Deprecated.

It is preferable to declare the rate parameters directly in the actors, instead of using this class. This allows the dependence of rates to be understood by various SDF schedulers.

@Deprecated
public final class SDFIOPort
extends TypedIOPort

This class extends IOPort with convenience methods for handling the token production and consumption rates. These are merely convenience methods, as the pertinent attributes can be added to any IOPort and the SDF domain will respect them.

It is not recommended to use this port as a port for composite actors because the presence of the rate parameters will prevent the inner SDF scheduler from propagating it rates to the outside. That is, if the parameters are present, the scheduler does not override them.

          throws IllegalActionException

Deprecated.

Construct a port in the specified workspace with an empty string as a name. You can then change the name with setName(). If the workspace argument is null, then use the default workspace. The object is added to the workspace directory. Increment the version number of the workspace.

Parameters:

Construct an SDFIOPort with a containing actor and a name that is neither an input nor an output. The specified container must implement the Actor interface, or an exception will be thrown.

Parameters:

container - The container actor.

name - The name of the port.

Throws:

IllegalActionException - If the port is not of an acceptable class for the container, or if the container does not implement the Actor interface.

                 NameDuplicationException

Deprecated.

Construct an SDFIOPort with a container and a name that is either an input, an output, or both, depending on the third and fourth arguments. The specified container must implement the Actor interface or an exception will be thrown.

Parameters:

container - The container actor.

name - The name of the port.

isInput - True if this is to be an input port.

isOutput - True if this is to be an output port.

Throws:

IllegalActionException - If the port is not of an acceptable class for the container, or if the container does not implement the Actor interface.

NameDuplicationException - If the name coincides with a port already in the container.

Method Detail

clone

public java.lang.Object clone(Workspace workspace)
                       throws java.lang.CloneNotSupportedException

Clone the port into the specified workspace. This calls the base class and then creates new parameters. The new port will have the same parameter values as the old.

Overrides:

clone in class TypedIOPort

Parameters:

workspace - The workspace for the new object.

Returns:

A new SDFIOPort.

Throws:

java.lang.CloneNotSupportedException - If one of the attributes cannot be cloned.

Deprecated.

Get the number of tokens that are consumed on every channel of this port.

Returns:

The number of tokens consumed on this port, as specified in the tokenConsumptionRate Parameter.

Throws:

IllegalActionException - If calling getToken() throws it.

See Also:

setTokenConsumptionRate(int)

getTokenInitProduction

public int getTokenInitProduction()
                           throws IllegalActionException

Deprecated.

Get the number of tokens that are produced on this port during initialization.

Returns:

The number of tokens produced on the port, as specified in the tokenInitProduction parameter.

Returns:

The number of tokens produced on the port, as specified in the tokenProductionRate parameter.

Throws:

IllegalActionException - If calling getToken() throws it.

See Also:

setTokenProductionRate(int)

setInput

public void setInput(boolean isInput)
              throws IllegalActionException

Deprecated.

Set whether or not this port is an input. In addition to the base class operation, set the port rate parameters to reasonable values. If setting the port to be an input, then set the consumption rate to be 1. If setting the port to not be an input, then set the consumption rate to be 0.

Overrides:

setInput in class IOPort

Parameters:

isInput - True to make the port an input.
