def checkPos(nonOverlapping: Boolean)(using Context): Unit

Check that all positioned items in this tree satisfy the following conditions:

Check that all positioned items in this tree satisfy the following conditions:

  • Parent spans contain child spans
  • If item is a non-empty tree, it has a position

Attributes

def cloneIn(src: SourceFile): this.type

Clone this node but assign it a fresh id which marks it as a node in file.

Clone this node but assign it a fresh id which marks it as a node in file.

Attributes

def envelope(src: SourceFile, startSpan: Span): Span

The union of startSpan and the spans of all positioned children that have the same source as this node, except that Inlined nodes only consider their call child.

The union of startSpan and the spans of all positioned children that have the same source as this node, except that Inlined nodes only consider their call child.

Side effect: Any descendants without spans have but with the same source as this node have their span set to the end position of the envelope of all children to the left, or, if that one does not exist, to the start position of the envelope of all children to the right.

Attributes

def span: Span

The span part of the item's position

The span part of the item's position

def span_=(span: Span): Unit
final def srcPos: SrcPos

This positioned item, widened to SrcPos. Used to make clear we only need the position, typically for error reporting.

Attributes

def uniqueId: Int

A unique identifier in case -Yshow-tree-ids, or -Ydebug-tree-with-id is set, -1 otherwise.

Attributes

def withSpan(span: Span): this.type

A positioned item like this one with given span. 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.
