static int com::sleepycat::util::UtfOps::bytesToChars (  byte[]  bytes, int  byteOffset, char[]  chars, int  charOffset, int  len, boolean  isByteLen )  throws IllegalArgumentException, IndexOutOfBoundsException [inline, static]

Converts byte arrays into character arrays. Parameters: bytes  the source byte data to convert byteOffset  the offset into the byte array at which to start the conversion chars  the destination array charOffset  the offset into chars at which to begin the copy len  the amount of information to copy into chars isByteLen  if true then len is a measure of bytes, otherwise len is a measure of characters Exceptions: IndexOutOfBoundsException  if a UTF character sequence at the end of the data is not complete. IllegalArgumentException  if an illegal UTF sequence is encountered. Definition at line 168 of file UtfOps.java.

static String com::sleepycat::util::UtfOps::bytesToString (  byte[]  bytes, int  offset, int  length )  throws IllegalArgumentException, IndexOutOfBoundsException [inline, static]

Converts byte arrays into strings. Parameters: bytes  the source byte data to convert offset  the offset into the byte array at which to start the conversion length  the number of bytes to be converted. Returns: the string. Exceptions: IndexOutOfBoundsException  if a UTF character sequence at the end of the data is not complete. IllegalArgumentException  if an illegal UTF sequence is encountered. Definition at line 256 of file UtfOps.java.

static void com::sleepycat::util::UtfOps::charsToBytes (  char[]  chars, int  charOffset, byte[]  bytes, int  byteOffset, int  charLength )  [inline, static]

Converts character arrays into byte arrays. Parameters: chars  the source character data to convert charOffset  the offset into the character array at which to start the conversion bytes  the destination array byteOffset  the offset into bytes at which to begin the copy charLength  the length of characters to copy into bytes Definition at line 219 of file UtfOps.java.

static int com::sleepycat::util::UtfOps::getByteLength (  char[]  chars, int  offset, int  length )  [inline, static]

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. offset  the first character to be converted. length  the number of characters to be converted. Returns: the byte length of the equivalent UTF data. Definition at line 70 of file UtfOps.java.

static int com::sleepycat::util::UtfOps::getByteLength (  char[]  chars  )  [inline, static]

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. Returns: the byte length of the equivalent UTF data. Definition at line 53 of file UtfOps.java.

static int com::sleepycat::util::UtfOps::getCharLength (  byte[]  bytes, int  offset, int  length )  throws IllegalArgumentException, IndexOutOfBoundsException [inline, static]

Returns the number of characters represented by the given UTF string. Parameters: bytes  the data containing the UTF string. offset  the first byte to be converted. length  the number of byte to be converted. Exceptions: IndexOutOfBoundsException  if a UTF character sequence at the end of the data is not complete. IllegalArgumentException  if an illegal UTF sequence is encountered. Definition at line 121 of file UtfOps.java.

static int com::sleepycat::util::UtfOps::getCharLength (  byte[]  bytes  )  throws IllegalArgumentException, IndexOutOfBoundsException [inline, static]

Returns the number of characters represented by the given UTF string. Parameters: bytes  the UTF string. Returns: the number of characters. Exceptions: IndexOutOfBoundsException  if a UTF character sequence at the end of the data is not complete. IllegalArgumentException  if an illegal UTF sequence is encountered. Definition at line 100 of file UtfOps.java.

static int com::sleepycat::util::UtfOps::getZeroTerminatedByteLength (  byte[]  bytes, int  offset )  throws IndexOutOfBoundsException [inline, static]

Returns the byte length of a null terminated UTF string, not including the terminator. Parameters: bytes  the data containing the UTF string. offset  the beginning of the string the measure. Exceptions: IndexOutOfBoundsException  if no zero terminator is found. Returns: the number of bytes. Definition at line 35 of file UtfOps.java.

static byte [] com::sleepycat::util::UtfOps::stringToBytes (  String  string  )  [inline, static]

Converts strings to byte arrays. Parameters: string  the string to convert. Returns: the UTF byte array. Definition at line 273 of file UtfOps.java.
