示例1: getErrorRecoverySet
# 需要導入模塊: from antlr4.IntervalSet import IntervalSet [as 別名]
# 或者: from antlr4.IntervalSet.IntervalSet import removeOne [as 別名]
def getErrorRecoverySet(self, recognizer:Parser):
atn = recognizer._interp.atn
ctx = recognizer._ctx
recoverSet = IntervalSet()
while ctx is not None and ctx.invokingState>=0:
# compute what follows who invoked us
invokingState = atn.states[ctx.invokingState]
rt = invokingState.transitions[0]
follow = atn.nextTokens(rt.followState)
recoverSet.addSet(follow)
ctx = ctx.parentCtx
recoverSet.removeOne(Token.EPSILON)
return recoverSet示例2: getExpectedTokens
# 需要導入模塊: from antlr4.IntervalSet import IntervalSet [as 別名]
# 或者: from antlr4.IntervalSet.IntervalSet import removeOne [as 別名]
