Concrete methods
The reverse path from any node in from
to the node that closest encloses span
, or Nil
if no such path exists. If a non-empty path is returned it starts with the node closest enclosing span
and ends with one of the nodes in from
.
The reverse path from any node in from
to the node that closest encloses span
, or Nil
if no such path exists. If a non-empty path is returned it starts with the node closest enclosing span
and ends with one of the nodes in from
.
Value parameters
- skipZeroExtent
-
If true, skip over zero-extent nodes in the search. These nodes do not correspond to code the user wrote since their start and end point are the same, so this is useful when trying to reconcile nodes with source code.
Attributes
The untyped tree corresponding to typed tree tree
in the compilation unit specified by ctx
The untyped tree corresponding to typed tree tree
in the compilation unit specified by ctx
Attributes
The reverse path of untyped trees starting with a tree that closest matches tree
and ending in the untyped tree at the root of the compilation unit specified by ctx
.
The reverse path of untyped trees starting with a tree that closest matches tree
and ending in the untyped tree at the root of the compilation unit specified by ctx
.
Value parameters
- exactMatch
-
If
true
, the path must start with a node that exactly matchestree
, orNil
is returned. Iffalse
the path might start with a node enclosing the logical position oftree
. Note: A complication concerns member definitions. ValDefs and DefDefs have after desugaring a position that spans just the name of the symbol being defined and nothing else. So we look instead for an untyped tree approximating the envelope of the definition, and declare success if we find another DefTree.
Attributes
The reverse part of the untyped root of the compilation unit of ctx
to the given span
.
