英文文档：

CHAR

public static final DiscriminatorType CHAR

Single character as the discriminator type

英文文档：

INTEGER

public static final DiscriminatorType INTEGER

Integer as the discriminator type

Method Detail

final public static DiscriminatorType[] values()

英文文档：
values

public static final DiscriminatorType[] values()

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

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

Returns:: an array containing the constants of this enum type, in the order they're declared

public static DiscriminatorType valueOf(String name)

英文文档：
valueOf

public static DiscriminatorType 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
