## [Java] Enum JsonTokenType

- groovy.json.JsonTokenType

-     public enum JsonTokenType

  The original slurper and lexer use this class. This is kept around in case someone needs its exact behavior. Enum listing all the possible JSON tokens that should be recognized by the lexer.

  Since:
    1.8.0

    - #### public JsonTokenType CLOSE_BRACKET

    - #### public JsonTokenType CLOSE_CURLY

    - #### public JsonTokenType COLON

    - #### public JsonTokenType COMMA

    - #### public JsonTokenType FALSE

    - #### public JsonTokenType NULL

    - #### public JsonTokenType NUMBER

    - #### public JsonTokenType OPEN_BRACKET

    - #### public JsonTokenType OPEN_CURLY

    - #### public JsonTokenType STRING

      Original pattern throws the StackOverflowError for long strings with backslashes. So it is replaced by a 2-step approach inspired from json2.js sources: https://github.com/douglascrockford/JSON-js/blob/master/json2.js#L462 See JsonTokenTypeTest#testMatchingLongStringWithBackslashes() for details.

    - #### public JsonTokenType TRUE

  - ### Method Detail

    - #### public boolean doCall(String it)

    - #### public String getLabel()

    - #### public Object getValidator()

    - #### public boolean matching(String input)

      Tells if an input string matches a token.

      Parameters:
        `input` - the input string to match
      Returns:
        a `Matching` enum value: `YES` if this is an exact match, `POSSIBLE` if more characters could turn the input string into a valid token, or `NO` if the string cannot possibly match the pattern even with more characters to read.

    - #### public static JsonTokenType startingWith(char c)

      Find which JSON value might be starting with a given character

      Parameters:
        `c` - the character
      Returns:
        the possible token type found
