PostgisFeatureLocking

public class PostgisFeatureLocking extends PostgisFeatureStore implements FeatureLocking(Code)

Extends PostgisFeatureLocking with support for Locking.

This class will be, horror, modey. While the are plenty of Object Oriented ways to fix this I have a deadline right now.

When the DataStore is constructed it will create a LockingManager only if the Postgis implementation does not support database locking. If the lockingManger is present it will be used.

If the lockingManger is not present, the this class will use Database locking

public PostgisFeatureLocking(PostgisDataStore postgisDataStore, FeatureType featureType) throws IOException(Code)

Method Detail

lockFeature
public int lockFeature(Feature feature) throws IOException(Code)
	HACK HACK HACK!!! Don't use unless you're working on geoserver. just using ints for return now, to easily swap out with what we've got going on right now. Parameters: feature - DOCUMENT ME! DOCUMENT ME! throws: IOException - DOCUMENT ME! throws: UnsupportedOperationException - DOCUMENT ME!

lockFeatures
public int lockFeatures() throws IOException(Code)
	Lock all Features Number of Locked features throws: IOException - See Also: org.geotools.data.FeatureLocking.lockFeatures

lockFeatures
public int lockFeatures(Filter filter) throws IOException(Code)
	Lock features matching `filter`. Parameters: filter - Number of locked Features throws: IOException - See Also: org.geotools.data.FeatureLocking.lockFeatures(org.geotools.filter.Filter)

lockFeatures
public int lockFeatures(org.geotools.filter.Filter filter) throws IOException(Code)

lockFeatures
public int lockFeatures(Query query) throws IOException(Code)
	Lock features matching Query. FeatureStores that have provided their own locking to will need to override this method. Parameters: query - Number of locked Features throws: IOException - If we could not determine which feature to lockbased on Query throws: UnsupportedOperationException - When DataStore does not provide aLockingManager throws: DataSourceException - If feature to be locked does not exist See Also: org.geotools.data.FeatureLocking.lockFeatures(org.geotools.data.Query)

setFeatureLock
public void setFeatureLock(FeatureLock lock)(Code)
	Provide a FeatureLock for locking opperations to opperate against. Initial Transactional duration locks can be restored with setFeatureLock( FetaureLock.TRANSACTION ) Parameters: lock - FeatureLock (or FeatureLock.TRANSACTION ); throws: NullPointerException - If lock was `null` See Also: org.geotools.data.FeatureLocking.setFeatureLock(org.geotools.data.FeatureLock)

unLockFeatures
public void unLockFeatures() throws IOException(Code)
	Unlock all Features. throws: IOException - See Also: org.geotools.data.FeatureLocking.unLockFeatures

unLockFeatures
public void unLockFeatures(Filter filter) throws IOException(Code)
	Unlock Features specified by `filter`. Parameters: filter - throws: IOException - See Also: org.geotools.data.FeatureLocking.unLockFeatures(org.geotools.filter.Filter)

unLockFeatures
public void unLockFeatures(Query query) throws IOException(Code)
	Unlock features specified by the `query`. FeatureStores that have provided their own locking to will need to override this method. Parameters: query - throws: IOException - throws: UnsupportedOperationException - If lockingManager is not providedby DataStore subclass throws: DataSourceException - Filter describes an unlocked Feature, orauthorization not held See Also: org.geotools.data.FeatureLocking.unLockFeatures(org.geotools.data.Query)
