Method Details

loadGlobal

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

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

Specified by:

loadGlobal in interface IndexFieldData.Global<LeafOrdinalsFieldData>

loadGlobalDirect

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

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

Specified by:

loadGlobalDirect in interface IndexFieldData.Global<LeafOrdinalsFieldData>

Throws:

java.lang.Exception

getOrdinalMap

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

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

supportsGlobalOrdinalsMapping

boolean supportsGlobalOrdinalsMapping()

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 getOrdinalMap() will result in an UnsupportedOperationException.
