public class ByteFieldContainer

extends java.lang.Object

MMObjectNodes can contain Binary data. These BYTE fields can be retrieved, byt the node does not store them internally - nodes are cached, and caching large amounts of binary data is bad for performance. However, some classes keep a separate cache for binaries (i.e. Images). This class is meant to hold byte arrays while simultaneously keep data as to which object it is part of. This allows for caching and passing binary values between functions without loosing track of which image it is part of.
