Method Detail

reIndexAll

long reIndexAll(Context context)
Reindex everything.

Parameters:
context - used to report progress back to the user or to the logs. Must not be null.
Returns:
Reindex time in ms.

reIndexAllIssuesInBackground

long reIndexAllIssuesInBackground(Context context)
Reindex everything, but don't stop the world

Parameters:
context - used to report progress back to the user or to the logs. Must not be null.
Returns:
Reindex time in ms.
Since:
v5.2

optimize

long optimize()
Optimize the underlying indexes. Make the subsequent searching more efficient.

Returns:
the amount of time in millis this method took (because you are too lazy to time me), 0 if indexing is not enabled or -1 if we cannot obtain the index writeLock.
Throws:
IndexException - if the indexes are seriously in trouble

shutdown

void shutdown()
Shuts down the indexing manager and closes its resources (if any).

Specified by:
shutdown in interface Shutdown

activate

long activate(Context context)
Activates search indexes.

Parameters:
context - used to report progress back to the user or to the logs. Must not be null.
Returns:
Reindex time in ms

deactivate

void deactivate()
De-activates indexing (as happens from the admin page) and removes index directories.


isIndexingEnabled

boolean isIndexingEnabled()
Returns:
whether this index is enabled or true if all sub indexes are enabled

isIndexConsistent

boolean isIndexConsistent()
Returns:
the result of a simple consistency check that compares the index state to the current number of issues. A background re-index should not be attempted when this returns false.
Since:
5.2

getAllIndexPaths

Collection<String> getAllIndexPaths()
Returns:
a collection of Strings that map to all paths that contain Lucene indexes. Must not be null.

size

int size()
Specified by:
size in interface Sized
Returns:
how many Entities will be re-indexed by reIndexAll(Context)
