public interface PropagationConstraint
extends Property

Defines the propagation behavior for a relation when context-related events (add, remove, delete) occur on the source entity or the relation itself.

The default propagation constraints are:

• IsRelatedTo: delete=keep, remove=keep, add=unpropagate
• ConsistsOf: delete=cascade, remove=cascade, add=propagate

For more details, refer to the gCube Facet Based Resource Model Wiki.

Method Details

getAddConstraint

@ISProperty(name="add",
            description="It indicates the behaviour to implement for the target Entity when an \'add\' action is performed on the source Resource. Add action is the operation of adding an instance to a context.",
            mandatory=true,
            nullable=false)
PropagationConstraint.AddConstraint getAddConstraint()

Returns the propagation constraint for the 'add' operation.

Returns:

Parameters:

addConstraint - The PropagationConstraint.AddConstraint to set.

getDeleteConstraint

@ISProperty(name="delete",
            description="It indicates the behaviour to implement for the target Entity when a \'delete\' action is performed on the source Resource. Delet action  is the operation of deleting an instance (it has an impact on all contexts).",
            mandatory=true,
            nullable=false)
PropagationConstraint.DeleteConstraint getDeleteConstraint()

Returns the propagation constraint for the 'delete' operation.

Returns:

setDeleteConstraint

void setDeleteConstraint(PropagationConstraint.DeleteConstraint deleteConstraint)

Sets the propagation constraint for the 'delete' operation.

Parameters:

deleteConstraint - The PropagationConstraint.DeleteConstraint to set.

getRemoveConstraint

@ISProperty(name="remove",
            description="It indicates the behaviour to implement for the target Entity when a \'remove\' action is performed on the source Resource. Remove actions is the operation of removing an instance from a context.",

The PropagationConstraint.RemoveConstraint.

setRemoveConstraint

void setRemoveConstraint(PropagationConstraint.RemoveConstraint removeConstraint)

Sets the propagation constraint for the 'remove' operation.

Parameters:

removeConstraint - The PropagationConstraint.RemoveConstraint to set.
