Enum Constant Summary

FETCH
When the javax.persistence.fetchgraph property is used to specify an entity graph, attributes that are specified by attribute nodes of the entity graph are treated as FetchType.EAGER and attributes that are not specified are treated as FetchType.LAZY

LOAD
When the javax.persistence.loadgraph property is used to specify an entity graph, attributes that are specified by attribute nodes of the entity graph are treated as FetchType.EAGER and attributes that are not specified are treated according to their specified or default FetchType.

Method Summary

String	getKey()
static EntityGraph.EntityGraphType	valueOf(String name) Returns the enum constant of this type with the specified name.
static EntityGraph.EntityGraphType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

LOAD

public static final EntityGraph.EntityGraphType LOAD

When the javax.persistence.loadgraph property is used to specify an entity graph, attributes that are specified by attribute nodes of the entity graph are treated as FetchType.EAGER and attributes that are not specified are treated according to their specified or default FetchType.

2.1 Specification: 3.7.4.2 Load Graph Semantics

FETCH

public static final EntityGraph.EntityGraphType FETCH

When the javax.persistence.fetchgraph property is used to specify an entity graph, attributes that are specified by attribute nodes of the entity graph are treated as FetchType.EAGER and attributes that are not specified are treated as FetchType.LAZY

Method Detail

values

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

Returns:

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

valueOf

public static EntityGraph.EntityGraphType 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

getKey

public String getKey()
