Constructor Detail

OLuceneSpatialIndex

public OLuceneSpatialIndex(String name,
                           String typeId,
                           String algorithm,
                           int version,
                           OAbstractPaginatedStorage storage,
                           String valueContainerAlgorithm,
                           ODocument metadata,
                           int binaryFormatVersion)

Method Detail

put

public OLuceneIndexNotUnique put(Object key,
                                 OIdentifiable value)

Description copied from interface: OIndex

Inserts a new entry in the index. The behaviour depends by the index implementation.

Specified by:

put in interface OIndex

Overrides:

put in class OLuceneIndexNotUnique

Parameters:

key - Entry's key

value - Entry's value as OIdentifiable instance

Returns:

The index instance itself to allow in chain calls

interpretTxKeyChanges

public Iterable<OTransactionIndexChangesPerKey.OTransactionIndexEntry> interpretTxKeyChanges(OTransactionIndexChangesPerKey changes)

Description copied from class: OIndexAbstract

Interprets transaction index changes for a certain key. Override it to customize index behaviour on interpreting index changes. This may be viewed as an optimization, but in some cases this is a requirement. For example, if you put multiple values under the same key during the transaction for single-valued/unique index, but remove all of them except one before commit, there is no point in throwing ORecordDuplicatedException while applying index changes.

Specified by:

interpretTxKeyChanges in interface OIndexInternal

Overrides:

interpretTxKeyChanges in class OLuceneIndexNotUnique

Parameters:

changes - the changes to interpret.

Returns:

the interpreted index key changes.

encodeKey

protected Object encodeKey(Object key)

Overrides:

encodeKey in class OLuceneIndexNotUnique

decodeKey

protected Object decodeKey(Object key)

Overrides:

decodeKey in class OLuceneIndexNotUnique
