Example 1 with MycatNode

use of io.mycat.config.MycatNode in project Mycat-Server by MyCATApache.

the class ShowMyCATCluster method getRows.

private static List<RowDataPacket> getRows(ServerConnection c) {
    List<RowDataPacket> rows = new LinkedList<RowDataPacket>();
    MycatConfig config = MycatServer.getInstance().getConfig();
    MycatCluster cluster = config.getCluster();
    Map<String, SchemaConfig> schemas = config.getSchemas();
    SchemaConfig schema = (c.getSchema() == null) ? null : schemas.get(c.getSchema());
    // 如果没有指定schema或者schema为null，则使用全部集群。
    if (schema == null) {
        Map<String, MycatNode> nodes = cluster.getNodes();
        for (MycatNode n : nodes.values()) {
            if (n != null && n.isOnline()) {
                rows.add(getRow(n, c.getCharset()));
            }
        }
    } else {
        Map<String, MycatNode> nodes = cluster.getNodes();
        for (MycatNode n : nodes.values()) {

                rows.add(getRow(n, c.getCharset()));
            }
        }
