Edge
(root, parent, child, tag=None, attrib=None)[source]¶ Bases:
object
Labeled edge between two
Node
objects in UCCA annotation graph.An edge between Nodes in a
Passage
is a simple object; it is a directed edge whose ID is derived by the parent and child of the edge, it is mostly immutable except for its attributes, and it is labeled with the connection type between the Nodes. An edge can have multiple annotations, representing connection types of one or more layers.- Attributes:
ID: ID of the Edge, constructed from the IDs of the two Nodes root: the Passage this object is linked with attrib: attribute dictionary of the Edge extra: temporary storage space for undocumented attributes and data tag: the string label of the Edge parent: the originating Node of the Edge child: the target Node of the Edge categories: a list of categories for this edge ID_FORMAT: format string which creates the ID of the Edge from
the IDs of the parent (first argument to the formatting string) and the child (second argument).

equals
(other, *, recursive=True, ordered=False, ignore_node=None, ignore_edge=None)[source]¶ Returns whether self and other are Edge-equals.
Edge-equality is determined by having the same tag and attributes. Recursive Edge-equality means that the Edges are equal, and their children are recursively Node-equal.
Parameters: - other – an Edge object to compare to
- recursive – whether to compare recursively, defaults to True
- ordered – if recursive, whether the children are Node-equivalent w.r.t order (see Node.equals())
- ignore_node – function that returns whether to ignore a given node
- ignore_edge – function that returns whether to ignore a given edge
Returns: True iff the Edges are equal.
