      public abstract class AbstractJFlexCTokenMaker
      extends AbstractJFlexTokenMaker

  Base class for JFlex-based token makers using C-style syntax. This class knows how to:

  - ### Method Detail

    - #### createInsertBreakAction

          protected Action createInsertBreakAction()

      Creates and returns the action to use when the user inserts a newline. The default implementation intelligently closes multi-line comments. Subclasses can override.
      Returns:
        The action.
      See Also:
        `getInsertBreakAction()`

    - #### getCurlyBracesDenoteCodeBlocks

          public boolean getCurlyBracesDenoteCodeBlocks​(int languageIndex)

      Returns `true` always as C-style languages use curly braces to denote code blocks.
      Specified by:
        `getCurlyBracesDenoteCodeBlocks` in interface `TokenMaker`
      Overrides:
        `getCurlyBracesDenoteCodeBlocks` in class `TokenMakerBase`
      Parameters:
        `languageIndex` - The language index at the offset in question. Since some `TokenMaker`s effectively have nested languages (such as JavaScript in HTML), this parameter tells the `TokenMaker` what sub-language to look at.
      Returns:
        `true` always.

    - #### getInsertBreakAction

          public Action getInsertBreakAction()

      Returns an action to handle "insert break" key presses (i.e. Enter). An action is returned that handles newlines differently in multi-line comments.
      Specified by:
        `getInsertBreakAction` in interface `TokenMaker`
      Overrides:
        `getInsertBreakAction` in class `TokenMakerBase`
      Returns:
        The action.

    - #### getMarkOccurrencesOfTokenType

          public boolean getMarkOccurrencesOfTokenType​(int type)

      Returns whether tokens of the specified type should have "mark occurrences" enabled for the current programming language. The default implementation returns true if `type` is `TokenTypes.IDENTIFIER`. Subclasses can override this method to support other token types, such as `TokenTypes.VARIABLE`.
      Specified by:
        `getMarkOccurrencesOfTokenType` in interface `TokenMaker`
      Overrides:
        `getMarkOccurrencesOfTokenType` in class `TokenMakerBase`
      Parameters:
        `type` - The token type.
      Returns:
        Whether tokens of this type should have "mark occurrences" enabled.

    - #### getShouldIndentNextLineAfter

          public boolean getShouldIndentNextLineAfter​(Token t)

      The default implementation returns `false` always. Languages that wish to better support auto-indentation can override this method.
      Specified by:
        `getShouldIndentNextLineAfter` in interface `TokenMaker`
      Overrides:
        `getShouldIndentNextLineAfter` in class `TokenMakerBase`
      Parameters:
        `t` - The token the previous line ends with.
      Returns:
        Whether the next line should be indented.
