public class CopyGlobalSink
extends AbstractCopyGlobalActor
implements InputConsumer

Copies a global sink to consume the tokens.

Valid options are:

-D <int> (property: debugLevel)
    The greater the number the more additional info the scheme may output to 
    the console (0 = off).
    default: 0
    minimum: 0
 

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

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

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

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

-global <adams.flow.core.GlobalActorReference> (property: globalName)
    The name of the global actor to use.
    default: unknown

Method Detail

globalInfo

public String globalInfo()

Returns a string describing the object.

Specified by:

globalInfo in class AbstractOptionHandler

Returns:

a description suitable for displaying in the gui

findGlobalActor

protected AbstractActor findGlobalActor()

Tries to find the global actor referenced by its global name. Makes sure that the actor produces output.

Overrides:

findGlobalActor in class AbstractCopyGlobalActor

Returns:

the global actor or null if not found

backupState

protected Hashtable<String,Object> backupState()

Backs up the current state of the actor before update the variables.

Overrides:

backupState in class AbstractActor

Returns:

the backup

restoreState

protected void restoreState(Hashtable<String,Object> state)

Overrides:

restoreState in class AbstractActor

Parameters:

state - the backup of the state to restore from

reset

protected void reset()

Resets the scheme.

Overrides:

reset in class AbstractActor

accepts

input

public void input(Token token)

The method that accepts the input token and then processes it.

Specified by:

input in interface InputConsumer

Parameters:

token - the token to accept and process

executeGlobalActor

protected String executeGlobalActor()

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

Specified by:

executeGlobalActor in class AbstractCopyGlobalActor

Returns:

null if no error, otherwise error message
