DefaultGestureObject

public DefaultGestureObject()

Method Detail

setAuthor

public void setAuthor(String a)

Description copied from interface: GestureObject

emits property change for property AUTHOR_PROP

Specified by:

setAuthor in interface GestureObject

getAuthor

public String getAuthor()

Specified by:

getAuthor in interface GestureObject

setParent

public void setParent(GestureContainer p)

Description copied from interface: GestureObject

emits property change for property PARENT_PROP

Specified by:

setParent in interface GestureObject

getParent

public GestureContainer getParent()

Specified by:

getParent in interface GestureObject

setEnabled

public void setEnabled(boolean on)

Description copied from interface: GestureObject

emits property change for property ENABLED_PROP

Specified by:

setEnabled in interface GestureObject

isEnabled

public boolean isEnabled()

Specified by:

isEnabled in interface GestureObject

hasProperty

public boolean hasProperty(String name)

Description copied from interface: GestureObject

Returns whether the object has the current property set

Specified by:

hasProperty in interface GestureObject

setProperty

public void setProperty(String name,
                        Object value)

Description copied from interface: GestureObject

Set the named property to a value. Null is not allowed as a key or value.

Specified by:

setProperty in interface GestureObject

unsetProperty

public void unsetProperty(String name)

Description copied from interface: GestureObject

Unset the property. Unsetting an already unset property has no effect. Predefined properties (e.g., author and enabled) cannot be removed and attempting to do so will result in an error.

Specified by:

unsetProperty in interface GestureObject

getProperty

public Object getProperty(String name)

Description copied from interface: GestureObject

Get the value of the named property (or null if it is not set).

Specified by:

getProperty in interface GestureObject

clone

public Object clone()

Deep-copies properties. Note that a clone does not have a parent (since the parent doesn't have the clone as a child).

Specified by:

clone in interface GestureObject

Overrides:

clone in class Object

readProperties

public void readProperties(TokenReader reader)
                    throws IOException,
                           ParseException

writeProperties

public void writeProperties(Writer writer)
                     throws IOException

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Description copied from interface: GestureObject

Listen for all propertyChangeEvents

Specified by:

addPropertyChangeListener in interface GestureObject

addPropertyChangeListener

public void addPropertyChangeListener(String propertyName,
                                      PropertyChangeListener listener)

Description copied from interface: GestureObject

Listen for propertyChangeEvents for a particular property

Specified by:

addPropertyChangeListener in interface GestureObject

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Description copied from interface: GestureObject

Stop listening for all propertyChangeEvents

Specified by:

removePropertyChangeListener in interface GestureObject

removePropertyChangeListener

public void removePropertyChangeListener(String propertyName,
