dsg.smart
Class SMBase

java.lang.Object
  dsg.smart.SMBase

All Implemented Interfaces:

StreamModule

Direct Known Subclasses:

DoubleSink, SinSource

public abstract class SMBase

extends java.lang.Object

implements StreamModule

Base class useful in writing Stream Modules.

Constructor Summary

SMBase(int numInputs, int numOutputs)

Method Summary

java.io.InputStream	getInput(int i) Returns the stream attached to the ith input.
int	getNumInputs() How many inputs does this stream module have?
int	getNumOutputs() How many outputs does this stream module have?
java.io.OutputStream	getOutput(int i) Returns the output stream attached to the ith output.
void	setInput(int i, java.io.InputStream fin) Assigns input stream --- called by MIT code when connecting stream modules.
void	setOutput(int i, java.io.OutputStream fout) Assigns output stream --- called by MIT code when connecting stream modules.
void	stop() Generally called from a separate thread from run().

Method Detail

getNumInputs

public int getNumInputs()

Description copied from interface: StreamModule

How many inputs does this stream module have?

Specified by:

getNumInputs in interface StreamModule

getNumOutputs

public int getNumOutputs()

Description copied from interface: StreamModule

How many outputs does this stream module have?

Specified by:

getNumOutputs in interface StreamModule

setInput

public void setInput(int i,
                     java.io.InputStream fin)

Assigns input stream --- called by MIT code when connecting stream modules.

Specified by:

setInput in interface StreamModule

getInput

public java.io.InputStream getInput(int i)

Description copied from interface: StreamModule

Returns the stream attached to the ith input.

Specified by:

getInput in interface StreamModule

setOutput

public void setOutput(int i,
                      java.io.OutputStream fout)

Assigns output stream --- called by MIT code when connecting stream modules.

Specified by:

setOutput in interface StreamModule

getOutput

public java.io.OutputStream getOutput(int i)

Description copied from interface: StreamModule

Returns the output stream attached to the ith output.

Specified by:

getOutput in interface StreamModule

stop

public void stop()

Description copied from interface: StreamModule

Generally called from a separate thread from run(). Cleans up by closing all upstream and downstream pipes, thus causing an exception in run(), which will then exit.

Specified by:

stop in interface StreamModule
