示例1: __init__
def __init__(self, span, lhs, rhs, dot=0, bindings=None):
"""
Construct a new edge. If the edge is incomplete (i.e., if
``dot<len(rhs)``), then store the bindings as-is. If the edge
is complete (i.e., if ``dot==len(rhs)``), then apply the
bindings to all nonterminals in ``lhs`` and ``rhs``, and then
clear the bindings. See ``TreeEdge`` for a description of
the other arguments.
"""

# and then throw them away. (If we didn't throw them away, we
# might think that 2 complete edges are different just because

# already been applied.)
