Method Detail

encodeChanges

public static byte[] encodeChanges(PK pk,
                                   int types)

Encodes several changes of one PK into a byte array.

Returns:

a byte array and its length is 9. The first eight bytes store the long value of PK, and the last one contains the type information.

See Also:

decodeChangeTypes(byte[]), decodePK(byte[])

decodePK

public static PK decodePK(byte[] encodedChanges)

Decoded PK from encoded changes byte array.

Returns:

the decoded PK from the byte array.

See Also:

encodeChanges(PK, int)

decodeChangeTypes

public static int decodeChangeTypes(byte[] encodedChanges)

Decoded changes from encoded changes byte array.

Returns:

the type change information

See Also:

encodeChanges(PK, int)

createEventsFromChanges

public static java.util.Collection<AfterSaveEvent> createEventsFromChanges(byte[][] changes)

Creates the effective set of AfterSaveEvent objects from a array of encoded changes ( which are byte arrays as well). Please note that unnecessary change types are silently removed.

Returns:

all AfterSaveEvents

createEventsFromChanges

public static java.util.Collection<AfterSaveEvent> createEventsFromChanges(byte[][] changes,
                                                                           boolean removeUnnecessaryTypes)

Creates the effective set of AfterSaveEvent objects from a array of encoded changes ( which are byte arrays as well).

Parameters:

removeUnnecessaryTypes - if true change types that are considered unnecessary are not translated into events. These are: any UPDATE which has a matching REMOVE; any UPDATE that has a matching CREATE and no REMOVE.

Returns:

all AfterSaveEvents
