Field Detail

propertyChangeListeners

protected java.util.Vector propertyChangeListeners

List of PropertyChangeListeners registered for PropertyChangeEvents on this object.

Constructor Detail

BaseEngineProperties

protected BaseEngineProperties()

Class constructor.

Method Detail

getControlComponent

public java.awt.Component getControlComponent()

Obtains the AWT Component that provides the default user interface for setting the properties of the Engine associated with this object.

Specified by:

getControlComponent in interface javax.speech.EngineProperties

Returns:

an AWT Component to manipulate this object

reset

public abstract void reset()

Returns all properties to reasonable defaults for the Engine. A PropertyChangeEvent is issued for each property that changes as the reset takes effect.

Specified by:

reset in interface javax.speech.EngineProperties

addPropertyChangeListener

public void addPropertyChangeListener(java.beans.PropertyChangeListener listener)

Adds a PropertyChangeListener to the listener list.

Specified by:

addPropertyChangeListener in interface javax.speech.EngineProperties

Parameters:

listener - the PropertyChangeListener to add

removePropertyChangeListener

public void removePropertyChangeListener(java.beans.PropertyChangeListener listener)

Removes a PropertyChangeListener from the listener list.

Specified by:

removePropertyChangeListener in interface javax.speech.EngineProperties

Parameters:

listener - the PropertyChangeListener to remove

postPropertyChangeEvent

protected void postPropertyChangeEvent(java.lang.String propName,
                                       java.lang.Object oldValue,
                                       java.lang.Object newValue)

Generates a PropertyChangeEvent for an Object value and posts it to the event queue. Eventually firePropertyChangeEvent will be called by dispatchSpeechEvent as a result of this action.

Parameters:

propName - the name of the property

oldValue - the old value

newValue - the new value

See Also:

firePropertyChangeEvent(java.beans.PropertyChangeEvent), dispatchSpeechEvent(javax.speech.SpeechEvent)

postPropertyChangeEvent

protected void postPropertyChangeEvent(java.lang.String propName,
                                       float oldValue,
                                       float newValue)

Generates a PropertyChangeEvent for a float value and posts it to the event queue. Eventually firePropertyChangeEvent will be called by dispatchSpeechEvent as a result of this action.

Parameters:

propName - the name of the property

oldValue - the old value

newValue - the new value

See Also:

firePropertyChangeEvent(java.beans.PropertyChangeEvent), dispatchSpeechEvent(javax.speech.SpeechEvent)

postPropertyChangeEvent

protected void postPropertyChangeEvent(java.lang.String propName,
                                       int oldValue,
                                       int newValue)

Generates a PropertyChangeEvent for a int value and posts it to the event queue. Eventually firePropertyChangeEvent will be called by dispatchSpeechEvent as a result of this action.

Parameters:

propName - the name of the property

oldValue - the old value

newValue - the new value

See Also:

firePropertyChangeEvent(java.beans.PropertyChangeEvent), dispatchSpeechEvent(javax.speech.SpeechEvent)

postPropertyChangeEvent

protected void postPropertyChangeEvent(java.lang.String propName,
                                       boolean oldValue,
                                       boolean newValue)

Generates a PropertyChangeEvent for a boolean value and posts it to the event queue. Eventually firePropertyChangeEvent will be called by dispatchSpeechEvent as a result of this action.

Parameters:

propName - the name of the property

oldValue - the old value

newValue - the new value

See Also:

firePropertyChangeEvent(java.beans.PropertyChangeEvent), dispatchSpeechEvent(javax.speech.SpeechEvent)

firePropertyChangeEvent

public void firePropertyChangeEvent(java.beans.PropertyChangeEvent event)

Sends a PropertyChangeEvent to all PropertyChangeListeners registered with this object. Called by dispatchSpeechEvent.

Parameters:

event - the PropertyChangeEvent to send

See Also:

firePropertyChangeEvent(java.beans.PropertyChangeEvent), dispatchSpeechEvent(javax.speech.SpeechEvent)

dispatchSpeechEvent

public void dispatchSpeechEvent(javax.speech.SpeechEvent event)

Dispatches a PropertyChangeEvent. The dispatcher should notify all PropertyChangeListeners from this method. The SpeechEvent was added via the various post methods of this class.

Specified by:

dispatchSpeechEvent in interface SpeechEventDispatcher

Parameters:

event - the SpeechEvent containing a PropertyChangeEvent
