Emit when the children of the given node are refreshed.
Emitted when the selection has changed in the tree.
A root node of this tree. Undefined if there is no root node. Setting a root node refreshes the tree.
A root node of this tree. Undefined if there is no root node. Setting a root node refreshes the tree.
The tree selection, representing the selected nodes from the tree. If nothing is selected, the result will be empty.
Registers the given selection into the tree selection service. If the selection state changes after adding the
selectionOrTreeNode argument, a selection changed event will be fired. If the argument is a tree node,
a it will be treated as a tree selection with the default selection type.
Collapses recursively. If the node argument is undefined, then collapses the currently selected tree node.
If multiple tree nodes are selected, collapses the most recently selected tree node.
Optional raw: Readonly<CompositeTreeNode>Collapses the given node. If the node argument is undefined, then collapses the currently selected tree node.
If multiple tree nodes are selected, collapses the most recently selected tree node.

Returns the previous selectable tree node.
Protected handleProtected initProtected isMarks the give node as busy after a specified number of milliseconds. A token source of the given token should be canceled to unmark.
Navigates to the given node if it is defined. This method accepts both the tree node and its ID as an argument.
Navigation sets a node as a root node and expand it. Resolves to the node if the navigation was successful. Otherwise,
resolves to undefined.
Opens the given node or the currently selected on if the argument is undefined.
If multiple nodes are selected, open the most recently selected node.
Optional raw: TreeNodeRefresh children of the root node.
Return a valid refreshed composite root or undefined if such does not exist.
Optional parent: Readonly<CompositeTreeNode>Protected selectSelect the given node if it is the ancestor of a selected node.
Selects the next node relatively to the currently selected one. This method takes the expansion state of the tree into consideration.
Selects the given tree node. Has no effect when the node does not exist in the tree. Discards any previous selection state.
Protected selectSelects the previous node relatively to the currently selected one. This method takes the expansion state of the tree into consideration.
Selects a range of tree nodes. The target of the selection range is the argument, the from tree node is the previous selected node. If no node was selected previously, invoking this method does nothing.
Selects the given node if it was not yet selected, or unselects it if it was. Keeps the previous selection state and updates it with the current toggle selection.
Toggles the expansion state of the given node. If not give, then it toggles the expansion state of the currently selected node. If multiple nodes are selected, then the most recently selected tree node's expansion state will be toggled.
