public class PythonExecutorTF<T>
extends JavaTransferExecutor<T>

Execution of TF in python is orchestrated by objects of this class: when there is a python TF, this transfer function implementation is executed: PythonExecutorTF delegates method execution to the python code through jep. That means that when python language for the TF is set in the configuration, this class is always loaded by the ASCE. Objects of this class then build the python object to which all the calls from ASCE are ultimately delegated.

Constructor Details

PythonExecutorTF

public PythonExecutorTF(String cEleId,
 String cEleRunningId,
 long validityTimeFrame,
 Properties props,
 String pythonClassName)
                 throws Exception

Constructor. This constructor differs from the other TFs because it needs to know the name of the python class to load.

Parameters:

cEleId - : The id of the ASCE

cEleRunningId - : the running ID of the ASCE

validityTimeFrame - : The time frame (msec) to invalidate monitor points

props - : The properties for the executor

pythonClassName - : The name of the python class to which to delegate

Throws:

Exception

Method Details

eval

public IasIOJ<T> eval(Map<String,IasIOJ<?>> compInputs,
 IasIOJ<T> actualOutput)
               throws Exception

Run the TF by delegating to the python implementation in th eproper thread

Specified by:

eval in class JavaTransferExecutor<T>

Parameters:

compInputs - : the inputs to the ASCE

actualOutput - : the actual output of the ASCE

Returns:

the new output

Throws:

Exception

initialize

public void initialize(Set<org.eso.ias.asce.transfer.IasioInfo> inputsInfo,
 org.eso.ias.asce.transfer.IasioInfo outputInfo)
                throws Exception

Description copied from class: JavaTransferExecutor

Initialize the transfer function

Specified by:

initialize in class JavaTransferExecutor<T>

Parameters:

inputsInfo - The IDs and types of the inputs

outputInfo - The Id and type of thr output

Throws:

Exception - in case of errors

shutdown

public void shutdown()
              throws Exception

Description copied from class: TransferExecutor

Shuts down the BehaviorRunner when the IAS does not need it anymore. This life cycle method is called last, to clean up the resources. It is supposed to return quickly, even if not mandatory.

Specified by:

shutdown in class TransferExecutor

Throws:

Exception - In case of error shutting down
