Enum Constant Detail

SEQUENTIAL

public static final HaMode SEQUENTIAL

sequential: driver will always connect according to connection string order

LOADBALANCE

public static final HaMode LOADBALANCE

load-balance: driver will randomly connect to any host, permitting balancing connections

NONE

public static final HaMode NONE

no ha-mode. Connect to first host only

Method Detail

values

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

Returns:

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

valueOf

public static HaMode 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

from

public static HaMode from(String value)

Get HAMode from values or aliases

Parameters:

value - value or alias

Returns:

HaMode if corresponding mode is found
