    • globalInfo

      public abstract String globalInfo()
      Returns a string describing the stemmer
      返回:
      a description suitable for displaying in the explorer/experimenter gui
    • listOptions

      public Enumeration listOptions()
      Returns an enumeration of all the available options..
      指定者:
      listOptions 在接口中 OptionHandler
      返回:
      an enumeration of all available options.
    • getOptions

      public String[] getOptions()
      Gets the current option settings for the OptionHandler.
      指定者:
      getOptions 在接口中 OptionHandler
      返回:
      the list of current option settings as an array of strings
    • setOptions

      public void setOptions(String[] options) throws Exception
      Sets the OptionHandler's options using the given list. All options will be set (or reset) during this call (i.e. incremental setting of options is not possible).
      指定者:
      setOptions 在接口中 OptionHandler
      参数:
      options - the list of options as an array of strings
      抛出:
      Exception - if an option is not supported
    • hasMoreElements

      public abstract boolean hasMoreElements()
      Tests if this enumeration contains more elements.
      指定者:
      hasMoreElements 在接口中 Enumeration
      返回:
      true if and only if this enumeration object contains at least one more element to provide; false otherwise.
    • nextElement

      public abstract Object nextElement()
      Returns the next element of this enumeration if this enumeration object has at least one more element to provide.
      指定者:
      nextElement 在接口中 Enumeration
      返回:
      the next element of this enumeration.
    • tokenize

      public abstract void tokenize(String s)
      Sets the string to tokenize. Tokenization happens immediately.
      参数:
      s - the string to tokenize
    • tokenize

      public static String[] tokenize(Tokenizer tokenizer, String[] options) throws Exception
      initializes the given tokenizer with the given options and runs the tokenizer over all the remaining strings in the options array. If no strings remained in the option string then data is read from stdin, line by line.
      参数:
      tokenizer - the tokenizer to use
      options - the options for the tokenizer
      返回:
      the tokenized strings
      抛出:
      Exception - if setting of options or tokenization fails
    • runTokenizer

      public static void runTokenizer(Tokenizer tokenizer, String[] options)
      initializes the given tokenizer with the given options and runs the tokenizer over all the remaining strings in the options array. The generated tokens are then printed to stdout. If no strings remained in the option string then data is read from stdin, line by line.
      参数:
      tokenizer - the tokenizer to use
      options - the options for the tokenizer
