INTERNAL API A GraphAssembly represents a small stream processing graph to be executed by the interpreter. Instances of this class **must not** be mutated after construction. The array OriginalAttributes may contain the attribute information of the original atomic module, otherwise it must contain a none (otherwise the enclosing module could not overwrite attributes defined in this array). The arrays Inlets and Outlets correspond to the notion of a *connection* in the GraphInterpreter. Each slot *i* contains the input and output port corresponding to connection *i*. Slots where the graph is not closed (i.e. ports are exposed to the external world) are marked with null values. For example if an input port p is exposed, then Outlets[p] will contain a null. The arrays InletOwners and OutletOwners are lookup tables from a connection id(the index of the slot) to a slot in the Stages array, indicating which stage is the owner of the given input or output port. Slots which would correspond to non-existent stages(where the corresponding port is null since it represents the currently unknown external context) contain the value Boundary. The current assumption by the infrastructure is that the layout of these arrays looks like this: +---------------------------------------+-----------------+ inOwners: | index to stages array | Boundary(-1) | +----------------+----------------------+-----------------+ ins: | exposed inputs | internal connections | nulls | +----------------+----------------------+-----------------+ outs: | nulls | internal connections | exposed outputs | +----------------+----------------------+-----------------+ outOwners: | Boundary(-1) | index to stages array | +----------------+----------------------------------------+ In addition, it is also assumed by the infrastructure that the order of exposed inputs and outputs in the corresponding segments of these arrays matches the exact same order of the ports in the Shape.
