class IasIO[T](val inOut: InOut[T])

The view of an InOut for the TF

The view of an InOut for the TF

IasIO exposes only the InOut's methods that can be invoked by the TF hiding the methods meant for the internals of the IAS.

The IasIo reduces the risk of errors from misuse from the TF and simplify the API

IasIo is immutable.

Value parameters

inOut

The InOut to delegate

The ScalaTransferExecutor provides the interface for scala implementations of the transfer function.

The ScalaTransferExecutor provides the interface for scala implementations of the transfer function.

Value parameters

class TransferFunctionSetting(val className: String, val language: Value, templateInstance: Option[Int], threadFactory: ThreadFactory)

The settings for the transfer function are retrieved from the configuration (DB, XML, text file) and passed to the ComputingElement.

The settings for the transfer function are retrieved from the configuration (DB, XML, text file) and passed to the ComputingElement.

Objects of this class contain all the information to run the transfer function independently from the supported programming language (@see TransferFunctionLanguage).

At the present there 3 possible implementations of the transfer function in scala, java or python.

Java implementation requires to provide a java-style interface to developers for which we need to convert scala data structure to/from java. Scala implementations of the TF are therefore more performant (in principle).

For python TFs, we use jep (https://github.com/ninia/jep) that provides interoperability between java and python. For the python TFs, a java class is always loaded, PythonExecutorTF, that delegates to the python class whose name is in the className property

Value parameters

className:

The name of the java/scala/python class to run

language:

the programming language used to implement the TF

templateInstance:

the instance of the template if defined; if empty the ASCE is not generated out of a template

threadFactory:

The thread factory to async. run init and shutdown on the user provided TF object
