Example 1 with ImmutableSet

use of com.datastax.oss.driver.shaded.guava.common.collect.ImmutableSet in project java-driver by datastax.

the class DefaultTopologyMonitor method nodeInfoBuilder.

/**
 * Creates a {@link DefaultNodeInfo.Builder} instance from the given row.
 *
 * @param broadcastRpcAddress this is a parameter only because we already have it when we come
 *     from {@link #findInPeers(AdminResult, InetSocketAddress, EndPoint)}. Callers that don't
 *     already have it can use {@link #getBroadcastRpcAddress}. For the control host, this can be
 *     null; if this node is a peer however, this cannot be null, since we use that address to
 *     create the node's endpoint. Callers can use {@link #isPeerValid(AdminRow)} to check that
 *     before calling this method.
 * @param localEndPoint the control node endpoint that was used to query the node's system tables.
 *     This is a parameter because it would be racy to call {@code
 *     controlConnection.channel().getEndPoint()} from within this method, as the control
 *     connection may have changed its channel since. So this parameter must be provided by the
 *     caller.
