buffer empty

基本解釋

The UNION operation repeats this step until the SHIP buffer is empty.
UNION 操作符重復這個步驟，直到 SHIP 緩沖區(qū)為空。
InfiniteBuffer, which also provides a FIFO semantics, except that only readers can be blocked if the buffer is empty.
也提供先進先出語義，但是如果緩沖為空，那么可以將閱讀器阻塞。
When the SHIP buffer is empty, the SHIP logic sends another 'Fetch' request to the "US" server to get the next block of data.
當 SHIP 緩沖區(qū)為空時，SHIP 邏輯將另一個 'Fetch' 請求發(fā)送到 "US" 服務(wù)器，以便獲取下一塊數(shù)據(jù)。
