  - ### Constructor Detail

    - #### AbstractAutocomplete

          public AbstractAutocomplete()

  - ### Method Detail

    - #### getFetchValue

          public abstract Object getFetchValue()

      A value to set in the target input element on a choice suggestion that isn't shown in the suggestion table. It can be used for descriptive output comments or suggestions. If not set, all text in the suggestion row is set as a value

    - #### getSelectedItemClass

          public abstract String getSelectedItemClass()

      Assigns one or more space-separated CSS class names to the selected suggestion entry

    - #### getPopupClass

          public abstract String getPopupClass()

      Assigns one or more space-separated CSS class names to the content of the popup suggestion element

    - #### getInputClass

          public abstract String getInputClass()

      Assigns one or more space-separated CSS class names to the input element

    - #### getLayout

          public abstract String getLayout()

      Type of the layout encoded using nested components should be defined using layout attribute. Possible values are:

      list
        suggestions wrapped to HTML unordered list
      div
        suggestions wrapped with just div element
      table
        suggestions are encoded as table rows, column definitions are required in this case

      Default: div

    - #### getTokens

          public abstract String getTokens()

      Allow a user to enter multiple values separated by specific characters. As the user types, a suggestion will present as normal. When they enter the specified token character, this begins a new suggestion process, and the component will then only use text entered after the token character for suggestions.

      Make sure that no character defined in tokens is part of any suggestion value. E.g. do not use space as a token if you expect to allow spaces in suggestion values.

      When tokens defined, they can be naturally separated by space character - input separated by tokens ', ' or ' ,' will be considered as it would be ',' token without any space.

      Default: true

    - #### getClientFilterFunction

          public abstract String getClientFilterFunction()

      A javascript function used to filter the result list returned from the ajax call to the server. This function should have two parameters; subString(current input value considering tokens) and value (currently iterated item value) and return boolean flag which means if the value satisfies the substring passed. The function will be called for every available suggestion in order to construct a new list of suggestions.

      Default: A javascript method called startsWith
