Enum Constant Summary
`JOINED` A strategy in which fields that are specific to a subclass are mapped to a separate table than the fields that are common to the parent class, and a join is performed to instantiate the subclass.
`SINGLE_TABLE` A single table per class hierarchy
`TABLE_PER_CLASS` A table per concrete entity class

Method Summary
`static InheritanceType`	`valueOf(String name)` Returns the enum constant of this type with the specified name.
`static InheritanceType[]`	`values()` Returns an array containing the constants of this enum type, in the order they're declared.

Methods inherited from class java.lang.Enum
`clone, compareTo, equals, getDeclaringClass, hashCode, name, ordinal, toString, valueOf`

JOINED

public static final InheritanceType JOINED

A strategy in which fields that are specific to a subclass are mapped to a separate table than the fields that are common to the parent class, and a join is performed to instantiate the subclass.

Method Detail

final public static InheritanceType[] values()

英文文档：
values

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

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

public static InheritanceType valueOf(String name)

英文文档：
valueOf

public static InheritanceType 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
