(int index)
             throws IndexOutOfBoundsException
        Description copied from interface: IterableNode
        Replies the n-th child in this node.
        Parameters:
        index - is the index of the child to reply
        Returns:
        the child node.
        Throws:
        IndexOutOfBoundsException - if the given index was invalid

      • isLeaf

        @Pure
public boolean isLeaf()
        Description copied from interface: IterableNode
        Replies if this node is a leaf.
        Returns:
        true is this node is a leaf, otherwise false

      • moveTo

        public boolean moveTo​(N newParent,
                      int index)
        Description copied from interface: TreeNode
        Move this node in the given new node.

        If any child node is already present at the given position in the new parent node, the tree node may replace the existing node or insert the moving node according to its implementation.

        This function is preferred to a sequence of calls to IterableNode.removeFromParent() and TreeNode.setChildAt(int, TreeNode) because it fires a limited set of events dedicated to the move the node.

        Parameters:
        newParent - is the new parent for this node.
        index - is the position of this node in the new parent.
        Returns:
        true on success, otherwise false.

      • removeChild

        public boolean removeChild​(N child)
        Description copied from interface: TreeNode
        Remove the specified node from this node if it is a child.
        Parameters:
        child - is the child to remove.
        Returns:
        true if the node was removed, otherwise false

      • indexOf

        @Pure
public int indexOf​(N child)
        Description copied from interface: TreeNode
        Replies the index of the specified child.
        Parameters:
        child - is the node to search for.
        Returns:
        the index or -1.

      • getChildren

        public void getChildren​(Object[] array)
        Description copied from interface: TreeNode
        Replies the child nodes of this node.

        This function may put null in the array cells if the current tree node has not a child at the corresponding index.

        Parameters:
        array - is the array to fill.
        See Also:
        TreeNode.getChildren(Class), TreeNode.children()
