Enclosing class:

CloneableOpenSupport

public static interface CloneableOpenSupport.Env

extends Serializable

Abstract interface that is used by CloneableOpenSupport to talk to outside world.

Field Summary

static String	PROP_MODIFIED that is fired when the objects wants to mark itself modified or not modified.
static String	PROP_VALID that is fired when the objects wants to mark itself as invalid, so all components should be closed.

Method Summary

void	addPropertyChangeListener(PropertyChangeListener l) Adds property listener.
void	addVetoableChangeListener(VetoableChangeListener l) Adds veto listener.
CloneableOpenSupport	findCloneableOpenSupport() Method that allows environment to find its cloneable open support.
boolean	isModified() Test whether the object is modified or not.
boolean	isValid() Test whether the support is in valid state or not.
void	markModified() Support for marking the environement modified.
void	removePropertyChangeListener(PropertyChangeListener l) Removes property listener.
void	removeVetoableChangeListener(VetoableChangeListener l) Removes veto listener.
void	unmarkModified() Reverse method that can be called to make the environment unmodified.

Field Detail

PROP_VALID

public static final String PROP_VALID

that is fired when the objects wants to mark itself as invalid, so all components should be closed.

PROP_MODIFIED

public static final String PROP_MODIFIED

that is fired when the objects wants to mark itself modified or not modified.

Method Detail

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

Adds property listener.

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)

Removes property listener.

addVetoableChangeListener

public void addVetoableChangeListener(VetoableChangeListener l)

Adds veto listener.

removeVetoableChangeListener

public void removeVetoableChangeListener(VetoableChangeListener l)

Removes veto listener.

isValid

public boolean isValid()

Test whether the support is in valid state or not. It could be invalid after deserialization when the object it referenced to does not exist anymore.

Returns:

true or false depending on its state

isModified

public boolean isModified()

Test whether the object is modified or not.

Returns:

true if the object is modified

markModified

public void markModified()
                  throws IOException

Support for marking the environement modified.

Throws:

IOException - if the environment cannot be marked modified (for example when the file is readonly), when such exception is the support should discard all previous changes

unmarkModified

public void unmarkModified()

Reverse method that can be called to make the environment unmodified.

findCloneableOpenSupport

public CloneableOpenSupport findCloneableOpenSupport()

Method that allows environment to find its cloneable open support.
