Constructor Detail

ReadOnlyTopicMap

public ReadOnlyTopicMap()

Method Detail

getBaseAddress

public LocatorIF getBaseAddress()

setBaseAddress

public void setBaseAddress(LocatorIF baseAddress)

getTitle

public java.lang.String getTitle()

setTitle

public void setTitle(java.lang.String title)

_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.

getTopicMap

public TopicMapIF getTopicMap()

Description copied from interface: TMObjectIF

PUBLIC: Gets the topic map that this object belongs to. If the object has been removed from its topic map or not added to a topic map yet this will be null.

Specified by:

getTopicMap in interface TMObjectIF

Overrides:

getTopicMap in class ReadOnlyTMObject

Returns:

A topic map; an object implementing TopicMapIF.

getStore

public TopicMapStoreIF getStore()

Description copied from interface: TopicMapIF

PUBLIC: Gets the store to which the topic map's transaction is connected.

Specified by:

getStore in interface TopicMapIF

getTransaction

public TopicMapTransactionIF getTransaction()

getBuilder

public TopicMapBuilderIF getBuilder()

Description copied from interface: TopicMapIF

PUBLIC: Gets a topic map builder for use with this transaction.

Specified by:

getBuilder in interface TopicMapIF

Returns:

An object implementing TopicMapBuilderIF

getIndex

public java.lang.Object getIndex(java.lang.String name)

Description copied from interface: TopicMapIF

PUBLIC: Gets an index by name. An index is usually named by the IndexIF subinterface that it implements. All indexes are kept up-to-date at all times.

Specified by:

getIndex in interface TopicMapIF

Parameters:

name - A string; the index name, i.e.g the interface that it implements.

Returns:

An instance implementing the index interface.

setTransaction

Returns:

A collection of AssociationIF objects.

getObjectById

public TMObjectIF getObjectById(java.lang.String object_id)

Description copied from interface: TopicMapIF

PUBLIC: Gets the topic map object that has the given object id, from this topic map. If there is no object with that object id in this topic map, then null is returned.

Specified by:
