Enum Class GraphSemantic

java.lang.Object

java.lang.Enum<GraphSemantic>

org.hibernate.graph.GraphSemantic

All Implemented Interfaces:

Serializable, Comparable<GraphSemantic>, Constable

public enum GraphSemantic
extends Enum<GraphSemantic>

JPA specifies two distinct ways to apply an EntityGraph - as a "fetch graph" or as a "load graph".

Enum Constant Details

FETCH

public static final GraphSemantic FETCH

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

• Attributes explicitly specified using an AttributeNodes are treated as FetchType.EAGER and fetched via a join or subsequent select.
• Attributes not explicitly specified are treated as FetchType.LAZY and are not fetched.

LOAD

public static final GraphSemantic LOAD

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

• Attributes explicitly specified using an AttributeNodes are treated as FetchType.EAGER and fetched via a join or subsequent select.
• Attributes not explicitly specified are treated as FetchType.LAZY or FetchType.EAGER depending on the mapping of the attribute, instead of forcing FetchType.LAZY.

Method Details

values

public static GraphSemantic[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static GraphSemantic valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class 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.

Use getJakartaHintName() 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.

Use fromHintName(java.lang.String) instead
