Enum Constant Detail

NONE

public static final ReactiveListResultsConsumer.UniqueSemantic NONE

Apply no in-memory de-duplication

FILTER

public static final ReactiveListResultsConsumer.UniqueSemantic FILTER

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

ASSERT

public static final ReactiveListResultsConsumer.UniqueSemantic ASSERT

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

NEVER

public static final ReactiveListResultsConsumer.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 ReactiveListResultsConsumer.UniqueSemantic ALLOW

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

Method Detail

values

public static ReactiveListResultsConsumer.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 (ReactiveListResultsConsumer.UniqueSemantic c : ReactiveListResultsConsumer.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 ReactiveListResultsConsumer.UniqueSemantic valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
