MappingMemberElementImpl

• java.lang.Object
  • MappingElementImpl

Fields Summary
MappingClassElement	_declaringClass the class to which this element belongs

Constructors Summary
public MappingMemberElementImpl() Create new MappingMemberElementImpl with no corresponding name or declaring class. This constructor should only be used for cloning and archiving. this(null, null);
public MappingMemberElementImpl(String name, MappingClassElement declaringClass) Create new MappingMemberElementImpl with the corresponding name and declaring class. param name the name of the element param declaringClass the class to attach to super(name); _declaringClass = declaringClass;

Methods Summary
public boolean	equals(java.lang.Object obj) Overrides MappingElementImpl's equals method to add comparison of the name of the declaring class this mapping element. The method returns false if obj does not have a declaring class with the same name as this mapping element. return true if this object is the same as the obj argument; false otherwise. param obj the reference object with which to compare. if (super.equals(obj) && (obj instanceof MappingMemberElement)) { MappingClassElement declaringClass = getDeclaringClass(); MappingClassElement objDeclaringClass = ((MappingMemberElement)obj).getDeclaringClass(); return ((declaringClass == null) ? (objDeclaringClass == null) : declaringClass.equals(objDeclaringClass)); } return false;
protected final void	firePropertyChange(java.lang.String name, java.lang.Object o, java.lang.Object n) Fires property change event. This method overrides that of MappingElementImpl to update the MappingClassElementImpl's modified status. param name property name param o old value param n new value // even though o == null and n == null will signify a change, that // is consistent with PropertyChangeSupport's behavior and is // necessary for this to work boolean noChange = ((o != null) && (n != null) && o.equals(n)); MappingClassElement classElement = getDeclaringClass(); super.firePropertyChange(name, o, n); if ((classElement != null) && !noChange) classElement.setModified(true);
protected final void	fireVetoableChange(java.lang.String name, java.lang.Object o, java.lang.Object n) Fires vetoable change event. This method overrides that of MappingElementImpl to give listeners a chance to block changes on the mapping class element modified status. param name property name param o old value param n new value exception PropertyVetoException when the change is vetoed by a listener // even though o == null and n == null will signify a change, that // is consistent with PropertyChangeSupport's behavior and is // necessary for this to work boolean noChange = ((o != null) && (n != null) && o.equals(n)); MappingClassElement classElement = getDeclaringClass(); super.fireVetoableChange(name, o, n); if ((classElement != null) && !noChange) { ((MappingClassElementImpl)classElement).fireVetoableChange( PROP_MODIFIED, Boolean.FALSE, Boolean.TRUE); }
public MappingClassElement	getDeclaringClass() Get the declaring class. return the class that owns this member element, or null if the element is not attached to any class return _declaringClass;
public int	hashCode() Overrides MappingElementImpl's hashCode method to add the hashCode of this mapping element's declaring class. return a hash code value for this object. MappingClassElement declaringClass = getDeclaringClass(); return (super.hashCode() + ((declaringClass == null) ? 0 : declaringClass.hashCode()));
public void	setDeclaringClass(MappingClassElement declaringClass) Set the declaring class of this mapping member. This method should only be used internally and for cloning and archiving. param declaringClass the declaring class of this mapping member _declaringClass = declaringClass;
