Constructor Detail

OLuceneSpatialIndex

public OLuceneSpatialIndex(String name,
                           String typeId,
                           String algorithm,
                           int version,

                           int binaryFormatVersion)

Method Detail

put

public OLuceneIndexNotUnique put(Object key,
                                 OIdentifiable singleValue)

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<Set<OIdentifiable>>

Overrides:

put in class OLuceneIndexNotUnique

Parameters:

key - Entry's key

singleValue - 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<Set<OIdentifiable>>

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

interpretAsSpatial

protected Iterable<OTransactionIndexChangesPerKey.OTransactionIndexEntry> interpretAsSpatial(List<OTransactionIndexChangesPerKey.OTransactionIndexEntry> entries)
