Constructor Detail

MappingElementImpl

public MappingElementImpl()

Create new MappingElementImpl with no corresponding name. This constructor should only be used for cloning and archiving.

MappingElementImpl

public MappingElementImpl(String name)

Creates new MappingElementImpl with the corresponding name

Parameters:

name - the name of the element

Method Detail

getMessages

protected static final ResourceBundle getMessages()

Returns:

I18N message handler for this element

toString

public String toString()

Overrides Object's toString method to return the name of this mapping element.

Overrides:

toString in class Object

Returns:

a string representation of the object

equals

public boolean equals(Object obj)

Overrides Object's equals method by comparing the name of this mapping element with the name of the argument obj. The method returns false if obj does not have the same dynamic type as this mapping element.

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode

public int hashCode()

Overrides Object's hashCode method to return the hashCode of this mapping element's name.

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

firePropertyChange

protected void firePropertyChange(String name,
                                  Object o,
                                  Object n)

Fires property change event.

Parameters:

name - property name

o - old value

n - new value

fireVetoableChange

protected void fireVetoableChange(String name,
                                  Object o,
                                  Object n)
                           throws PropertyVetoException

Fires vetoable change event.

Parameters:

name - property name

o - old value

n - new value

Throws:

PropertyVetoException - when the change is vetoed by a listener

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener l)

Add a property change listener.

Specified by:

addPropertyChangeListener in interface MappingElement

Parameters:

l - the listener to add

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener l)

Remove a property change listener.

Specified by:

removePropertyChangeListener in interface MappingElement

Parameters:

l - the listener to remove

addVetoableChangeListener

public void addVetoableChangeListener(VetoableChangeListener l)

Add a vetoable change listener.

Specified by:

addVetoableChangeListener in interface MappingElement

Parameters:

l - the listener to add

removeVetoableChangeListener

public void removeVetoableChangeListener(VetoableChangeListener l)

Remove a vetoable change listener.

Specified by:

removeVetoableChangeListener in interface MappingElement

Parameters:

l - the listener to remove

getName

public String getName()

Get the name of this mapping element.

Specified by:

getName in interface MappingElement

Returns:

the name

setName

public void setName(String name)
             throws ModelException

Set the name of this mapping element.

Specified by:

setName in interface MappingElement

Parameters:

name - the name

Throws:

ModelException - if impossible

compareTo

public int compareTo(Object o)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. The specified object must be mapping element, meaning it must be an instance of class MappingElementImpl or any subclass. If not a ClassCastException is thrown. The order of MappingElementImpl objects is defined by the order of their names. Mapping elements without name are considered to be less than any named mapping element.

Specified by:

compareTo in interface Comparable

Parameters:

o - the Object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Throws:

ClassCastException - - if the specified object is null or is not an instance of MappingElementImpl
