public class SequenceSource
extends MutableConnectedControlActor
implements OutputProducer

Encapsulates a sequence of flow items, with the last one generating the output for this meta-source.

-logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 

-name <java.lang.String> (property: name)
    The name of the actor.
    default: SequenceSource
 

-annotation <adams.core.base.BaseText> (property: annotations)
    The annotations to attach to this actor.
    default: 
 

-skip <boolean> (property: skip)
    If set to true, transformation is skipped and the input token is just forwarded 
    as it is.
    default: false
 

-stop-flow-on-error <boolean> (property: stopFlowOnError)
    If set to true, the flow gets stopped in case this actor encounters an error;
     useful for critical actors.
    default: false
 

-finish-before-stopping <boolean> (property: finishBeforeStopping)
    If enabled, actor first finishes processing all data before stopping.
    default: false
 

-actor <adams.flow.core.Actor> [-actor ...] (property: actors)
    All the actors that define this sequence.
    default:

SequenceSource

public SequenceSource()

Method Detail

globalInfo

public String globalInfo()

Returns a string describing the object.

Specified by:

globalInfo in interface GlobalInfoSupporter

Specified by:

globalInfo in class AbstractOptionHandler

Returns:

a description suitable for displaying in the gui

actorsTipText

public String actorsTipText()

Returns the tip text for this property.

Specified by:

actorsTipText in class MutableConnectedControlActor

Returns:

tip text for this property suitable for displaying in the GUI or for listing the options.

getActorHandlerInfo

public ActorHandlerInfo getActorHandlerInfo()

Returns some information about the actor handler, e.g., whether it can contain standalones and the actor execution.

Specified by:

getActorHandlerInfo in interface ActorHandler

Specified by:

getActorHandlerInfo in class AbstractControlActor

Returns:

the info

getOutputTokens

public List<Token> getOutputTokens()

Initializes m_OutputTokens if necessary and returns it.

Returns:

m_OutputTokens

addOutputToken

protected void addOutputToken(Token output)

Adds the given token to the list of available output tokens.

Parameters:

output - the token to add

See Also:

getOutputTokens()

newDirector

protected SequentialDirector newDirector()

Returns an instance of a director.

Overrides:

newDirector in class AbstractDirectedControlActor

Returns:

the director

generates

public Class[] generates()

Returns the class that the consumer accepts.

Specified by:

generates in interface OutputProducer

Returns:

the Class of objects that can be processed

output
