Method Detail

hex

public static String hex(char ch)

Convert a char to 4 hex uppercase digits. E.g., hex('a') => "0041".

hex

public static String hex(String s)

Convert a string to comma-separated groups of 4 hex uppercase digits. E.g., hex('ab') => "0041,0042".

hex

public static String hex(StringBuffer s)

Convert a string to comma-separated groups of 4 hex uppercase digits. E.g., hex('ab') => "0041,0042".

hex

public static StringBuffer hex(char ch,
                               StringBuffer output)

Convert a char to 4 hex uppercase digits. E.g., hex('a') => "0041". Append the output to the given StringBuffer.

hex

public static StringBuffer hex(int ch,
                               int width,
                               StringBuffer output)

Convert a integer to size width hex uppercase digits. E.g., hex('a', 4, str) => "0041". Append the output to the given StringBuffer. If width is too small to fit, nothing will be appended to output.

hex

public static String hex(int ch,
                         int width)

Convert a integer to size width (minimum) hex uppercase digits. E.g., hex('a', 4, str) => "0041". If the integer requires more than width digits, more will be used.

appendNumber

public static StringBuffer appendNumber(StringBuffer result,
                                        int n)

Append a number to the given StringBuffer in the radix 10 generating at least one digit.

appendNumber

public static StringBuffer appendNumber(StringBuffer result,
                                        int n,
                                        int radix,
                                        int minDigits)
                                 throws IllegalArgumentException

Append a number to the given StringBuffer in the given radix. Standard digits '0'-'9' are used and letters 'A'-'Z' for radices 11 through 36.

Parameters:

result - the digits of the number are appended here

n - the number to be converted to digits; may be negative. If negative, a '-' is prepended to the digits.

radix - a radix from 2 to 36 inclusive.

minDigits - the minimum number of digits, not including any '-', to produce. Values less than 2 have no effect. One digit is always emitted regardless of this parameter.

Returns:

a reference to result

Throws:

IllegalArgumentException

hex

public static String hex(long i,
                         int places)

Supplies a zero-padded hex representation of an integer (without 0x)

hex

public static String hex(long ch)

hex

public static StringBuffer hex(String s,
                               StringBuffer result)

Convert a string to comma-separated groups of 4 hex uppercase digits. E.g., hex('ab') => "0041,0042". Append the output to the given StringBuffer.
