SUMMARY: NESTED | ENUM CONSTANTS | FIELD | METHOD

DETAIL: ENUM CONSTANTS | FIELD | METHOD

org.springframework.orm.jpa.vendor
Enum Database

java.lang.Object
  java.lang.Enum<Database>
      org.springframework.orm.jpa.vendor.Database

All Implemented Interfaces:: Serializable, Comparable<Database>

public enum Database
extends Enum<Database>
extends Enum<Database>

Enumeration for common database platforms. Allows strong typing of database type and portable configuration between JpaVendorDialect implementations.

If a given PersistenceProvider supports a database not listed here, the strategy class can still be specified using the FQN. This is merely a convenience. The database products listed here are the same as those explicitly supported for Spring JDBC exception translation in sql-error-codes.xml.

Method Detail

values

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

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

valueOf

public static Database 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
