SINGLE_TABLE

public static final InheritanceType SINGLE_TABLE
A single table per class hierarchy


TABLE_PER_CLASS

public static final InheritanceType TABLE_PER_CLASS
A table per concrete entity class


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

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

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
