Method Details

getTransaction

public Transaction getTransaction()

Description copied from interface: FeatureStore

Gets the Transaction that this FeatureStore is currently operating against.

 Transaction t = featureStore.getTransaction();
 try {
     featureStore.addFeatures( features );
     t.commit();
 } catch( IOException erp ){
     // something went wrong;
    java.util.logging.Logger.getGlobal().log(java.util.logging.Level.INFO, "", ex);
     t.rollback();
 }
 

Specified by:

getTransaction in interface FeatureStore<SimpleFeatureType,SimpleFeature>

Returns:

Transaction in use, or Transaction.AUTO_COMMIT

modifyFeatures

public void modifyFeatures(Name attributeName,
 Object attributeValue,
 Filter filter)
                    throws IOException

Description copied from interface: FeatureStore

Modifies an attribute with the supplied value in all features selected by the given filter.

Specified by:

modifyFeatures in interface FeatureStore<SimpleFeatureType,SimpleFeature>

Parameters:

attributeName - the attribute to modify

attributeValue - the new value for the attribute

filter - an OpenGIS filter

Throws:

IOException - if modification is not supported; if the value type does not match the attribute type; or if there errors accessing the data source

modifyFeatures

public void modifyFeatures(Name[] name,
 Object[] value,
 Filter filter)
                    throws IOException

Description copied from interface: FeatureStore

Modifies the attributes with the supplied values in all features selected by the given filter.

Specified by:

modifyFeatures in interface FeatureStore<SimpleFeatureType,SimpleFeature>

Parameters:

name - the attributes to modify

value - the new values for the attributes

filter - an OpenGIS filter

Throws:

IOException - if the attribute and object arrays are not equal in length; if the value types do not match the attribute types; if modification is not supported; or if there errors accessing the data source

 Object value,
 Filter filter)
                    throws IOException

Specified by:

modifyFeatures in interface SimpleFeatureStore

Throws:

removeFeatureListener

public void removeFeatureListener(FeatureListener listener)

Description copied from interface: FeatureSource

Removes an object from this FeatureSource's listeners.

Specified by:

removeFeatureListener in interface FeatureSource<SimpleFeatureType,SimpleFeature>

Overrides:

removeFeatureListener in class DirectoryFeatureSource

Parameters:
