public IndexCollection()

Method Details

add

public boolean add(Index<T> index)

Specified by:

add in interface Collection<T>

Overrides:

add in class AbstractCollection<Index<T>>

getRows

public void getRows(Map<String,Constraint> constraints,
 IndexMetaNode node,
 List<Integer> path)

get

public Collection<List<Object>> get(Map<String,Constraint> constraints,
 IndexMap<String,Column> columns)

Parameters:

columnNames -

Returns:

execute

public Collection<List<Object>> execute(Index index,
 org.aksw.sparqlify.database.IndexCandidate pathNode,
 org.aksw.sparqlify.database.RowRechecker rechecker)

_execute

public void _execute(Object store,
 org.aksw.sparqlify.database.IndexCandidate pathNode,
 Collection<List<Object>> result,
 org.aksw.sparqlify.database.RowRechecker rechecker)

get

public org.aksw.sparqlify.database.IndexCandidate get(List<IndexMetaNode> nodes,
 int baseNodeDepth,
 int baseColumnDepth,
 Map<String,Constraint> constraints)

TODO Given {a = const , b = const} and an index (a, b) with support for equals. How can we pass on the constraints??? For now lets assume only single column indexes... :/

Parameters:

nodes -

baseNodeDepth -

baseColumnDepth -

constraints -

Returns:

iterator
