trait JavaTransfer[T] extends ComputingElement[T]

JavaTransfer calls the java transfer function provided by the user.

Note that the Validity of the output is not set by the transfer function but automatically implemented by the ASCE

Members list

Value members

Concrete methods

Initialize the scala transfer function

Value parameters

inputsInfo: The IDs and types of the inputs
instance: the instance
outputInfo: The Id and type of thr output

Attributes

scala data structs need to be converted before invoking the java code.

Inherited methods

ACK the alarm produced by the TF of the ASCE.

This function should be executed only if the type of the output is an alarm so in that case an error message is logged but the TF is not marked as broken. The ratio behind this choice is that the ACK is a command coming from outside: ACKing a value that is not an alarm is an error produced somewhere else that should be reported but not impact the functioning of the ASCE.

The function updates the value of the last produced output. This value will be passed to the TF the next time it is run because the inputs changed.

Attributes

Returns: true if the alarm has been acknowledged, false otherwise
Inherited from:: ComputingElement

Expose the actual state of this ASCE

Attributes

Returns: The state of the ASCE
Inherited from:: ComputingElement

Initialize the object.

This method must be executed only once before running the TF.

If the initialization fails, the state of the object changes to broken.

Attributes

Returns: The state of the ASCE after the initialization
Inherited from:: ComputingElement

Getter for the private _output

This method return the last calculated output.

Use getOutputWithUpdatedValidity() if you want the updated with an updated validity.

Attributes

Returns: the last calculated output
Inherited from:: ComputingElement

shutdown>/code> must be executed to free the resources of a ComputingElement that later on can be cleanly destroyed.

 One of the tasks of this method is to stop the timer thread to update the output i.e. to execute the transfer function.
