Class AbstractSimpleParallelTaskImpl

java.lang.Object
  fr.cnes.sirius.validate.parallel.AbstractSimpleParallelTaskImpl

All Implemented Interfaces:

ParallelTask, Callable<ParallelResult>

public abstract class AbstractSimpleParallelTaskImpl
extends Object
implements ParallelTask

Simple, abstract implementation for a ParallelTask. Serves as a base for generic, simple implementations of ParallelTask, or as a starting example for other implementations. Provides simple implementations for getTaskLabel() and getTaskInfo(), which may be enough for most cases. The developer extending this class only needs to provide the callImpl() method.

Constructor Detail

AbstractSimpleParallelTaskImpl

protected AbstractSimpleParallelTaskImpl(int iid)

Constructor with instance id parameter.

Parameters:

iid - the instance id, an integer. Identifies the task instance in the getTaskInfo string, has otherwise no use.

Method Detail

getTaskLabel

public String getTaskLabel()

Description copied from interface: ParallelTask

Returns a label identifying the task "class". It's the same for all instances of the task.

Specified by:

getTaskLabel in interface ParallelTask

Returns:

the task label

getTaskInfo

public String getTaskInfo()

Description copied from interface: ParallelTask

Returns human-readable info on the status of the task. Is intended to change depending on the current state of the task.

Specified by:

getTaskInfo in interface ParallelTask

Returns:

the status of the task.

call

public ParallelResult call()

Specified by:

call in interface ParallelTask

Specified by:

call in interface Callable<ParallelResult>

callImpl

protected abstract ParallelResult callImpl()

Call implementation to be provided by the implementing class. The implementation only has to handle the task in itself, and returning the result (the result is saved by the base class).

Returns:

a ParallelResult instance

getResult

public ParallelResult getResult()

Description copied from interface: ParallelTask

Asynchronous getter for the results. Is meant to be called after call to call(), and call() has ended. Otherwise behavior is unpredictable.

Specified by:

getResult in interface ParallelTask

Returns:

the same ParallelResult object already returned by call()

getId

public int getId()

Returns:

the id

getCallThreadName

protected String getCallThreadName()

Returns:

the callThreadName
