AbstractHierarchicalLayoutParameters.rootNode property
Optional. Defines the node/group to use as the root of the tree. This may be provided either as a node/group id or as a node/group object. If this parameter is not specified and multipleRoots is not false then the layout uses the result(s) of the getRootNode
function; otherwise it uses the first node/group found in the dataset.
