TODO:
REVISIT: Make modify/add/remove atomic if the transaction is AUTO_COMMIT. This is done by the start of each of those method checking to see if the transaction is auto-commit, if it is then they make a new transaction and pass that to the writer. The writer does its thing, and then at the end of the method you just commit the transaction. This way if the writer messes up its changes are rolled back. The old jdbc datasources supported this, and it'd be nice to do here as well., UPDATE: made modify atomic as an example, I actually have the beginings of a smart idea in mind. Similar to SwingUtilities.runLater...

Field Detail

transaction

protected Transaction transaction
Deprecated. 
Current Transaction this FeatureSource is opperating against

Constructor Detail

JDBCFeatureStore

public JDBCFeatureStore(JDBC1DataStore jdbcDataStore,
                        SimpleFeatureType featureType)
Deprecated. 
Method Detail

getTransaction

public Transaction getTransaction()
Deprecated. 
Description copied from class: JDBCFeatureSource
Retrieve the Transaction this FeatureSource is opperating against.

For a plain JDBCFeatureSource that cannot modify this will always be Transaction.AUTO_COMMIT.

Specified by:
getTransaction in interface FeatureStore<SimpleFeatureType,SimpleFeature>
Overrides:
getTransaction in class JDBCFeatureSource
Returns:
DOCUMENT ME!

getInProcessLockingManager

protected InProcessLockingManager getInProcessLockingManager()
Deprecated. 
Used by subclasses to access locking manager.

All our implementations here are rely on FeatureWriter to check the locks.

When making your own SQL opperations, have a look at assertFids( Set fids ), and assertFids( Filter ). You may use these to check against the lockingManager if one is used.

If the lockingManager is not used, ie is null, it assumed that you are making use of native database locks. Or doing your own thing.

That is the assertFids functions only when lockingManager is non null.

Returns:
LockingManager

fids

protected Set fids(Filter filter)
            throws NoSuchElementException,
                   IOException,
                   IllegalAttributeException
Deprecated. 
Throws:
NoSuchElementException
IOException
IllegalAttributeException

assertFilter

protected void assertFilter(Filter filter)
                     throws IOException
Deprecated. 
Throws:
IOException

assertFids

protected void assertFids(Set fids)
                   throws FeatureLockException
Deprecated. 
Throws:
FeatureLockException

modifyFeatures

public void modifyFeatures(AttributeDescriptor type,
                           Object value,
                           Filter filter)
                    throws IOException
Deprecated. 
Modifies features matching filter.

Equivelent to:


 modifyFeatures( new AttributeDescriptor[]{ type, }, new Object[]{ value, }, filter );
 
 

Subclasses may override this method to perform the appropriate optimization for this result.

Specified by:
modifyFeatures in interface FeatureStore<SimpleFeatureType,SimpleFeature>
Parameters:
type - Attribute to modify
value - Modification being made to type
filter - Identifies features to modify
Throws:
IOException

modifyFeatures

public void modifyFeatures(AttributeDescriptor[] type,
                           Object[] value,
                           Filter filter)
                    throws IOException
Deprecated. 
Modifies features matching filter.

Equivelent to:


 FeatureWriter writer = dataStore.getFeatureWriter( typeName, filter, transaction );
 Feature feature;
 while( writer.hasNext() ){
    feature = writer.next();
    feature.setAttribute( type[0].getName(), value[0] );
    feature.setAttribute( type[1].getName(), value[1] );
    ...
    feature.setAttribute( type[N].getName(), value[N] ); 
    writer.write();
 }
 writer.close();

                       throws DataSourceException,
                              IOException
Deprecated.

IOException

addFeatures

public Set addFeatures(FeatureReader<SimpleFeatureType,SimpleFeature> reader)
                throws IOException
Deprecated.

 Set set = new HashSet();
 FeatureWriter writer = dataStore.getFeatureWriter( typeName, true, transaction );
 Featrue feature, newFeature;
 while( reader.hasNext() ){
    feature = reader.next();
    newFeature = writer.next();
    newFeature.setAttributes( feature.getAttribtues( null ) );
    writer.write();
    set.add( newfeature.getID() );

setTransaction

public void setTransaction(Transaction transaction)
Deprecated. 
Description copied from interface: FeatureStore
Provides a transaction for commit/rollback control of this FeatureStore.

This method operates as a replacement for setAutoCommitMode. When a transaction is provided you are no longer automatically committing.

In order to return to AutoCommit mode supply the Transaction.AUTO_COMMIT to this method. Since this represents a return to AutoCommit mode the previous Transaction will be commited.

Specified by:
setTransaction in interface FeatureStore<SimpleFeatureType,SimpleFeature>
Parameters:
transaction - DOCUMENT ME!
