    - #### FlagsAttributeImpl

          public FlagsAttributeImpl()

      Initialize this attribute with no bits set

  - ### Method Detail

    - #### getFlags

          public int getFlags()

      Description copied from interface: `FlagsAttribute`
      Get the bitset for any bits that have been set.
      Specified by:
        `getFlags` in interface `FlagsAttribute`
      Returns:
        The bits
      See Also:
        `FlagsAttribute.getFlags()`

    - #### setFlags

          public void setFlags​(int flags)

      Description copied from interface: `FlagsAttribute`
      Set the flags to a new bitset.
      Specified by:
        `setFlags` in interface `FlagsAttribute`
      See Also:
        `FlagsAttribute.getFlags()`

    - #### clear

          public void clear()

      Description copied from class: `AttributeImpl`
      Clears the values in this AttributeImpl and resets it to its default value. If this implementation implements more than one Attribute interface it clears all.
      Specified by:
        `clear` in class `AttributeImpl`

    - #### equals

          public boolean equals​(Object other)

      Overrides:
        `equals` in class `Object`

    - #### hashCode

          public int hashCode()

      Overrides:
        `hashCode` in class `Object`

    - #### copyTo

          public void copyTo​(AttributeImpl target)

      Description copied from class: `AttributeImpl`
      Copies the values from this Attribute into the passed-in target attribute. The target implementation must support all the Attributes this implementation supports.
      Specified by:
        `copyTo` in class `AttributeImpl`

    - #### reflectWith

          public void reflectWith​(AttributeReflector reflector)

      Description copied from class: `AttributeImpl`
      This method is for introspection of attributes, it should simply add the key/values this attribute holds to the given `AttributeReflector`.

      Implementations look like this (e.g. for a combined attribute implementation):

             public void reflectWith(AttributeReflector reflector) {
               reflector.reflect(CharTermAttribute.class, "term", term());
               reflector.reflect(PositionIncrementAttribute.class, "positionIncrement", getPositionIncrement());
             }

      If you implement this method, make sure that for each invocation, the same set of `Attribute` interfaces and keys are passed to `AttributeReflector.reflect(java.lang.Class<? extends org.apache.lucene.util.Attribute>, java.lang.String, java.lang.Object)` in the same order, but possibly different values. So don't automatically exclude e.g. `null` properties!

      Specified by:
        `reflectWith` in class `AttributeImpl`

        `AttributeImpl.reflectAsString(boolean)`
