Method Detail

getPersistenceType

int getPersistenceType()

Get the persistence type of this field element.

Returns:

the persistence type, one of PersistenceFieldElement.PERSISTENT or PersistenceFieldElement.DERIVED

setPersistenceType

void setPersistenceType(int type)
                 throws ModelException

Set the persistence type of this field element.

Parameters:

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

Throws:

ModelException - if impossible

isReadSensitive

boolean isReadSensitive()

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

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

void setReadSensitive(boolean flag)
               throws ModelException

Set whether this field element is read sensitive or not.

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

boolean isWriteSensitive()

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

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

void setWriteSensitive(boolean flag)
                throws ModelException

Set whether this field element is write sensitive or not.

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), PersistenceFieldElement.DERIVED

isKey

boolean isKey()

Determines whether this field element is a key field or not.

Returns:

true if the field is a key field, false otherwise

See Also:

PersistenceClassElement.getKeyClass()

setKey

void setKey(boolean flag)
     throws ModelException

Set whether this field element is a key field or not.

Parameters:

flag - - if true, the field element is marked as a key field; otherwise, it is not

Throws:

ModelException - if impossible
