    • TestJSONTokener

      public TestJSONTokener(String s)
      Construct a JSONTokener from a string.
      Parameters:
      s - A source string.

  • Method Details

    • back

      public void back()
      Back up one character. This provides a sort of lookahead capability, so that you can test for a digit or letter before attempting to parse the next number or identifier.

    • dehexchar

      public static int dehexchar(char c)
      Get the hex value of a character (base16).
      Parameters:
      c - A character between '0' and '9' or between 'A' and 'F' or between 'a' and 'f'.
      Returns:
      An int between 0 and 15, or -1 if c was not a hex digit.

    • more

      public boolean more()
      Determine if the source string still contains characters that next() can consume.
      Returns:
      true if not yet at the end of the source.

    • next

      public char next()
      Get the next character in the source string.
      Returns:
      The next character, or 0 if past the end of the source string.

    • next

      public char next(char c) throws TestJSONException
      Consume the next character, and check that it matches a specified character.
      Parameters:
      c - The character to match.
      Returns:
      The character.
      Throws:
      TestJSONException - if the character does not match.

    • next

      public String next(int n) throws TestJSONException
      Get the next n characters.
      Parameters:
      n - The number of characters to take.
      Returns:
      A string of n characters.
      Throws:
      TestJSONException - Substring bounds error if there are not n characters remaining in the source string.

    • nextClean

      public char nextClean() throws TestJSONException

      Returns:
      A character, or 0 if there are no more characters.
      Throws:
      TestJSONException - in case of a syntax error

    • nextString

      public String nextString(char quote) throws TestJSONException
      Return the characters up to the next close quote character. Backslash processing is done. The formal JSON format does not allow strings in single quotes, but an implementation is allowed to accept them.
