Class BatchFeatureEvent
java.lang.Object
java.util.EventObject
org.geotools.data.FeatureEvent
org.geotools.data.BatchFeatureEvent
- All Implemented Interfaces:
- java.io.Serializable
public class BatchFeatureEvent
- extends FeatureEvent
Provide batch notification on Commit / Rollback.
This is used by FeatureListenerManager to report a bit more detail
on transaction commit() and rollback(). Previously these changes
were represented as an change event with no known bounds.

public BatchFeatureEvent(FeatureSource<? extends org.opengis.feature.type.FeatureType,? extends org.opengis.feature.Feature> featureSource,
ReferencedEnvelope bounds,
org.opengis.filter.Filter filter)
setType
public void setType(FeatureEvent.Type type)
- Used to change this into a COMMIT or ROLLBACK if needed.
- Parameters:
type
-
add
public void add(FeatureEvent change)
- Indicate a change being batched.
Will be use to update internal state of bounds and filter; in
the special case of Features being added we will record
the FeatureIds in case we need to update them later (this
is only required for a *commit* event).
replaceFid
public void replaceFid(java.lang.String tempFid,
java.lang.String actualFid)
- Used to update any FeatureId during a commit.
getCreatedFeatureIds
public WeakHashSet<org.opengis.filter.identity.Identifier> getCreatedFeatureIds()
- This is the set of Identifiers that have been created
over the course of this operation.
Please note that this is only the set of identifiers that is *still in use*;
if no client code is holding on to these Identifiers waiting to see what
the final value will be we are not going to hold onto these for you.
- Returns:
- Set of Identifiers created during this commit
