Constructor Detail

ReadOnlyAssociation

public ReadOnlyAssociation()

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.

getRoleTypes

public java.util.Collection<TopicIF> getRoleTypes()

Description copied from interface: AssociationIF

PUBLIC: Gets a Collection of association role types found in this association. The returned collection does not contain any duplicates. Even if some roles have no type, null will not be returned as one of the role types in the returned set.

Specified by:

getRoleTypes in interface AssociationIF

Returns:

A Collection of TopicIF objects.

getRolesByType

public java.util.Collection<AssociationRoleIF> getRolesByType(TopicIF roletype)

Description copied from interface: AssociationIF

PUBLIC: Gets the association roles in this association which are of the given role type.

Specified by:

getRolesByType in interface AssociationIF

Parameters:

roletype - The type of the roles returned; an object implementing TopicIF. If null the method will return the roles that have no type.

Returns:

A Collection of AssociationRoleIF objects.

getRoles

public java.util.Collection<AssociationRoleIF> getRoles()

Description copied from interface: AssociationIF

PUBLIC: Gets all the association roles of the association. The returned roles may appear in any order.

Specified by:

getRoles in interface AssociationIF

Returns:

A collection of AssociationRoleIF objects.

getScope

public java.util.Collection<TopicIF> getScope()

Description copied from interface: ScopedIF

PUBLIC: Returns the set of topics that are the stated scope of this object. Scoping topics inherited from parent objects are not included. There is no guarantee as to which order these topics are returned in.

Specified by:

getScope in interface ScopedIF

Returns:

A collection of TopicIF objects.

addTheme

public void addTheme(TopicIF theme)

Parameters:

theme - A topic to be added to this scope; an object implementing TopicIF.

removeTheme

public void removeTheme(TopicIF theme)

Description copied from interface: ScopedIF

Specified by:

removeTheme in interface ScopedIF

Parameters:

theme - A topic to be removed from this scope; an object implementing TopicIF.

getType
