Enum Constant Summary

Enum Constants

Enum Constant	Description
ALLOW	De-duplication is allowed if the query and result type allow
ASSERT	Apply in-memory duplication checks, throwing a HibernateException when duplicates are found
FILTER	Apply in-memory de-duplication, removing rows already part of the results
NEVER	Never apply unique handling.
NONE	Apply no in-memory de-duplication

Method Summary

Enum Constant Detail

NONE

public static final ListResultsConsumer.UniqueSemantic NONE

Apply no in-memory de-duplication

FILTER

public static final ListResultsConsumer.UniqueSemantic FILTER

Apply in-memory de-duplication, removing rows already part of the results

ASSERT

public static final ListResultsConsumer.UniqueSemantic ASSERT

Apply in-memory duplication checks, throwing a HibernateException when duplicates are found

NEVER

public static final ListResultsConsumer.UniqueSemantic NEVER

Never apply unique handling. E.g. for NativeQuery. Whereas NONE can be adjusted, NEVER will never apply unique handling

ALLOW

public static final ListResultsConsumer.UniqueSemantic ALLOW

De-duplication is allowed if the query and result type allow

Method Detail

values

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

Returns:

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

valueOf

public static ListResultsConsumer.UniqueSemantic 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
