DEFAULT

public static final FetchMode DEFAULT

Default to the setting configured in the mapping file.

JOIN

public static final FetchMode JOIN

Fetch using an outer join. Equivalent to fetch="join".

SELECT

public static final FetchMode SELECT

Fetch eagerly, using a separate select. Equivalent to fetch="select".

Field Detail

LAZY

public static final FetchMode LAZY

Deprecated. use FetchMode.SELECT

Fetch lazily. Equivalent to outer-join="false".

EAGER

public static final FetchMode EAGER

Deprecated. use FetchMode.JOIN

Fetch eagerly, using an outer join. Equivalent to outer-join="true".

Method Detail

values

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

Returns:

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

valueOf

public static FetchMode 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
