- - ### Constructor Detail

    - #### TypeTokenFilter

          public TypeTokenFilter​(TokenStream input,
                                 Set<String> stopTypes,
                                 boolean useWhiteList)

      Create a new `TypeTokenFilter`.
      Parameters:
        `input` - the `TokenStream` to consume
        `stopTypes` - the types to filter
        `useWhiteList` - if true, then tokens whose type is in stopTypes will be kept, otherwise they will be filtered out

    - #### TypeTokenFilter

          public TypeTokenFilter​(TokenStream input,
                                 Set<String> stopTypes)

      Create a new `TypeTokenFilter` that filters tokens out (useWhiteList=false).

  - ### Method Detail

    - #### accept

          protected boolean accept()

      By default accept the token if its type is not a stop type. When the useWhiteList parameter is set to true then accept the token if its type is contained in the stopTypes
      Specified by:
        `accept` in class `FilteringTokenFilter`
