Does the tree have its type field set? Note: this operation is not referentially transparent, because it can observe the withType modifications.
Does the tree have its type field set? Note: this operation is not referentially transparent, because it can observe the withType modifications. Should be used only in special circumstances (we need it for printing trees with optional type info).
The initial, synthetic position.
The initial, synthetic position. This is usually the union of all positioned children's positions.
Does this tree define a new symbol that is not defined elsewhere?
Is this tree either the empty tree or the empty ValDef?

The position of the name defined by this definition.
The position of the name defined by this definition.
This is a point position if the definition is synthetic, or a range position
if the definition comes from source.
It might also be that the definition does not have a position (for instance when synthesized by
a calling chain from viewExists
), in that case the return position is NoPosition.

The item's position.

Optionally, the old attachment with given key
if one existed before.
The new attachment is added at the position of the old one, or at the end
if no attachment with same key
existed.
Remove attachment with given key
, if it exists.
Remove attachment with given key
, if it exists.
Optionally, the removed attachment with given key
if one existed before.
Destructively update curPos
to given position.
Destructively update curPos
to given position. Also, set any missing
positions in children.
The string representation of this showable element.
The string representation of this showable element.
The summarized string representation of this showable element.
The summarized string representation of this showable element. Recursion depth is limited to some smallish value. Default is Config.summarizeDepth.

Convert tree to a list.
Convert tree to a list. Gives a singleton list, except for thickets which return their element trees.
The text representation of this showable element.
The type of the tree.
The type of the tree. In case of an untyped tree, an UnAssignedTypeException is thrown. (Overridden by empty trees)
The number of nodes in this tree
The number of nodes in this tree

A positioned item like this one with the position set to pos
.
A positioned item like this one with the position set to pos
.
if the positioned item is source-derived, a clone is returned.
If the positioned item is synthetic, the position is updated
destructively and the item itself is returned.
Return a typed tree that's isomorphic to this tree, but has given type.
