Class MultiBits

  • All Implemented Interfaces:
    Bits

    public final class MultiBits
    extends Object
    implements Bits
    Concatenates multiple Bits together, on every lookup.

    NOTE: This is very costly, as every lookup must do a binary search to locate the right sub-reader.

    WARNING: This API is experimental and might change in incompatible ways in the next release.
    • Method Detail

      • getLiveDocs

        public static Bits getLiveDocs​(IndexReader reader)
        Returns a single Bits instance for this reader, merging live Documents on the fly. This method will return null if the reader has no deletions.

        NOTE: this is a very slow way to access live docs. For example, each Bits access will require a binary search. It's better to get the sub-readers and iterate through them yourself.

      • get

        public boolean get​(int doc)
        Description copied from interface: Bits
        Returns the value of the bit with the specified index.
        Specified by:
        get in interface Bits
        Parameters:
        doc - index, should be non-negative and < Bits.length(). The result of passing negative or out of bounds values is undefined by this interface, just don't do it!
        Returns:
        true if the bit is set, false otherwise.
      • length

        public int length()
        Description copied from interface: Bits
        Returns the number of bits in this set
        Specified by:
        length in interface Bits
