Method Detail

nodeId

UUID nodeId()

Gets ID of a remote node.

Returns:

Node ID.

consistentId

Object consistentId()

Gets consistent globally unique node ID. Unlike nodeId() method, this method returns consistent node ID which survives node restarts.

Returns:

Consistent globally unique node ID.

tcpAddresses

List<String> tcpAddresses()

Gets list of REST TCP server addresses of remote node.

Returns:

REST TCP server addresses.

tcpHostNames

List<String> tcpHostNames()

Gets list of REST TCP server host names of remote node.

Returns:

REST TCP server host names.

tcpPort

int tcpPort()

Gets client TCP port of remote node.

Returns:

Remote tcp port.

attributes

Map<String,Object> attributes()

Gets all attributes of remote node. Note that all system and environment properties are automatically includes in node attributes. User can also attach custom attributes and then use them to further filter remote nodes into virtual subgrids for task execution.

Returns:

All node attributes.

attribute

@Nullable
<T> T attribute(String name)

Gets specific attribute of remote node.

Parameters:

name - Attribute name.

Returns:

Attribute value.

attributes()

metrics

GridClientNodeMetrics metrics()

Gets various dynamic metrics of remote node.

Returns:

Metrics of remote node.

caches

Map<String,GridClientCacheMode> caches()

Gets all configured caches and their types on remote node.

Returns:

Map in which key is a configured cache name on the node, value is mode of configured cache.

availableAddresses

Collection<InetSocketAddress> availableAddresses(GridClientProtocol proto,
                                                 boolean filterResolved)

Gets collection of addresses on which REST binary protocol is bound.

Parameters:

proto - Protocol for which addresses are obtained.

filterResolved - Whether to filter resolved addresses ( InetSocketAddress.isUnresolved() returns False ) or not.

Returns:

List of addresses.

connectable

boolean connectable()

Indicates whether client can establish direct connection with this node. So it is guaranteed that that any request will take only one network 'hop' before it will be processed by a Grid node.

Returns:

true if node can be directly connected, false if request may be passed through a router.

order

long order()

Node order within grid topology.

Returns:

Node startup order.
