FeatureEvent

BatchFeatureEvent

All Implemented Interfaces:

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.

BatchFeatureEvent

BatchFeatureEvent

public BatchFeatureEvent(FeatureSource<? extends FeatureType,? extends Feature> featureSource,
                         ReferencedEnvelope bounds,
                         Filter filter)

Method Detail

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(String tempFid,
                       String actualFid)

Used to update any FeatureId during a commit.

getCreatedFeatureIds

public WeakHashSet<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
