Constructor Detail

ReadOnlyAssociationRole

public ReadOnlyAssociationRole()

Method Detail

_p_getFieldCount

public int _p_getFieldCount()

Specified by:

_p_getFieldCount in interface PersistentIF

getClassIndicator

public java.lang.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 java.lang.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.
