Constructor Details

ReadOnlyAssociationRole

public ReadOnlyAssociationRole()

Method Details

_p_getFieldCount

public int _p_getFieldCount()

Specified by:

_p_getFieldCount in interface PersistentIF

getClassIndicator

public String getClassIndicator()

Description copied from class: ReadOnlyTMObject

INTERNAL: Returns the token that can be used to indicate the class of this instance. This indicator is currently only used by item identifiers.

Specified by:

getClassIndicator in class ReadOnlyTMObject

getObjectId

public String getObjectId()

Description copied from interface: TMObjectIF

PUBLIC: Gets the id of this object. The object id is part of the topic map id space, and must be unique. The object id is not significant (or unique) outside the current topic map. The object id is immutable. The object id is thus stable through this object's lifetime.

Specified by:

getObjectId in interface TMObjectIF

Specified by:

getObjectId in class ReadOnlyTMObject

Returns:

string which is this object's id.

getAssociation

public AssociationIF getAssociation()

Description copied from interface: AssociationRoleIF

PUBLIC: Gets the association to which this association role belongs.

Specified by:

getAssociation in interface AssociationRoleIF

Returns:

The association to which this association role belongs; an object implementing AssociationIF.

getPlayer

public TopicIF getPlayer()

Description copied from interface: AssociationRoleIF

PUBLIC: Gets the topic that plays this association role (this member of the association).

Specified by:

getPlayer in interface AssociationRoleIF

Returns:

The topic (member) which plays this role in the association.

setPlayer

public void setPlayer(TopicIF player)

Description copied from interface: AssociationRoleIF

PUBLIC: Sets the topic that plays this association role. Note that this has the side-effect of removing the role from its current player, if any, and inserting it on the new player, if any.

Specified by:

setPlayer in interface AssociationRoleIF

Parameters:

player - The topic (member) which plays this role in the association. Can be null; if null, then the effect is that there is no player of this role in this association.

Description copied from interface: TypedIF

PUBLIC: Gets the type that this object is an instance of.

Specified by:

getType in interface TypedIF

Returns:

The type of this object; an object implementing TopicIF.

setType

public void setType(TopicIF type)

Description copied from interface: TypedIF

PUBLIC: Sets the type that this object is an instance of.

Specified by:

setType in interface TypedIF

Parameters:

type - The type for this object; an object implementing TopicIF.

getReifier

public TopicIF getReifier()

Description copied from interface: ReifiableIF

PUBLIC: Returns the topic that reifies this object.

Specified by:

getReifier in interface ReifiableIF

setReifier

public void setReifier(TopicIF reifier)
