- java.lang.Object
- - org.apache.lucene.util.mutable.MutableValue
  - - org.apache.lucene.util.mutable.MutableValueDouble

- All Implemented Interfaces:
    Comparable<MutableValue>

      public class MutableValueDouble
      extends MutableValue

  `MutableValue` implementation of type `double`. When mutating instances of this object, the caller is responsible for ensuring that any instance where `exists` is set to `false` must also `value` set to `0.0D` for proper operation.
