| public void | read(java.nio.ByteBuffer byteBuffer)This reads a frame body from its file into the appropriate FrameBody class
Read the data from the given file into this datatype. The file needs to
have its file pointer in the correct location. The size as indicated in the
header is passed to the frame constructor when reading from file.
int size = getSize();
//Allocate a buffer to the size of the Frame Body and read from file
byte[] buffer = new byte[size];
byteBuffer.get(buffer);
//Offset into buffer, incremented by length of previous MP3Object
int offset = 0;
//Go through the ObjectList of the Frame reading the data into the
//correct datatype.
AbstractDataType object;
Iterator<AbstractDataType> iterator = objectList.listIterator();
while (iterator.hasNext())
{
//The read has extended further than the defined frame size
if (offset > (size - 1))
{
throw new InvalidTagException("Invalid size for Frame Body");
}
//Get next Object and load it with data from the Buffer
object = iterator.next();
object.readByteArray(buffer, offset);
//Increment Offset to start of next datatype.
offset += object.getSize();

currently at.
