示例1: test_WeakStrongRefCallbacks
# 需要导入模块: from pxr import Tf [as 别名]
# 或者: from pxr.Tf import _callUnboundInstance [as 别名]
def test_WeakStrongRefCallbacks(self):
class Foo(object):
def method(self):
return 'python method'
f = Foo()
m = f.method
# the callback is an instancemethod, it should not keep the object
# alive.
Tf._setTestCallback(m)
self.assertEqual('python method', Tf._invokeTestCallback())
del f
del m
print 'expected warning...'
self.assertEqual('', Tf._invokeTestCallback())
print 'end of expected warning'
l = lambda : 'python lambda'
# the callback is a lambda, it should stay alive (and will keep f alive)
Tf._setTestCallback(l)
self.assertEqual('python lambda', Tf._invokeTestCallback())
del l
self.assertEqual('python lambda', Tf._invokeTestCallback())
# Test unbound instance method.
self.assertEqual('test', Tf._callUnboundInstance(str.lower, "TEST"))
# the callback is a function, it should not stay alive
