Properties

allExpanded source

Whether every node eligible for expansion is expanded.

This is a readable and writable property. Setting to true causes all nodes to be expanded.

childrenPath source

An FRB expression, that evaluated against content or any of its children, produces an array of that content's children. By default, this is simply "children", but for an alternate example, a binary tree would have children [left, right], except that said tree would need to have no children if left and right were both null, so (left ?? []).concat(right ?? []), to avoid infinite recursion.

This property must be set before content.

constructor source

Creates a tree controller.

content source

The input of a tree controller, an object to serve at the root of the tree.

findNodeByContent source

Finds and returns the node having the given content. Takes an optional second argument to specify the compare function to use. note: If you are doing find operations frequently, it might be better to attach a binding that will facilitate incremental updates and O(1) lookups. nodeForContent <- nodes{[content, this]}.toMap()

initiallyExpanded source

Whether nodes of the tree are initially expanded.

This property must be set before content. If content has already set, use allExpanded.

iterations source

The product of a tree controller, an array of tree controller nodes corresponding to each branch of the content for which every parent node is expanded.

Node :TreeControllerNode source

noneExpanded source

Whether any nodes are collapsed.

This is a readable and writable property. Setting to true causes all nodes to be collapsed.

postOrderWalk source

Performs a traversal of the tree, executes the callback function for each node. The callback is called after continuing the walk on its children.

preOrderWalk source

Performs a traversal of the tree, executes the callback function for each node. The callback is called before continuing the walk on its children.

root source

A by-product of the tree controller, the root node of the tree for the current content.
