JdbcIndexDefinition

JdbcIndexDefinition(DataSource ds,
                    Element element,
                    Set allIndexedFields,
                    boolean storeText,
                    boolean mergeText,
                    org.apache.lucene.analysis.Analyzer a,
                    boolean isSub)

Method Detail

setId

public void setId(String i)

Specified by:

setId in interface IndexDefinition

getId

public String getId()

Specified by:

getId in interface IndexDefinition

getDirectConnection

protected Connection getDirectConnection()
                                  throws SQLException

Jdbc connection pooling of MMBase would kill the statement if too duratious. This produces a 'direct connection' in that case, to circumvent that problem (Indexing queries _may_ take a while).

Throws:

SQLException

getAnalyzer

public org.apache.lucene.analysis.Analyzer getAnalyzer()

Description copied from interface: IndexDefinition

Per index a an Analyzer can be defined.

Specified by:

getAnalyzer in interface IndexDefinition

getFindSql

protected String getFindSql(String identifier)

inIndex

public boolean inIndex(String identifier)

Description copied from interface: IndexDefinition

Whether the object with given key would be included in this index

Specified by:

inIndex in interface IndexDefinition

getSql

protected String getSql(String identifier)

getSqlCursor

CloseableIterator<JdbcIndexDefinition.JdbcEntry> getSqlCursor(String sql)

getNode

public Node getNode(Cloud userCloud,
                    org.apache.lucene.document.Document doc)

Description copied from interface: IndexDefinition

Defines how a Node for this index must be produced. For MMBase indices this is of course quite straight-forward, but other indices may create virtual nodes here.

Specified by:

getNode in interface IndexDefinition

getCursor

public CloseableIterator<JdbcIndexDefinition.JdbcEntry> getCursor()

Description copied from interface: IndexDefinition

Returns an Iterator over all IndexEntry's defined by this index. Only makes sense if this is not a 'sub definition'.

Specified by:

getCursor in interface IndexDefinition

getSubCursor

public CloseableIterator<JdbcIndexDefinition.JdbcEntry> getSubCursor(String identifier)

Description copied from interface: IndexDefinition

Returns an Iterator over all IndexEntry's defined by this index, restricted by a certain identifier. For a 'top' level index definition, this should normally return only one Entry, and the key must be the identifier of this entry. For 'nested' IndexDefinitions, the key most be the key of the parent.

Specified by:

getSubCursor in interface IndexDefinition

toString

public String toString()

Overrides:

toString in class Object
