# 或者: from pandas.core.base.FrozenNDArray import copy [as 别名]
class TestFrozenNDArray(CheckImmutable, CheckStringMixin, tm.TestCase):

unicode_container = FrozenNDArray([u("\u05d0"), u("\u05d1"), "c"])

self.assertIsInstance(self.container.view(), FrozenNDArray)
self.assertFalse(isinstance(
self.container.view(np.ndarray), FrozenNDArray))

# shallow copy should be the same too
