示例1: trackNewWorkUnit
import java.util.ArrayDeque; //導入方法依賴的package包/類
/**
* Store dependency tables for later retrieval by the EE.
* @param workunit
*/
void trackNewWorkUnit(final Map<Integer, List<VoltTable>> dependencies) {
for (final Entry<Integer, List<VoltTable>> e : dependencies.entrySet()) {
// could do this optionally - debug only.
if (debug.val) verifyDependencySanity(e.getKey(), e.getValue());
// create a new list of references to the workunit's table
// to avoid any changes to the WorkUnit's list. But do not
// copy the table data.
ArrayDeque<VoltTable> deque = m_depsById.get(e.getKey());
if (deque == null) {
deque = new ArrayDeque<VoltTable>();
// intentionally overwrite the previous dependency id.
// would a lookup and a clear() be faster?
m_depsById.put(e.getKey(), deque);
} else {
deque.clear();
}
for (VoltTable vt : e.getValue()) {
if (vt != null) deque.add(vt);
} // FOR
}
if (debug.val) LOG.debug("Current InputDepencies:\n" + StringUtil.formatMaps(m_depsById));
}
