Constructor Details

PersistenceFieldElementImpl

public PersistenceFieldElementImpl()

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

PersistenceFieldElementImpl

public PersistenceFieldElementImpl(String name)

Creates new PersistenceFieldElementImpl with the corresponding name

Parameters:

name - the name of the element

Method Details

getPersistenceType

public int getPersistenceType()

Get the persistence type of this field element.

Specified by:

getPersistenceType in interface PersistenceFieldElement.Impl

Returns:

the persistence type, one of PersistenceFieldElement.PERSISTENT or PersistenceFieldElement.DERIVED. The default is PERSISTENT.

setPersistenceType

public void setPersistenceType(int type)
                        throws ModelException

Set the persistence type of this field element.

Specified by:

setPersistenceType in interface PersistenceFieldElement.Impl

Parameters:

type - - an integer indicating the persistence type, one of: PersistenceFieldElement.PERSISTENT or PersistenceFieldElement.DERIVED

Throws:

ModelException - if impossible

isReadSensitive

public boolean isReadSensitive()

Determines whether this field element is read sensitive or not. This value is only used if getPersistenceType returns DERIVED

Specified by:

isReadSensitive in interface PersistenceFieldElement.Impl

Returns:

true if the field is read sensitive, false if it is not or if the persistence type is not derived

See Also:

• isWriteSensitive()
• setPersistenceType(int)
• PersistenceFieldElement.DERIVED

setReadSensitive

public void setReadSensitive(boolean flag)
                      throws ModelException

Set whether this field element is read sensitive or not.

Specified by:

setReadSensitive in interface PersistenceFieldElement.Impl

Parameters:

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

Throws:

ModelException - if impossible

See Also:

• setWriteSensitive(boolean)
• setPersistenceType(int)
• PersistenceFieldElement.DERIVED

isWriteSensitive

public boolean isWriteSensitive()

Determines whether this field element is write sensitive or not. This value is only used if getPersistenceType returns DERIVED

Specified by:

isWriteSensitive in interface PersistenceFieldElement.Impl

Returns:

true if the field is write sensitive, false if it is not or if the persistence type is not derived

See Also:

• isReadSensitive()
• setPersistenceType(int)
• PersistenceFieldElement.DERIVED

setWriteSensitive

public void setWriteSensitive(boolean flag)
                       throws ModelException

Set whether this field element is write sensitive or not.

Specified by:

setWriteSensitive in interface PersistenceFieldElement.Impl

Parameters:

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

Throws:

ModelException - if impossible

See Also:

• setReadSensitive(boolean)
• setPersistenceType(int)
