Field Detail

• SHORT_CIRCUIT_INDICATOR

  public static final Serializable SHORT_CIRCUIT_INDICATOR

  Marker object returned from IdentifierGenerator.generate(org.hibernate.engine.SessionImplementor, java.lang.Object) to indicate that we should short-circuit any continued generated id checking. Currently this is only used in the case of the foreign generator as a way to signal that we should use the associated entity's id value.

• POST_INSERT_INDICATOR

  public static final Serializable POST_INSERT_INDICATOR

  Marker object returned from IdentifierGenerator.generate(org.hibernate.engine.SessionImplementor, java.lang.Object) to indicate that the entity's identifier will be generated as part of the datbase insertion.

  type - The expected type mapping for the identity value.

  Returns:

  The generated identity value

  Throws:

                                 IdentifierGenerationException

  Extract the value from the result set (which is assumed to already have been positioned to the apopriate row) and wrp it in the appropriate Java numeric type.

  Parameters:

  rs - The result set from which to extract the value.

  identifierColumnName - The name of the identifier column

  type - The expected type of the value.

  Returns:

  The extracted value.

  Throws:

  SQLException - Indicates problems access the result set
