TreeNode
Reference an attribute or function that can be applied to this node.
Reference an attribute or function that can be applied to this node.
this->attribute is equivalent to attribute(this).
The attribute definition is defined on a type T other than that of the
node to which it is applied (this.type). An implicit value must exist
to transform from the node type to the type expected by the attribute.
This form of attribute reference is commonly used to implement attribute
forwarding where the implicit parameter enables references to the attribute
to be implicitly forwarded to some other node.

This node's Attributable children in left-to-right order.
This node's Attributable children in left-to-right order. Children
that are not Attributable are ignored, except for nodes that collect
Attributable children. Those indirect children are also collected
here.

This node's first Attributable child.
This node's first Attributable child.
Raises an IndexOutOfBounds exception if this node has no such children.

The index of this node as a child of its parent or -1 if this node has no parent (i.e., it's a root).

House-keeping method to connect this node's children to it and their siblings (and recursively through the subtree rooted here).
House-keeping method to connect this node's children to it and their
siblings (and recursively through the subtree rooted here). The easy
case is Attributable children that are direct descendants.
Also connected are Attributable descendants that are reachable via
a path of descendants that only passes through GenTraversable, Some,
or tuple (up to size four) nodes. Thus, descendants of these kinds
are regarded as children for the purposes of attribution. As a
side-effect, this method remembers the children so that they can be
accessed easily via the children iterator.

a T-specific operation is applied to the next, which otherwise
would be of type Attributable.

A link to the parent Attributable node of this node or null if
this node has no parent.
A link to the parent Attributable node of this node or null if
this node has no parent. Note that this link will skip intervening
non-Attributable ancestors.

General behaviour for tree nodes. Case classes that implement actual tree node types should mix-in this trait.
