Method Detail

values

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

Returns:

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

valueOf

public static RingMemberHostMapper 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

mapHosts

public Collection<RingMember> mapHosts(Iterable<com.datastax.driver.core.Host> hosts)
                                throws com.datastax.driver.core.exceptions.DriverException

Description copied from interface: HostMapper

Implementations must implement this method to map each Host in the Metadata.

Specified by:

mapHosts in interface HostMapper<RingMember>

Parameters:

hosts - the Iterable of Hosts to map, must not be null.

Returns:

the result objects for the given hosts.

Throws:

com.datastax.driver.core.exceptions.DriverException - if a DriverException is encountered mapping values (that is, there's no need to catch DriverException).
