getSearcher

public SearcherIF getSearcher()

close

public void close()

Description copied from interface: TopicMapReferenceIF

PUBLIC: Closes all open stores and the reference itself. Note that topic map stores created through this reference are closed and dereferenced when the reference is closed. The reference can be reopened after it has been closed.

Specified by:

close in interface TopicMapReferenceIF

Overrides:

close in class AbstractURLTopicMapReference

delete

public void delete()

Description copied from class: AbstractURLTopicMapReference

INTERNAL: Deletes the topic map pointed to. The reference is closed before the topic map is deleted. Note that only URIs pointing to through files can actually be deleted, i.e. "file:" URLs.

Specified by:

delete in interface TopicMapReferenceIF

Overrides:

delete in class AbstractURLTopicMapReference

transactionCommit

public void transactionCommit(TopicMapTransactionIF transaction)

Specified by:

transactionCommit in interface TransactionEventListenerIF

transactionAbort

public void transactionAbort(TopicMapTransactionIF transaction)

Specified by:

transactionAbort in interface TransactionEventListenerIF

getImporter

protected abstract TopicMapImporterIF getImporter()
