All Implemented Interfaces:

PortInliner

public class HSPortInliner
extends java.lang.Object
implements PortInliner

A class that inlines methods on ports for HS models. This class creates a set of appropriately sized circular buffers for each channel in a particular composite actor. These buffers are referred to by static fields of the model. Inside each actor in the composite, an array of integer indexes into the circular buffer is generated for each port. Port method invocations where the channel index can be statically determined are replaced with references to the appropriate buffer in the model, and an index update instructions for the appropriate index in the actor. In cases where the channel cannot be statically determined for a given invocation point, e.g. a for loop over all of the channels of a trigger input port to read and discard the data, a second reference to each buffer exists in the actors. These references are in a array that can be indexed by the channel of a port, and are called "buffer references". Additionally, index fields and buffer references are also created for each port in the model for handling "inside" port methods... FIXME: currently we try to speed things up if the buffersize is only one by removing the index update overhead. Note that there are other optimizations that can be made here (for instance, if we can statically determine all the channel references (which is trivially true if there is only one channel), then there is no need to have the index or portbuffer arrays.
