Method Detail

getRole1

public Role getRole1()

Specified by:

getRole1 in interface Association

getRole2

public Role getRole2()

Specified by:

getRole2 in interface Association

getPlayer1

public DeepaMehtaObject getPlayer1()

Specified by:

getPlayer1 in interface Association

getPlayer2

public DeepaMehtaObject getPlayer2()

Specified by:

getPlayer2 in interface Association

getRole

public Role getRole(String roleTypeUri)

Specified by:

getRole in interface Association

Returns:

this association's role that matches the given role type. If no role matches, null is returned. If both roles are matching an exception is thrown.

hasSameRoleTypeUris

public boolean hasSameRoleTypeUris()

Specified by:

hasSameRoleTypeUris in interface Association

matches

public boolean matches(String roleTypeUri1,
                       long playerId1,
                       String roleTypeUri2,
                       long playerId2)

Description copied from interface: Association

Checks if the given players match this association. The given role type URIs must be different. The player position ("1" vs. "2") is not relevant.

Specified by:

matches in interface Association

Returns:

true if the given players match this association.

getOtherPlayerId

public long getOtherPlayerId(long id)

Specified by:

getOtherPlayerId in interface Association

getTopic

public Topic getTopic(String roleTypeUri)

Description copied from interface: Association

### TODO: make it work for assoc players as well or drop it

Specified by:

getTopic in interface Association

getTopicByType

public Topic getTopicByType(String topicTypeUri)

Description copied from interface: Association

### TODO: make it work for assoc players as well or drop it

Specified by:

getTopicByType in interface Association

getRole

public Role getRole(RoleModel roleModel)

Description copied from interface: Association

### TODO: rethink this method Returns this association's role which refers to the same object as the given role model. The role returned is found by comparing topic IDs, topic URIs, or association IDs. The role types are not compared.

If the object refered by the given role model is not a player in this association an exception is thrown.

Specified by:
