Part of Ma Serializer
This class encapsulates a single object into its byteArray. The 0-based buffer positions of my fields are:
0 = oid (6 bytes)
6 = physicalSize (4 bytes)
10 = control-fields2 (1 byte)
bit 1 =
For MethodContextBuffers, 0 if small-frame, 1 = largeFrame.
For CompiledMethodBuffers, 0 = Cog header, 1 = spurHeader.
11 = filler (2 bytes)
13 = control-fields (1 byte)
4 bits (low-order) = bufferType (logical-type indicator of one of my subclasses)
4 bits (high-order) = indexed position into my class' #bpMaps Array, this value 0-15 (so +1 for access), the attribute-map Dictionary,
mapping each attribute Symbol (i.e., #oid) to its bufferPosition.
This allows advanced users like Magma to add its fields without interfering into the simpler nature of Ma object serialization.
bpMaps:
at: 0 = Ma object serialization minimum.
at: 1 = Magma-added fields
14 = classId (2 bytes)
