示例1: __setitem__
# 需要導入模塊: from collections import MutableMapping [as 別名]
# 或者: from collections.MutableMapping import get [as 別名]
def __setitem__(self, key, value):
evicted_value = _Null
with self.lock:
# Possibly evict the existing value of 'key'
evicted_value = self._container.get(key, _Null)
self._container[key] = value
# If we didn't evict an existing value, we might have to evict the
# least recently used item from the beginning of the container.
if len(self._container) > self._maxsize:
_key, evicted_value = self._container.popitem(last=False)
if self.dispose_func and evicted_value is not _Null:
