Interface ILinkSet

All Superinterfaces:

Collection<IGPO>, Iterable<IGPO>, Set<IGPO>

All Known Subinterfaces:

IOrderedLinkSet

All Known Implementing Classes:

LinkSet

public interface ILinkSet
extends Set<IGPO>

A collection of links into (edges in) or links out of (edges out) of an IGPO.

Note that the links out are only intended to be used to represent many-many associations. Standard one-many associations should be represented by linksIn (many links pointing to one resource rather than many links from one resource pointing to many other resources).

The LinksOut as the low-cardinality part of a many-many association reflect common asymmetry of such associations. Experience suggests that if the association is more symmetric the cardinalities tend not to be large.

Methods

Modifier and Type	Method and Description
boolean	equals(Object o) Returns true iff o is the same link set (same link property and same container).
org.openrdf.model.URI	getLinkProperty() The name of the property that the members of the link set use to point to the generic object that is collecting this link set.
IGPO	getOwner() The generic object that is being pointed at by the members of the link set.
boolean	isLinkSetIn() true iff this link set models the links into the owner (edges in) and false iff this link set models the links out of the owner (edges out).
<C> Iterator<C>	iterator(Class<C> theClassOrInterface) Returns an Iterator that will visit objects that are instances of the specificed class or interface (the backing IGPO objects are wrapped by a suitable IGenericSkin).
int	size() The #of members in the link set.

Method Detail

equals

boolean equals(Object o)

Returns true iff o is the same link set (same link property and same container).

Specified by:

equals in interface Collection<IGPO>

Specified by:

equals in interface Set<IGPO>

Overrides:

equals in class Object

getLinkProperty(), getOwner()

getOwner

IGPO getOwner()

The generic object that is being pointed at by the members of the link set.

getLinkProperty

org.openrdf.model.URI getLinkProperty()

The name of the property that the members of the link set use to point to the generic object that is collecting this link set.

isLinkSetIn

boolean isLinkSetIn()

true iff this link set models the links into the owner (edges in) and false iff this link set models the links out of the owner (edges out).

size

int size()

The #of members in the link set.

Specified by:

size in interface Collection<IGPO>

size in interface Set<IGPO>

sizeLong

iterator

<C> Iterator<C> iterator(Class<C> theClassOrInterface)

Returns an Iterator that will visit objects that are instances of the specificed class or interface (the backing IGPO objects are wrapped by a suitable IGenericSkin).

Throws:

UnsupportedOperationException - if theClassOrInterface is not a registered IGenericSkin.
