# 需要导入模块: from pipeline import Pipeline [as 别名]
# 或者: from pipeline.Pipeline import stream [as 别名]
def test_when_consumer_yield_none(self):
pipeline = Pipeline().add(
PipeBuilder().alias("yield_none").consumer(lambda m: m if m == 0 else None).buffer_size(100).number_of_consumer(2)

expected = [0]
actual = [x for x in pipeline.stream(range(100))]
self.assertEquals(expected, actual)示例2: test_one_pipe
# 需要导入模块: from pipeline import Pipeline [as 别名]
