Enum Constant Detail

英文文档：

ORDINAL

public static final EnumType ORDINAL

Persist enumerated type property or field as an integer

英文文档：

STRING

public static final EnumType STRING

Persist enumerated type property or field as a string

Method Detail

final public static EnumType[] values()

英文文档：
values

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

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

public static EnumType valueOf(String name)

英文文档：
valueOf

public static EnumType 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
