Javadoc

Similar to the ByteArrayOutputStream, with the exception that we can prepend an header. e.g. you write some data and you want to prepend an header that contains the data len or cksum.

 
ByteSlot slot = new ByteSlot(); 
// write data 
slot.write(...); 
slot.write(...); 
// write header with the size of the written data 
slot.markHead(); 
slot.write(Bytes.toBytes(slot.size())); 
// flush to stream as [header, data] 
slot.writeTo(stream);
