## Class EclipseLinkJpaVendorAdapter

- java.lang.Object
- - org.springframework.orm.jpa.vendor.AbstractJpaVendorAdapter
  - - org.springframework.orm.jpa.vendor.EclipseLinkJpaVendorAdapter

- All Implemented Interfaces:
    JpaVendorAdapter

      public class EclipseLinkJpaVendorAdapter
      extends AbstractJpaVendorAdapter

  `JpaVendorAdapter` implementation for Eclipse Persistence Services (EclipseLink). Developed and tested against EclipseLink 1.0 as well as 2.0-2.3.

  Exposes EclipseLink's persistence provider and EntityManager extension interface, and supports `AbstractJpaVendorAdapter`'s common configuration settings.

  This class is very analogous to `TopLinkJpaVendorAdapter`, since EclipseLink is effectively the next generation of the TopLink product. Thanks to Mike Keith for the original EclipseLink support prototype!

  NOTE: No need to filter out classes from the JPA providers package for EclipseLink (see SPR-6040)

  - ### Method Detail

    - #### getPersistenceProvider

          public PersistenceProvider getPersistenceProvider()

      Description copied from interface: `JpaVendorAdapter`
      Return the vendor-specific persistence provider.

    - #### getJpaPropertyMap

          public Map<String,Object> getJpaPropertyMap()

      Description copied from interface: `JpaVendorAdapter`
      Return a Map of vendor-specific JPA properties, typically based on settings in this JpaVendorAdapter instance.

      Note that there might be further JPA properties defined on the EntityManagerFactory bean, which might potentially override individual JPA property values specified here.

      Specified by:
        `getJpaPropertyMap` in interface `JpaVendorAdapter`
      Overrides:
        `getJpaPropertyMap` in class `AbstractJpaVendorAdapter`
      Returns:
        a Map of JPA properties, as as accepted by the standard JPA bootstrap facilities, or `null` or an empty Map if there are no such properties to expose
      See Also:
        `Persistence.createEntityManagerFactory(String, java.util.Map)`, `PersistenceProvider.createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo, java.util.Map)`

    - #### determineTargetDatabaseName

          protected String determineTargetDatabaseName(Database database)

      Determine the EclipseLink target database name for the given database.
      Parameters:
        `database` - the specified database
      Returns:
        the EclipseLink target database name, or `null` if none found

    - #### getJpaDialect

          public JpaDialect getJpaDialect()

      Description copied from interface: `JpaVendorAdapter`
      Return the vendor-specific JpaDialect implementation for this provider, or `null` if there is none.
      Specified by:
        `getJpaDialect` in interface `JpaVendorAdapter`
      Overrides:
        `getJpaDialect` in class `AbstractJpaVendorAdapter`

    - #### getEntityManagerInterface

          public Class<? extends EntityManager> getEntityManagerInterface()

      Description copied from interface: `JpaVendorAdapter`
      Return the vendor-specific EntityManager interface that this provider's EntityManagers will implement.

      If the provider does not offer any EntityManager extensions, the adapter should simply return the standard `EntityManager` class here.

      Specified by:
        `getEntityManagerInterface` in interface `JpaVendorAdapter`
      Overrides:
        `getEntityManagerInterface` in class `AbstractJpaVendorAdapter`
