示例1: open
import org.apache.cassandra.config.Schema; //导入方法依赖的package包/类
private static Keyspace open(String keyspaceName, Schema schema, boolean loadSSTables)
{
Keyspace keyspaceInstance = schema.getKeyspaceInstance(keyspaceName);
if (keyspaceInstance == null)
{
// instantiate the Keyspace. we could use putIfAbsent but it's important to making sure it is only done once
// per keyspace, so we synchronize and re-check before doing it.
synchronized (Keyspace.class)
{
keyspaceInstance = schema.getKeyspaceInstance(keyspaceName);
if (keyspaceInstance == null)
{
// open and store the keyspace
keyspaceInstance = new Keyspace(keyspaceName, loadSSTables);
schema.storeKeyspaceInstance(keyspaceInstance);
// keyspace has to be constructed and in the cache before cacheRow can be called
for (ColumnFamilyStore cfs : keyspaceInstance.getColumnFamilyStores())
cfs.initRowCache();
}
}
}
return keyspaceInstance;
