java.lang.Object
java.lang.Record
org.apache.lucene.util.hnsw.IncrementalHnswGraphMerger.GraphReader
Record Components:
reader - the vectors reader that provides the graph
initDocMap - maps the reader's doc IDs to doc IDs in the merged segment
graphSize - total number of nodes in the graph, including deleted ones
liveVectorCount - number of nodes in the graph whose documents are live
Enclosing class:
IncrementalHnswGraphMerger
protected static record IncrementalHnswGraphMerger.GraphReader(KnnVectorsReader reader, MergeState.DocMap initDocMap, int graphSize, int liveVectorCount) extends Record
Represents a vector reader that contains graph info.

  • Constructor Details

    • GraphReader

      protected GraphReader(KnnVectorsReader reader, MergeState.DocMap initDocMap, int graphSize, int liveVectorCount)
      Creates an instance of a GraphReader record class.
      Parameters:
      reader - the value for the reader record component
      initDocMap - the value for the initDocMap record component
      graphSize - the value for the graphSize record component
      liveVectorCount - the value for the liveVectorCount record component

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with '=='.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • reader

      public KnnVectorsReader reader()
      Returns the value of the reader record component.
      Returns:
      the value of the reader record component

    • initDocMap

      public MergeState.DocMap initDocMap()
      Returns the value of the initDocMap record component.
      Returns:
      the value of the initDocMap record component

    • graphSize

      public int graphSize()
      Returns the value of the graphSize record component.
      Returns:
      the value of the graphSize record component

    • liveVectorCount

      public int liveVectorCount()
      Returns the value of the liveVectorCount record component.
      Returns:
      the value of the liveVectorCount record component
