virtual void	read (const std::string &buf)
	Set the value to that of the string buf. Overrides base class to append a terminating '\0' character if buf doesn't end with '\0'.
Accessors

	Return a pointer to a copy of itself (deep copy). The caller owns this copy and is responsible to delete it!

Member Function Documentation

void Exiv2::AsciiValue::read (  const byte *  buf, long  len, ByteOrder  byteOrder = invalidByteOrder )  [virtual]

Read the value from a character buffer. Appends a terminating '\0' character if buf doesn't end with 0. Note: The byte order is required by the interface but not used by this method, so just use the default. Parameters: buf  Pointer to the data buffer to read from len  Number of bytes in the data buffer byteOrder  Byte order. Not needed. Reimplemented from Exiv2::StringValueBase.
