        Create instance of the NumberPattern
        Parameters:
        regex - Regular expression for the number parser
        radix - The radix that the pattern represents
        cutFromStart - Count of characters that will be cut from the beginning of a number by calling prepareNumber method.
        cutFromEnd - Count of characters that will be cut from the end of a number by calling prepareNumber method.

    • Method Detail

      • matches

        public boolean matches​(java.lang.String number)
        Determines if a number represented as String matches this NumberPattern.
        Parameters:
        number - the number String representation
        Returns:
        true if the number matches this pattern, false otherwise

      • getRadix

        public int getRadix()
        Get radix of this NumberPattern
        Returns:
        radix of this pattern

      • prepareNumber

        public java.lang.String prepareNumber​(java.lang.String number)
        Prepares the number for radix conversion.

        It formats given number into a form that does not contain any additional characters for radix recognition.

        For example, pattern 

        0x[0-9a-fA-F]+
        , representing hexadecimal number, contains some characters needed for pattern recognition, they are the first two (
        0x
        ).

        The numbers of left and right cut are defined in the constructor.

        Parameters:
        number - the number String representation
        Returns:
        String number prepared for radix conversion.
