java.lang.Enum<RelationProperty.ReferentiaIntegrity>

org.gcube.informationsystem.model.embedded.RelationProperty.ReferentiaIntegrity

All Implemented Interfaces:

Serializable, Comparable<RelationProperty.ReferentiaIntegrity>

Enclosing interface:

RelationProperty

public static enum RelationProperty.ReferentiaIntegrity
extends Enum<RelationProperty.ReferentiaIntegrity>

Author:

Luca Frosini (ISTI - CNR) http://www.lucafrosini.com/ The referential integrity value have their meaning taking in account the Edge direction. So that is the action to be made when an action occurs on source Vertex.

Enum Constant Detail

onDeleteCascadeWhenOrphan

public static final RelationProperty.ReferentiaIntegrity onDeleteCascadeWhenOrphan

When the source Vertex is deleted also the target Vertex is deleted if there are no other incoming edge.

onDeleteCascade

public static final RelationProperty.ReferentiaIntegrity onDeleteCascade

When the source Vertex is deleted also the target Vertex is always deleted

onDeleteKeep

public static final RelationProperty.ReferentiaIntegrity onDeleteKeep

When the source Vertex is deleted also the target Vertex is keep. This is the standard behavior also if no integrity is declared.

Method Detail

values

public static RelationProperty.ReferentiaIntegrity[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (RelationProperty.ReferentiaIntegrity c : RelationProperty.ReferentiaIntegrity.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static RelationProperty.ReferentiaIntegrity valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
