getFieldInfos
public FieldInfos getFieldInfos()
Description copied from class:LeafReader
Get theFieldInfos
describing all fields in this reader.Note: Implementations should cache the FieldInfos instance returned by this method such that subsequent calls to this method return the same instance.
- Overrides:
getFieldInfos
in classFilterLeafReader

Description copied from class:LeafReader
ReturnsNumericDocValues
for this field, or null if no numeric doc values were indexed for this field. The returned instance should only be used by a single thread.- Overrides:

getCoreCacheHelper
public IndexReader.CacheHelper getCoreCacheHelper()
Description copied from class:LeafReader
Optional method: Return aIndexReader.CacheHelper
that can be used to cache based on the content of this leaf regardless of deletions. Two readers that have the same data but different sets of deleted documents or doc values updates may be considered equal. Consider usingIndexReader.getReaderCacheHelper()
if you need deletions or dv updates to be taken into account.A return value of
null
indicates that this reader is not suited for caching, which is typically the case for short-lived wrappers that alter the content of the wrapped leaf reader.- Specified by:
getCoreCacheHelper
in classLeafReader
