 public RastaOperator() throws RemoteException

Methods

o getCmd 
 protected String[] getCmd()
Overrides:
getCmd in class ProcessOperator
o getInputType 
 public String getInputType() throws RemoteException
Should return the input type of the operator

Overrides:
getInputType in class Operator
o getOutputType 
 public String getOutputType() throws RemoteException
Should return the output type of the operator

Overrides:
getOutputType in class Operator
o opBlockSize 
 public int opBlockSize() throws RemoteException
Rasta output is approximately 2.5 times smaller than PCM. 64 bytes is the data for 20 ms.

Overrides:
opBlockSize in class ProcessOperator
o ipBlockSize 
 public int ipBlockSize() throws RemoteException
Input is PCM ULaw. 160 bytes is the data for 20ms. Since input can be from an RTP stream, this needs to be exact.

Overrides:
ipBlockSize in class ProcessOperator
o start 
 public void start(DescrOperator descrop)
start this operator running.

Overrides:
start in class ProcessOperator
