Record Class ValuesSourceReaderOperator.FieldInfo

java.lang.Object
java.lang.Record
org.elasticsearch.compute.lucene.read.ValuesSourceReaderOperator.FieldInfo
Record Components:
nullsFiltered - if true, then target docs passed from the source operator are guaranteed to have a value for the field; otherwise, the guarantee is unknown. This enables optimizations for block loaders, treating the field as dense (every document has value) even if it is sparse in the index. For example, "FROM index | WHERE x != null | STATS sum(x)", after filtering out documents without value for field x, all target documents returned from the source operator will have a value for field x whether x is dense or sparse in the index.
blockLoader - maps shard index to the BlockLoaders which load the actual blocks.
Enclosing class:

      Creates an instance of a FieldInfo record class.
      Parameters:
      name - the value for the name 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.
    • name

      public String name()
      Returns the value of the name record component.
      Returns:
      the value of the name record component
    • type

      public ElementType type()
      Returns the value of the type record component.
      Returns:
      the value of the type record component
    • nullsFiltered

      public boolean nullsFiltered()
      Returns the value of the nullsFiltered record component.
      Returns:
      the value of the nullsFiltered record component
    • blockLoader

      public IntFunction<BlockLoader> blockLoader()
      Returns the value of the blockLoader record component.
      Returns:
      the value of the blockLoader record component
