public class ByteDataAccessSimple extends ByteDataAccessBase
ByteDataAccess accMy = new ByteDataAccessSimple(data); //we have not head data addMy.addChild(anyChild); //but there is a structure with children
Use this class as reference to access to any byte position:ByteDataAccessSimple accMy = new ByteDataAccessSimple(data); //any access to byte data necessary accMy.setIntVal(ix, 3, value); //sets the int value with 24 bit, it is an example float var = accMy.getFloatVal(24); //gets the bytes from position 24 and present them as float.In that case you can add children too, there are added from position 0. But it is not a good style to mix the both aproaches.

ByteDataAccessSimple(byte[], boolean, int) are documented with 'filled Buffer'
but they had clean it. Now correct adequate documentation.
