Enum Constant Detail

NONE

public static final StandardOptimizerDescriptor NONE

Describes the optimizer for no optimization

HILO

public static final StandardOptimizerDescriptor HILO

Describes the optimizer for using a custom "hilo" algorithm optimization

LEGACY_HILO

public static final StandardOptimizerDescriptor LEGACY_HILO

Describes the optimizer for using a custom "hilo" algorithm optimization, following the legacy Hibernate hilo algorithm

POOLED

public static final StandardOptimizerDescriptor POOLED

Describes the optimizer for use with tables/sequences that store the chunk information. Here, specifically the hi value is stored in the database.

POOLED_LO

public static final StandardOptimizerDescriptor POOLED_LO

Describes the optimizer for use with tables/sequences that store the chunk information. Here, specifically the lo value is stored in the database.

POOLED_LOTL

public static final StandardOptimizerDescriptor POOLED_LOTL

Describes the optimizer for use with tables/sequences that store the chunk information. Here, specifically the lo value is stored in the database and ThreadLocal used to cache the generation state.

Method Detail

values

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

Returns:

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

valueOf

public static StandardOptimizerDescriptor 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

getExternalName

public String getExternalName()

getOptimizerClass

public Class<? extends Optimizer> getOptimizerClass()

isPooled

public boolean isPooled()

fromExternalName

public static StandardOptimizerDescriptor fromExternalName(String externalName)

Interpret the incoming external name into the appropriate enum value

Parameters:

externalName - The external name

Returns:

The corresponding enum value; if no external name is supplied, NONE is returned; if an unrecognized external name is supplied, null is returned
