public class ClearCallableDisplay
extends AbstractCallableActor
implements ControlActor, InputConsumer, OutputProducer

Clears the referenced callable graphical actor whenever a token passes through.

Input/output:
- accepts:
adams.flow.core.Unknown
- generates:
adams.flow.core.Unknown

-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: ClearCallableDisplay
 

-annotation <adams.core.base.BaseAnnotation> (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
 

-callable <adams.flow.core.CallableActorReference> (property: callableName)
    The name of the callable actor to use.
    default: unknown
 

-optional <boolean> (property: optional)
    If enabled, then the callable actor is optional, ie no error is raised if 
    not found, merely ignored.
    default: false

Field Detail

m_InputToken

protected Token m_InputToken

the input token.

m_OutputToken

protected Token m_OutputToken

the output token.

Constructor Detail

ClearCallableDisplay

public ClearCallableDisplay()

Default constructor.

ClearCallableDisplay

public ClearCallableDisplay(CallableActorReference name)

Allows setting the callable name.

Parameters:

name - the reference to use

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

setUpCallableActor

protected String setUpCallableActor()

Configures the callable actor.

Overrides:

setUpCallableActor in class AbstractCallableActor

Returns:

null if successful, otherwise error message

accepts

public Class[] accepts()

Returns the class that the consumer accepts.

Specified by:

accepts in interface InputConsumer

Returns:

adams.flow.core.Unknown.class

input

public void input(Token token)

Does nothing.

Specified by:

input in interface InputConsumer

Parameters:

token - the token to accept and process

hasInput

public boolean hasInput()

Returns whether an input token is currently present.

Specified by:

hasInput in interface InputConsumer

Returns:

true if input token present

currentInput

public Token currentInput()

Returns the current input token, if any.

Specified by:

currentInput in interface InputConsumer

Returns:

the input token, null if none present

executeCallableActor

protected String executeCallableActor()

Executes the callable actor. Derived classes might need to override this method to ensure atomicity.

Specified by:

executeCallableActor in class AbstractCallableActor

Returns:

null if no error, otherwise error message

generates

public Class[] generates()

Returns the class of objects that it generates.

Specified by:

generates in interface OutputProducer

Returns:

adams.flow.core.Unknown.class

execute

public String execute()

Executes the flow item.

Specified by:

execute in interface Actor

Overrides:

execute in class AbstractActor

Returns:

null if everything is fine, otherwise error message

output

public Token output()

Returns the generated token.

Specified by:

output in interface OutputProducer

Returns:

the generated token

hasPendingOutput

public boolean hasPendingOutput()

Checks whether there is pending output to be collected after executing the flow item.

The method is not allowed allowed to return "true" before the actor has been executed. For actors that return an infinite number of tokens, the m_Executed flag can be returned.

Specified by:

hasPendingOutput in interface OutputProducer

Returns:

true if there is pending output
