代码优化.有效使用内存
可以考虑对循环进行优化,避免无用的迭代和条件判断。
```
class MemoryManager:
def __init__(self, allocator):
self.allocator = allocator
def allocate(self, process, request_size):
memory_view = self.allocator.memory_view()
block_start = None
for i, block in enumerate(memory_view):
if block is None:
if block_start is None:
block_start = i
if i - block_start + 1 == request_size:
self.allocator.allocate_memory(block_start, request_size, process)
return block_start
else:
block_start = None
return None
```
在这个优化版本中,当找到一个可用的内存块时,只需要检查是否满足请求的大小,如果满足则立即进行分配并返回结果;否则继续搜索下一个内存块。这样可以避免不必要的迭代和条件判断。
