Position
¶ Bases:
typing.NamedTuple()
Data class to hold position information of virtual nodes.
line and col are 1-based to match UAST, offset is 0-based.

VirtualNode
(value:str, start:Position, end:Position, *, node:bblfsh.Node=None, y:Optional[Tuple[int, ...]]=None, is_accumulated_indentation:bool=False, path:str=None)¶ Represent either a real UAST node or an imaginary token.
The class instance should be considered as read-only.

is_labeled_on_lines
(self, lines:Optional[Set[int]])¶ Return true for labeled VirtualNode instance that located on specified lines.
Parameters: lines – list of lines or None. None is considered as all possible lines. Returns: Condition value

from_node
(node:bblfsh.Node, file:str, path:str, token_unwrappers:Mapping[str, Callable[[str], Tuple[str, str]]])¶ Initialize the VirtualNode from a UAST node. Takes into account prefixes and suffixes.
Parameters: - node – UAST node.
- file – File contents.
- path – File path.
- token_unwrappers – Mapping from bblfsh internal types to functions to unwrap tokens.
Returns: New VirtualNode-s.
