Method Details

receiveResponseData

public void receiveResponseData(String taskId,
 long timestamp,
 byte[] data)

Description copied from interface: ResponseReceivingComponent

This method is called if a response is received from the system.

Parameters:

taskId - the id of the task

timestamp - the time at which the response has been received from the system

data - the data received from a data generator

receiveExpectedResponseData

public void receiveExpectedResponseData(String taskId,
 long timestamp,
 byte[] data)

Description copied from interface: ExpectedResponseReceivingComponent

This method is called if an expected response is received from a task generator component.

Parameters:

taskId - the id of the task

timestamp - the time at which the task has been sent to the system

data - the data received from a task generator

putResult

public void putResult(boolean isExpectedResult,
 String taskId,
 long timestamp,
 byte[] data)

Adds the given result to the map of results.

Parameters:

isExpectedResult - true if the result has been received from a task generator, i.e., is the expected result for a task

taskId - id of the task

timestamp - time stamp for the task result

data - the result

createIterator

protected Iterator<ResultPair> createIterator()

Description copied from class: AbstractEvaluationStorage

Creates a new iterator that iterates over the response pairs.

Specified by:

createIterator in class AbstractEvaluationStorage

Returns:

a new iterator or null if an error occurred
