    Returns the substring from string str before count occurrences of the delimiter delim.

    Returns the substring from string str before count occurrences of the delimiter delim. If count is positive, everything the left of the final delimiter (counting from left) is returned. If count is negative, every to the right of the final delimiter (counting from the right) is returned. subStringIndex performs a case-sensitive match when searching for delim.

45.  def toByte(intWrapper: IntWrapper): Boolean
46.  def toByteExact(): Byte
47.  def toInt(intWrapper: IntWrapper): Boolean

    Parses this UTF8String(trimmed if needed) to int.

    Parses this UTF8String(trimmed if needed) to int.

    Note that, in this method we accumulate the result in negative format, and convert it to positive format at the end, if this string is not started with '-'. This is because min value is bigger than max value in digits, e.g. Integer.MAX_VALUE is '2147483647' and Integer.MIN_VALUE is '-2147483648'.

    This code is mostly copied from LazyInt.parseInt in Hive.

    Note that, this method is almost same as toLong, but we leave it duplicated for performance reasons, like Hive does.

    intWrapper

    If a valid int was parsed from this UTF8String, then its value would be set in intWrapper

    returns

    true if the parsing was successful else false

48.  def toIntExact(): Int

    Parses UTF8String(trimmed if needed) to int.

    Parses UTF8String(trimmed if needed) to int. This method is used when ANSI is enabled.

    returns

    If string contains valid numeric value then it returns the int value otherwise a NumberFormatException is thrown.

49.  def toLong(toLongResult: LongWrapper): Boolean

    Parses this UTF8String(trimmed if needed) to long.

    Parses this UTF8String(trimmed if needed) to long.

    Note that, in this method we accumulate the result in negative format, and convert it to positive format at the end, if this string is not started with '-'. This is because min value is bigger than max value in digits, e.g. Long.MAX_VALUE is '9223372036854775807' and Long.MIN_VALUE is '-9223372036854775808'.

    This code is mostly copied from LazyLong.parseLong in Hive.

    toLongResult

    If a valid long was parsed from this UTF8String, then its value would be set in toLongResult

    returns

    true if the parsing was successful else false

50.  def toLongExact(): Long

    Parses UTF8String(trimmed if needed) to long.

    Parses UTF8String(trimmed if needed) to long. This method is used when ANSI is enabled.

    returns

    If string contains valid numeric value then it returns the long value otherwise a NumberFormatException is thrown.

51.  def toLowerCase(): UTF8String

    Trims instances of the given trim string from both ends of this string.

    trimString

    the trim character string

    returns

    Trims space characters (ASCII 32) from both ends of this string.

    returns

    this string with no spaces at the start or end

60.  def trimAll(): UTF8String

    Trims whitespaces (<= ASCII 32) from both ends of this string.

    Trims whitespaces (<= ASCII 32) from both ends of this string.

    Note that, this method is the same as java's String#trim, and different from UTF8String#trim() which remove only spaces(= ASCII 32) from both ends.

    returns

    A UTF8String whose value is this UTF8String, with any leading and trailing white space removed, or this UTF8String if it has no leading or trailing whitespace.

61.  def trimLeft(trimString: UTF8String): UTF8String
