org.geotools.data.jdbc .JDBCFeatureWriter

All known Subclasses:   org.geotools.data.jdbc .JDBCTextFeatureWriter,  org.geotools.data.jdbc .JDBCPSFeatureWriter,
JDBCFeatureWriter
public class JDBCFeatureWriter implements FeatureWriter(Code)
JDBCDataStore implementation of the FeatureWriter interface
author:
   aaime

Field Summary
protected boolean closed

protected Feature current

protected Object[] fidAttributes

protected Feature live

protected QueryData queryData

protected FeatureReader reader


Constructor Summary
public JDBCFeatureWriter(FeatureReader reader, QueryData queryData)


Method Summary
public void close()

protected void doInsert(MutableFIDFeature mutable)
     Inserts a feature into the database.
This method should both insert a Feature, and update its FID in case the FIDMapper works over database generated ids like autoincrement fields, sequences, and object ids.

Postgis needs to do this seperately.
protected void doUpdate(Feature live, Feature current)

public FeatureType getFeatureType()

public boolean hasNext()

public Feature next()

public void remove()

protected boolean useQueryDataForInsert()

public void write()


Field Detail
closed
protected boolean closed(Code)

current
protected Feature current(Code)

fidAttributes
protected Object[] fidAttributes(Code)

live
protected Feature live(Code)

queryData
protected QueryData queryData(Code)

reader
protected FeatureReader reader(Code)

Constructor Detail
JDBCFeatureWriter
public JDBCFeatureWriter(FeatureReader reader, QueryData queryData)(Code)

Method Detail
close
public void close() throws IOException(Code)

See Also:   org.geotools.data.FeatureWriter.close

doInsert
protected void doInsert(MutableFIDFeature mutable) throws IOException, SQLException(Code)
Inserts a feature into the database.
This method should both insert a Feature, and update its FID in case the FIDMapper works over database generated ids like autoincrement fields, sequences, and object ids.

Postgis needs to do this seperately. With updates it can just override the geometry stuff, using a direct sql update statement, but for inserts it can't update a row that doesn't exist yet.

Parameters:
  mutable -
throws:
  IOException -
throws:
  SQLException -

doUpdate
protected void doUpdate(Feature live, Feature current) throws IOException, SQLException(Code)

getFeatureType
public FeatureType getFeatureType()(Code)

See Also:   org.geotools.data.FeatureWriter.getFeatureType

hasNext
public boolean hasNext() throws IOException(Code)

See Also:   org.geotools.data.FeatureWriter.hasNext

next
public Feature next() throws IOException(Code)

See Also:   org.geotools.data.FeatureWriter.next

remove
public void remove() throws IOException(Code)

See Also:   org.geotools.data.FeatureWriter.remove

useQueryDataForInsert
protected boolean useQueryDataForInsert()(Code)
Returns true if QueryData is used to insert rows, false if some other means is used

write
public void write() throws IOException(Code)

See Also:   org.geotools.data.FeatureWriter.write
