Method Detail

open

public void open()

Description copied from interface: TopicMapReferenceIF

PUBLIC: Opens the reference.

Specified by:

open in interface TopicMapReferenceIF

Overrides:

open in class AbstractURLTopicMapReference

loadTopicMap

protected TopicMapIF loadTopicMap(boolean readonly)
                           throws IOException

Specified by:

loadTopicMap in class AbstractURLTopicMapReference

Throws:

IOException

getLastModifiedAt

protected long getLastModifiedAt(File file)

getLastModifiedAt

protected long getLastModifiedAt(URL url)

getAlwaysReindexOnLoad

public boolean getAlwaysReindexOnLoad()

setAlwaysReindexOnLoad

public void setAlwaysReindexOnLoad(boolean alwaysReindexOnLoad)

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

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 AutoCloseable

Specified by:

close in interface TopicMapReferenceIF

Overrides:

close in class AbstractURLTopicMapReference
