Method Detail

findNode

public static <T extends StoreTreeNode<T>> Optional<T> findNode(T tree,
                                                                YangInstanceIdentifier path)

Finds a node in tree.

Type Parameters:

T - Store tree node type.

Parameters:

tree - Data Tree

path - Path to the node

Returns:

Optional with node if the node is present in tree, Optional.empty() otherwise.

findNodeChecked

public static <T extends StoreTreeNode<T>> T findNodeChecked(T tree,
                                                             YangInstanceIdentifier path)

findClosest

public static <T extends StoreTreeNode<T>> Map.Entry<YangInstanceIdentifier,T> findClosest(T tree,
                                                                                           YangInstanceIdentifier path)

Finds a node or closest parent in the tree.

Type Parameters:

T - Store tree node type.

Parameters:

tree - Data Tree

path - Path to the node

Returns:

Map.Entry Entry with key which is path to closest parent and value is parent node.

findClosestsOrFirstMatch

public static <T extends StoreTreeNode<T>> Map.Entry<YangInstanceIdentifier,T> findClosestsOrFirstMatch(T tree,
                                                                                                        YangInstanceIdentifier path,
                                                                                                        Predicate<T> predicate)

getChild

public static <T extends StoreTreeNode<T>> Optional<T> getChild(Optional<T> parent,
                                                                YangInstanceIdentifier.PathArgument child)
