Enum EnumDBMasterSlave

java.lang.Object

java.lang.Enum<EnumDBMasterSlave>

org.pinus4j.api.enums.EnumDBMasterSlave

All Implemented Interfaces:

Serializable, Comparable<EnumDBMasterSlave>

public enum EnumDBMasterSlave
extends Enum<EnumDBMasterSlave>

数据库主从选择枚举. 每一个数据库集群可以有若干个从库，从库和主库的数据是实时同步的. 目前先支持4个从库，如果有更多的从库可以添加此枚举的值即可.

Method Detail

values

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

Returns:

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

valueOf

public static EnumDBMasterSlave 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

getValue
