Method Detail

values

public static IgniteFeatures[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (IgniteFeatures c : IgniteFeatures.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IgniteFeatures valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getFeatureId

public int getFeatureId()

Returns:

Feature ID.

nodeSupports

public static boolean nodeSupports(ClusterNode clusterNode,
                                   IgniteFeatures feature)

Checks that feature supported by node.

Parameters:

nodeSupports

public static boolean nodeSupports(byte[] featuresAttrBytes,
                                   IgniteFeatures feature)

Checks that feature supported by node.

Parameters:

featuresAttrBytes - Byte array value of supported features node attribute.

feature - Feature to check.

Returns:

True if feature is declared to be supported by remote node.

allNodesSupports

public static boolean allNodesSupports(Iterable<ClusterNode> nodes,
                                       IgniteFeatures feature)

Checks that feature supported by all nodes.

Parameters:

nodes - cluster nodes to check their feature support.

Returns:
