static long[]	doLongSplit(long left, long right, int expectSliceNumber)
static org.apache.commons.lang3.tuple.Pair<Character,Character>	getMinAndMaxCharacter(String aString)	获取字符串中的最小字符和最大字符（依据 ascii 进行判断）.要求字符串必须非空，并且为 ascii 字符串.
static BigInteger	stringToBigInteger(String aString, int radix)	由于只支持 ascii 码对应字符，所以radix 范围为[1,128]

Method Detail

doAsciiStringSplit

public static String[] doAsciiStringSplit(String left,
                                          String right,
                                          int expectSliceNumber)

doLongSplit

public static long[] doLongSplit(long left,
                                 long right,
                                 int expectSliceNumber)

doBigIntegerSplit

public static BigInteger[] doBigIntegerSplit(BigInteger left,
                                             BigInteger right,
                                             int expectSliceNumber)

stringToBigInteger

public static BigInteger stringToBigInteger(String aString,
                                            int radix)

由于只支持 ascii 码对应字符，所以radix 范围为[1,128]

getMinAndMaxCharacter

public static org.apache.commons.lang3.tuple.Pair<Character,Character> getMinAndMaxCharacter(String aString)

获取字符串中的最小字符和最大字符（依据 ascii 进行判断）.要求字符串必须非空，并且为 ascii 字符串. 返回的Pair，left=最小字符，right=最大字符.
