    • Method Detail

      • hasNext

        public boolean hasNext()
        Determine whether another token exists in this version.
        Returns:
        true if more tokens remain, false otherwise

      • next

        public void next()
        Move to the next token.
        Throws:
        java.util.NoSuchElementException - if there are no more tokens to iterate

      • length

        public int length()
        Get the length of the current token. If there is no current token, zero is returned.
        Returns:
        the length of the current token

      • isSeparator

        public boolean isSeparator()
        Determine if the current token is some kind of separator (a character or a zero-length alphabetical-to-numeric or numeric-to-alphabetical transition).
        Returns:
        true if the token is a separator, false otherwise

      • isPart

        public boolean isPart()
        Determine if the current token is some kind of part (alphabetical or numeric).
        Returns:
        true if the token is a separator, false otherwise

      • isEmptySeparator

        public boolean isEmptySeparator()
        Determine if the current token is an empty (or zero-length alphabetical-to-numeric or numeric-to-alphabetical) separator.
        Returns:
        true if the token is an empty separator, false otherwise

      • isNonEmptySeparator

        public boolean isNonEmptySeparator()
        Determine if the current token is a non-empty separator.
        Returns:
        true if the token is a non-empty separator, false otherwise

      • getSeparatorCodePoint

        public int getSeparatorCodePoint()
        Get the code point of the current separator. If the iterator is not positioned on a non-empty separator (i.e. isNonEmptySeparator() returns false), then an exception is thrown.
        Returns:
        the code point of the current separator
        Throws:
        java.lang.IllegalStateException - if the current token is not a non-empty separator

      • isAlphaPart

        public boolean isAlphaPart()
        Determine if the current token is an alphabetical part.
        Returns:
        true if the token is an alphabetical part, false otherwise

      • isNumberPart

        public boolean isNumberPart()
        Determine if the current token is a numeric part.
        Returns:
        true if the token is a numeric part, false otherwise

      • getAlphaPart

        public java.lang.String getAlphaPart()
        Get the current alphabetical part. If the iterator is not positioned on an alphabetical part (i.e. isAlphaPart() returns false), then an exception is thrown.
        Returns:
        the current alphabetical part
        Throws:
        java.lang.IllegalStateException - if the current token is not an alphabetical part

      • getNumberPartAsString

        public java.lang.String getNumberPartAsString()
        Get the current numeric part, as a String. If the iterator is not positioned on a numeric part (i.e. isNumberPart() returns false), then an exception is thrown.
        Returns:
        the current numeric part as a String
        Throws:
        java.lang.IllegalStateException - if the current token is not a numeric part

      • getNumberPartAsLong

        public long getNumberPartAsLong()
        Get the current numeric part, as a long. If the iterator is not positioned on a numeric part (i.e. isNumberPart() returns false), then an exception is thrown. If the value overflows the maximum value for a long, then only the low-order 64 bits of the version number value are returned.
        Returns:
        the current numeric part as a long
        Throws:
        java.lang.IllegalStateException - if the current token is not a numeric part

      • getNumberPartAsInt

        public int getNumberPartAsInt()
        Get the current numeric part, as an int. If the iterator is not positioned on a numeric part (i.e. isNumberPart() returns false), then an exception is thrown. If the value overflows the maximum value for an int, then only the low-order 32 bits of the version number value are returned.
        Returns:
        the current numeric part as an int
        Throws:
        java.lang.IllegalStateException - if the current token is not a numeric part

      • getNumberPartAsBigInteger

        public java.math.BigInteger getNumberPartAsBigInteger()
        Get the current numeric part, as a BigInteger. If the iterator is not positioned on a numeric part (i.e. isNumberPart() returns false), then an exception is thrown.
        Returns:
        the current numeric part as a BigInteger
        Throws:
        java.lang.IllegalStateException - if the current token is not a numeric part
