Example 1 with NodeAttributeView

use of org.apache.ignite.spi.systemview.view.NodeAttributeView in project ignite by apache.

the class GridDiscoveryManager method nodeAttributeViewSupplier.

/**
 * Node attributes view supplier.
 *
 * @param filter Filter.
 */
private Iterable<NodeAttributeView> nodeAttributeViewSupplier(Map<String, Object> filter) {
    Object nodeFilter = filter.get(NodeAttributeViewWalker.NODE_ID_FILTER);

        nodeId = (UUID) nodeFilter;
    else if (nodeFilter instanceof String) {
        try {
            nodeId = UUID.fromString((String) nodeFilter);
        } catch (RuntimeException ignored) {

    } else if (nodeFilter != null)
        return Collections.emptyList();

            nodes = Collections.singleton(node);
        else
            nodes = Collections.emptySet();
    } else
        nodes = F.concat(false, allNodes(), daemonNodes());
    String attrName = (String) filter.get(NodeAttributeViewWalker.NAME_FILTER);
    return F.flat(F.iterator(nodes, node -> {
        Map<String, Object> attrs = node.attributes();
        if (attrName != null) {
            Object attrVal = attrs.get(attrName);
            if (attrVal == null)
                return Collections.emptyList();
            attrs = F.asMap(attrName, attrs.get(attrName));
        }
        return F.iterator(attrs.entrySet(), na -> new NodeAttributeView(node.id(), na.getKey(), na.getValue()), true);
    }, true));
}

Example 2 with NodeAttributeView

use of org.apache.ignite.spi.systemview.view.NodeAttributeView in project ignite by apache.

the class SystemViewSelfTest method testNodeAttributes.
