  - ### Method Detail

    - #### getReusableComponents

          public abstract Analyzer.TokenStreamComponents getReusableComponents(Analyzer analyzer,
                                                                               String fieldName)

      Gets the reusable TokenStreamComponents for the field with the given name.
      Parameters:
        `analyzer` - Analyzer from which to get the reused components. Use `getStoredValue(Analyzer)` and `setStoredValue(Analyzer, Object)` to access the data on the Analyzer.
        `fieldName` - Name of the field whose reusable TokenStreamComponents are to be retrieved
      Returns:
        Reusable TokenStreamComponents for the field, or `null` if there was no previous components for the field

    - #### setReusableComponents

          public abstract void setReusableComponents(Analyzer analyzer,
                                                     String fieldName,
                                                     Analyzer.TokenStreamComponents components)

      Stores the given TokenStreamComponents as the reusable components for the field with the give name.
      Parameters:
        `fieldName` - Name of the field whose TokenStreamComponents are being set
        `components` - TokenStreamComponents which are to be reused for the field

    - #### getStoredValue

          protected final Object getStoredValue(Analyzer analyzer)

      Returns the currently stored value.
      Returns:
        Currently stored value or `null` if no value is stored
      Throws:
        `AlreadyClosedException` - if the Analyzer is closed.

    - #### setStoredValue

          protected final void setStoredValue(Analyzer analyzer,
                                              Object storedValue)

      Sets the stored value.
      Parameters:
        `storedValue` - Value to store
      Throws:
        `AlreadyClosedException` - if the Analyzer is closed.
