Method Details

getOrdinalMap

public org.apache.lucene.index.OrdinalMap getOrdinalMap()

Description copied from interface: IndexOrdinalsFieldData

Returns the underlying OrdinalMap for this fielddata or null if global ordinals are not needed (constant value or single segment).

Specified by:

getOrdinalMap in interface IndexOrdinalsFieldData

loadGlobal

public IndexOrdinalsFieldData loadGlobal(org.apache.lucene.index.DirectoryReader indexReader)

Description copied from interface: IndexOrdinalsFieldData

Load a global view of the ordinals for the given IndexReader, potentially from a cache.

Specified by:

loadGlobal in interface IndexFieldData.Global<LeafOrdinalsFieldData>

Specified by:

loadGlobal in interface IndexOrdinalsFieldData

localGlobalDirect

public IndexOrdinalsFieldData localGlobalDirect(org.apache.lucene.index.DirectoryReader indexReader) throws java.lang.Exception

Description copied from interface: IndexOrdinalsFieldData

Load a global view of the ordinals for the given IndexReader.

Specified by:

localGlobalDirect in interface IndexFieldData.Global<LeafOrdinalsFieldData>

Specified by:

localGlobalDirect in interface IndexOrdinalsFieldData

Throws:

java.lang.Exception

empty

protected LeafOrdinalsFieldData empty(int maxDoc)

Specified by:

empty in class AbstractIndexFieldData<LeafOrdinalsFieldData>

Parameters:

maxDoc - of the current reader

Returns:

an empty field data instances for field data lookups of empty segments (returning no values)

filter

protected org.apache.lucene.index.TermsEnum filter(org.apache.lucene.index.Terms terms, org.apache.lucene.index.TermsEnum iterator, org.apache.lucene.index.LeafReader reader) throws java.io.IOException

Throws:

java.io.IOException

supportsGlobalOrdinalsMapping

public boolean supportsGlobalOrdinalsMapping()

Description copied from interface: IndexOrdinalsFieldData

Whether this field data is able to provide a mapping between global and segment ordinals, by returning the underlying OrdinalMap. If this method returns false, then calling IndexOrdinalsFieldData.getOrdinalMap() will result in an UnsupportedOperationException.

Specified by:

supportsGlobalOrdinalsMapping in interface IndexOrdinalsFieldData
