    • FormatTokenizer

      public FormatTokenizer(String format, char c1, char c2)
      The constructor that defines the string called format from which the tokens will be extracted, and the two characthers that delimit the token.
      A token can be of two types:
      • formatted: the part of the format that starts with the first input character and ends with the second input character. The token contains the two delimiter characters;
      • constant: the part of the format between two formatted tokens. This token doesn't contains the delimiter characters.
      For example the string
      "{0{Someone has filled}{| has filled}{P||Jane Doe has filled}{L||Baby Doe has filled}} the bath tub{1{}{ of |}}"
      contains a first formatted token ("{0{Someone has filled}{| has filled} {P||Jane Doe has filled}{L||Baby Doe has filled}}"), a first constant token (" the bath tub") and a second formatted token ("{1{}{ of |}}").
      Parameters:
      format - The string to elaborate containing the tokens.
      c1 - The first delimiter character.
      c2 - The second delimiter character.

  • Method Details

    • hasNext

      public boolean hasNext()
      Check if there are still tokens to analyze.
      Returns:
      The boolean to indicate if there are still tokens.

    • next

      public String next()
      Locate and return the next token to analyze. See the constructor FormatTokenizer(format,c1,c2) to understand how a token is defined.
      Returns:
      The string containing the next token.

    • isFormat

      public boolean isFormat(String s)
      Return if the string passed as input is a formatted string. For formatted string we mean a string that starts with the first delimiter character and ends with the second delimiter character.
      Parameters:
      s - The string to check if it is formatted.
      Returns:
      Return the boolean to understand if the string is formatted. Obviously "true" means that the string is formatted, "false" means no.
