Parameters:   bytes - the source byte data to convert Parameters:   offset - the offset into the byte array at whichto start the conversion Parameters:   length - the number of bytes to be converted. public static  void charsToBytes(char[] chars, int charOffset, byte[] bytes, int byteOffset, int charLength)      Converts character arrays into byte arrays. public static  int getByteLength(char[] chars)      Returns the byte length of the UTF string that would be created by converting the given characters to UTF. Parameters:   chars - the characters that would be converted. public static  int getByteLength(char[] chars, int offset, int length)      Returns the byte length of the UTF string that would be created by converting the given characters to UTF. Parameters:   chars - the characters that would be converted. Parameters:   offset - the first character to be converted. Parameters:   length - the number of characters to be converted. public static  int getCharLength(byte[] bytes)      Returns the number of characters represented by the given UTF string. Parameters:   bytes - the UTF string. public static  int getCharLength(byte[] bytes, int offset, int length)      Returns the number of characters represented by the given UTF string. public static  int getZeroTerminatedByteLength(byte[] bytes, int offset)      Returns the byte length of a null terminated UTF string, not including the terminator. Parameters:   bytes - the data containing the UTF string. Parameters:   offset - the beginning of the string the measure. throws:   IndexOutOfBoundsException - if no zero terminator is found. public static  byte[] stringToBytes(String string)      Converts strings to byte arrays. Parameters:   string - the string to convert. Method Detail bytesToChars public static int bytesToChars(byte[] bytes, int byteOffset, char[] chars, int charOffset, int len, boolean isByteLen) throws IllegalArgumentException, IndexOutOfBoundsException(Code) Converts byte arrays into character arrays. Parameters:   bytes - the source byte data to convert Parameters:   byteOffset - the offset into the byte array at whichto start the conversion Parameters:   chars - the destination array Parameters:   charOffset - the offset into chars at which to begin the copy Parameters:   len - the amount of information to copy into chars Parameters:   isByteLen - if true then len is a measure of bytes, otherwiselen is a measure of characters throws:   IndexOutOfBoundsException - if a UTF character sequence at the endof the data is not complete. throws:   IllegalArgumentException - if an illegal UTF sequence isencountered. bytesToString public static String bytesToString(byte[] bytes, int offset, int length) throws IllegalArgumentException, IndexOutOfBoundsException(Code) Converts byte arrays into strings. Parameters:   bytes - the source byte data to convert Parameters:   offset - the offset into the byte array at whichto start the conversion Parameters:   length - the number of bytes to be converted. the string. throws:   IndexOutOfBoundsException - if a UTF character sequence at the endof the data is not complete. throws:   IllegalArgumentException - if an illegal UTF sequence isencountered. charsToBytes public static void charsToBytes(char[] chars, int charOffset, byte[] bytes, int byteOffset, int charLength)(Code) Converts character arrays into byte arrays. Parameters:   chars - the source character data to convert Parameters:   charOffset - the offset into the character array at whichto start the conversion Parameters:   bytes - the destination array Parameters:   byteOffset - the offset into bytes at which to begin the copy Parameters:   charLength - the length of characters to copy into bytes getByteLength public static int getByteLength(char[] chars)(Code) Returns the byte length of the UTF string that would be created by converting the given characters to UTF. Parameters:   chars - the characters that would be converted. the byte length of the equivalent UTF data. getByteLength public static int getByteLength(char[] chars, int offset, int length)(Code) Returns the byte length of the UTF string that would be created by converting the given characters to UTF.
