Method Detail

convertSpringToSpaceIsolationLevel

public static int convertSpringToSpaceIsolationLevel(int springIsolationLevel,
                                                     int defaultValue)

Parameters:

springIsolationLevel - the spring isolation level as defined in TransactionDefinition.

defaultValue - The modifiers to use in case springIsolationLevel equals TransactionDefinition.ISOLATION_DEFAULT

Returns:

A matcing GigaSpaces isolation level modifier.

toReadModifiers

public static ReadModifiers toReadModifiers(int isolationLevel)

Parameters:

isolationLevel - The isolation level code number.

Returns:

a ReadModifiers instance representing the isolationLevel parameter

toCountModifiers

public static CountModifiers toCountModifiers(int isolationLevel)

Parameters:

isolationLevel - The isolation level code number.

Returns:

a CountModifiers instance representing the isolationLevel parameter

mergeWithIsolationLevelModifiersIfNeeded

public static ReadModifiers mergeWithIsolationLevelModifiersIfNeeded(ReadModifiers modifiers,
                                                                     GigaSpace gigaSpace)

Parameters:

modifiers - The modifiers to merge the isolation level with.

gigaSpace - The GigaSpace instance to test the current isolation level with.

Returns:

The merged modifiers (i.e, if there is a current transaction defined and it has a non default isolation level set, it will replace any currently set isolation level on the modifiers argument.

mergeWithIsolationLevelModifiersIfNeeded

public static CountModifiers mergeWithIsolationLevelModifiersIfNeeded(CountModifiers modifiers,
                                                                      GigaSpace gigaSpace)

Parameters:

modifiers - The modifiers to merge the isolation level with.

gigaSpace - The GigaSpace instance to test the current isolation level with.

Returns:

The merged modifiers (i.e, if there is a current transaction defined and it has a non default isolation level set, it will replace any currently set isolation level on the modifiers argument.
