Enum Constant Detail

RING_DESCRIBE

public static final NodeDiscoveryType RING_DESCRIBE

Discover nodes exclusively from doing a ring describe

DISCOVERY_SERVICE

public static final NodeDiscoveryType DISCOVERY_SERVICE

Discover nodes exclusively from an external node discovery service

TOKEN_AWARE

public static final NodeDiscoveryType TOKEN_AWARE

NONE

public static final NodeDiscoveryType NONE

Use only nodes in the list of seeds

Method Detail

values

public static NodeDiscoveryType[] 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 (NodeDiscoveryType c : NodeDiscoveryType.values())
    System.out.println(c);

Returns:

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

valueOf

public static NodeDiscoveryType valueOf(java.lang.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.
