WFSFeatureWriter

public WFSFeatureWriter(WFSFeatureStore store,
                        WFSLocalTransactionState localSate,
                        FeatureReader<SimpleFeatureType,SimpleFeature> reader,

Method Detail

write

public void write()
           throws IOException

Description copied from class: DiffContentFeatureWriter

Writes out the current feature.

Specified by:

write in interface FeatureWriter<SimpleFeatureType,SimpleFeature>

Overrides:

write in class DiffContentFeatureWriter

Throws:

IOException

See Also:

FeatureWriter.write()

remove

public void remove()
            throws IOException

Description copied from interface: FeatureWriter

Removes current Feature, must be called before hasNext.

FeatureWriters will need to allow all FeatureSources of the same typeName to issue a FeatureEvent event of type FeatureEvent.FEATURES_REMOVED when this method is called.

If this FeatureWriter is opperating against a Transaction FEATURES_REMOVED events should only be sent to FeatureSources operating on the same Transaction. When Transaction commit() is called other FeatureSources will be informed of the modifications.

When the current Feature has been provided as new content, this method "cancels" the add opperation (and notification needed).

Specified by:

remove in interface FeatureWriter<SimpleFeatureType,SimpleFeature>

Overrides:

remove in class DiffContentFeatureWriter

Throws:

IOException

See Also:

FeatureWriter.remove()

hasNext

public boolean hasNext()
                throws IOException

Description copied from class: DiffContentFeatureWriter

Query for more content.

Specified by:

hasNext in interface FeatureWriter<SimpleFeatureType,SimpleFeature>

Overrides:

hasNext in class DiffContentFeatureWriter

Returns:

true if an additional Feature is available, false if not.

Throws:

IOException - if an I/O error occurs.

See Also:

FeatureWriter.hasNext()

next

public SimpleFeature next()
                   throws IOException

Description copied from class: DiffContentFeatureWriter

Next Feature from reader or new content.

Specified by:

next in interface FeatureWriter<SimpleFeatureType,SimpleFeature>

Overrides:

next in class DiffContentFeatureWriter

Returns:

Feature from Query, or newly appended Feature

Throws:

IOException - if the writer has been closed or an I/O error occurs reading the next Feature.

FeatureWriter.next()
