A node in the query AST.
Every Node has a number of child nodes and an optional type annotation.

All child nodes of this node.
All child nodes of this node. Must be implemented by subclasses.

def
nodeRebuild(ch: IndexedSeq[Node]): Self
Rebuild this node with a new list of children.
Rebuild this node with a new list of children. Implementations of this method *must not* perform any optimization to reuse the current node. This method always returns a fresh copy.

Apply a mapping function to all children of this node and recreate the node with the new children.
Apply a mapping function to all children of this node and recreate the node with the new children. If all new children are identical to the old ones, this node is returned. If
is set to true, the type of this node is kept even if the children have changed.keepType

Return this Node with a Type assigned.
Return this Node with a Type assigned. This may only be called on freshly constructed nodes with no other existing references, i.e. creating the Node plus assigning it a Type must be atomic.

Rebuild this node and all children with their computed type.
Rebuild this node and all children with their computed type. If this node already has a type, the children are only type-checked again if
is set to true. iftypeChildren
is also set to true, the existing type of this node is replaced. If this node does not yet have a type, the types of all children are computed.retype
