public String getSystemID();


returns Identifier of this Functionality

public void notifyObservers();

If this object has changed, as indicated by the hasChanged method, then notify all of its observers and then call the clearChanged method to indicate that this object has no longer changed.

Each observer has its update method called with two arguments: this observable object and null. In other words, this method is equivalent to:

notifyObservers(null)

public void notifyObservers(Object arg);

If this object has changed, as indicated by the hasChanged method, then notify all of its observers and then call the clearChanged method to indicate that this object has no longer changed.

Each observer has its update method called with two arguments: this observable object and the arg argument.

• arg any object.

public synchronized boolean hasChanged();

Tests if this object has changed.
returns true if and only if the setChanged method has been called more recently than the clearChanged method on this object; false otherwise.

public synchronized int countObservers();

Returns the number of observers of this Observable object.
returns the number of observers of this object.

public FWAbstractFunctionality getFunctionality();

Returns the number of observers of this Observable object.
returns the number of observers of this object.

public FWObservable clone(); // Overrides java.lang.Object

Returns the number of observers of this Observable object.
returns the number of observers of this object.

public boolean getBooleanParameterValue(String aParamKey, boolean aDefault);

• aParamKey
• aDefault

returns boolean parameter value

public void removeParameter(String aElement);

• aElement

public void putAllParameters(Map aParamMap);

• aParamMap

public boolean isParameterSet(String aKey);

• aKey

returns true, is the parameter is set, otherwise returns false

public String toString(); // Overrides java.lang.Object

protected synchronized void setChanged();

Marks this Observable object as having been changed; the hasChanged method will now return true.

protected synchronized void clearChanged();

Indicates that this object has no longer changed, or that it has already notified all of its observers of its most recent change, so that the hasChanged method will now return false. This method is called automatically by the notifyObservers methods.
