  • Method Details

    • numDocs

      public int numDocs()
      Description copied from class: IndexReader
      Returns the number of documents in this index.

      NOTE: This operation may run in O(maxDoc). Implementations that can't return this number in constant-time should cache it.

      Overrides:
      numDocs in class FilterCodecReader
    • getLiveDocs

      public Bits getLiveDocs()
      Description copied from class: LeafReader
      Returns the Bits representing live (not deleted) docs. A set bit indicates the doc ID has not been deleted. If this method returns null it means there are no deleted documents (all documents are live).

      The returned instance has been safely published for use by multiple threads without additional synchronization.

      Overrides:
      getLiveDocs in class FilterCodecReader
    • getCoreCacheHelper

      public IndexReader.CacheHelper getCoreCacheHelper()
      Description copied from class: LeafReader
      Optional method: Return a IndexReader.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 using IndexReader.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.

      Description copied from class: IndexReader
