Enum Constant Detail

• FETCH

  public static final GraphSemantic FETCH

  Indicates that anEntityGraph should be interpreted as a JPA "fetch graph".

  • Attributes explicitly specified using anAttributeNodes are treated asFetchType.EAGER and fetched via a join or subsequent select.
  • Attributes not explicitly specified are treated asFetchType.LAZY and are not fetched.

• LOAD

  public static final GraphSemantic LOAD

  Indicates that anEntityGraph should be interpreted as a JPA "load graph".

  • Attributes explicitly specified using anAttributeNodes are treated asFetchType.EAGER and fetched via a join or subsequent select.
  • Attributes not explicitly specified are treated asFetchType.LAZY orFetchType.EAGER depending on the mapping of the attribute, instead of forcingFetchType.LAZY.

Method Detail

• values

  public static GraphSemantic[] values()

  Returns an array containing the constants of this enum type, inthe order they are declared. This method may be used to iterateover the constants as follows:

  for (GraphSemantic c : GraphSemantic.values())    System.out.println(c);

  Returns:

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

• valueOf

  public static GraphSemantic valueOf​(String name)

  Returns the enum constant of this type with the specified name.The string must matchexactly an identifier used to declare anenum 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

• getJakartaHintName

  public String getJakartaHintName()

  The corresponding Jakarta Persistence hint name.

• getJpaHintName

  @Deprecated(since="6.0")public String getJpaHintName()

  Deprecated.

  UsegetJakartaHintName() instead
  The hint name that should be used with Java Persistence.

• fromHintName

  public static GraphSemantic fromHintName​(String hintName)

• fromJpaHintName

  @Deprecated(since="6.0")public static GraphSemantic fromJpaHintName​(String hintName)

  Deprecated.

  UsefromHintName(java.lang.String) instead
