PersistenceFieldElementImpl

• java.lang.Object
  • PersistenceMemberElementImpl

Fields Summary
private static final int	READ_SENSITIVE Constant representing read sensitive.
private static final int	WRITE_SENSITIVE Constant representing write sensitive.
private int	_persistenceType Persistence type of the field element.
private int	_derivedModifier Derived modifier of the field element.
private boolean	_isKey Key field flag of the field element.

Constructors Summary
public PersistenceFieldElementImpl() Create new PersistenceFieldElementImpl with no corresponding name. This constructor should only be used for cloning and archiving. this(null);
public PersistenceFieldElementImpl(String name) Creates new PersistenceFieldElementImpl with the corresponding name param name the name of the element super(name); _persistenceType = PersistenceFieldElement.PERSISTENT;

Methods Summary
public int	getPersistenceType() Get the persistence type of this field element. return the persistence type, one of {@link PersistenceFieldElement#PERSISTENT} or {@link PersistenceFieldElement#DERIVED}. The default is PERSISTENT. return _persistenceType;
public boolean	isKey() Determines whether this field element is a key field or not. return true if the field is a key field, false otherwise see PersistenceClassElement#getKeyClass return _isKey;
public boolean	isReadSensitive() Determines whether this field element is read sensitive or not. This value is only used if getPersistenceType returns DERIVED return true if the field is read sensitive, false if it is not or if the persistence type is not derived see #isWriteSensitive see #setPersistenceType see PersistenceFieldElement#DERIVED return ((PersistenceFieldElement.DERIVED == getPersistenceType()) ? ((_derivedModifier & READ_SENSITIVE) != 0) : false);
public boolean	isWriteSensitive() Determines whether this field element is write sensitive or not. This value is only used if getPersistenceType returns DERIVED return true if the field is write sensitive, false if it is not or if the persistence type is not derived see #isReadSensitive see #setPersistenceType see PersistenceFieldElement#DERIVED return ((PersistenceFieldElement.DERIVED == getPersistenceType()) ? ((_derivedModifier & WRITE_SENSITIVE) != 0) : false);
public void	setKey(boolean flag) Set whether this field element is a key field or not. param flag - if true, the field element is marked as a key field; otherwise, it is not exception ModelException if impossible see PersistenceClassElement#getKeyClass Boolean old = JavaTypeHelper.valueOf(isKey()); Boolean newFlag = JavaTypeHelper.valueOf(flag); try { fireVetoableChange(PROP_KEY_FIELD, old, newFlag); _isKey = flag; firePropertyChange(PROP_KEY_FIELD, old, newFlag); } catch (PropertyVetoException e) { throw new ModelVetoException(e); }
public void	setPersistenceType(int type) Set the persistence type of this field element. param type - an integer indicating the persistence type, one of: {@link PersistenceFieldElement#PERSISTENT} or {@link PersistenceFieldElement#DERIVED} exception ModelException if impossible Integer old = new Integer(getPersistenceType()); Integer newType = new Integer(type); try { fireVetoableChange(PROP_PERSISTENCE, old, newType); _persistenceType = type; firePropertyChange(PROP_PERSISTENCE, old, newType); } catch (PropertyVetoException e) { throw new ModelVetoException(e); }
public void	setReadSensitive(boolean flag) Set whether this field element is read sensitive or not. param flag - if true and this is a derived field, the field element is marked as read sensitive; otherwise, it is not This value is only used if getPersistenceType returns DERIVED exception ModelException if impossible see #setWriteSensitive see #setPersistenceType see PersistenceFieldElement#DERIVED Boolean old = JavaTypeHelper.valueOf(isReadSensitive()); Boolean newFlag = JavaTypeHelper.valueOf(flag); try { fireVetoableChange(PROP_SENSITIVITY, old, newFlag); if (flag) _derivedModifier |= READ_SENSITIVE; else _derivedModifier &= READ_SENSITIVE; firePropertyChange(PROP_SENSITIVITY, old, newFlag); } catch (PropertyVetoException e) { throw new ModelVetoException(e); }
public void	setWriteSensitive(boolean flag) Set whether this field element is write sensitive or not. param flag - if true and this is a derived field, the field element is marked as write sensitive; otherwise, it is not This value is only used if getPersistenceType returns DERIVED exception ModelException if impossible see #setReadSensitive see #setPersistenceType see PersistenceFieldElement#DERIVED Boolean old = JavaTypeHelper.valueOf(isWriteSensitive()); Boolean newFlag = JavaTypeHelper.valueOf(flag); try { fireVetoableChange(PROP_SENSITIVITY, old, newFlag); if (flag) _derivedModifier |= WRITE_SENSITIVE; else _derivedModifier &= WRITE_SENSITIVE; firePropertyChange(PROP_SENSITIVITY, old, newFlag); } catch (PropertyVetoException e) { throw new ModelVetoException(e); }
