PostgisFeatureWriter
public class PostgisFeatureWriter extends JDBCTextFeatureWriter (Code)
An implementation of FeatureWriter that will work over a result set.


Field Summary
protected static  WKTWritergeometryWriter
     Well Known Text writer (from JTS).

Constructor Summary
public  PostgisFeatureWriter(FeatureReader fReader, QueryData queryData, boolean WKBEnabled, boolean byteaWKB, PostgisSQLBuilder sqlBuilder)
    
Parameters:
  fReader -
Parameters:
  queryData -
Parameters:
  WKBEnabled -
Parameters:
  byteaWKB - -- true if you're using postgis 1.0+.

Method Summary
protected  StringencodeColumnName(String colName)
    
protected  StringencodeName(String tableName)
     DJB: this is the javadoc from the superclass, but this wasnt being done.
protected  StringgetGeometryInsertText(Geometry geom, int srid)
    
public  booleanisWKBEnabled()
    
protected  StringmakeSelectForUpdateSql(Feature current)
     For postgres >= 8.1 NOWAIT is used (meaning you get a response).

Field Detail
geometryWriter
protected static WKTWriter geometryWriter(Code)
Well Known Text writer (from JTS).




Constructor Detail
PostgisFeatureWriter
public PostgisFeatureWriter(FeatureReader fReader, QueryData queryData, boolean WKBEnabled, boolean byteaWKB, PostgisSQLBuilder sqlBuilder) throws IOException(Code)

Parameters:
  fReader -
Parameters:
  queryData -
Parameters:
  WKBEnabled -
Parameters:
  byteaWKB - -- true if you're using postgis 1.0+. they changed how to do wkb writing.
throws:
  IOException -




Method Detail
encodeColumnName
protected String encodeColumnName(String colName)(Code)



encodeName
protected String encodeName(String tableName)(Code)
DJB: this is the javadoc from the superclass, but this wasnt being done. Encodes the tableName, default is to do nothing, but postgis will override and put double quotes around the tablename.



getGeometryInsertText
protected String getGeometryInsertText(Geometry geom, int srid) throws IOException(Code)



isWKBEnabled
public boolean isWKBEnabled()(Code)
Returns true if the WKB format is used to transfer geometries, false otherwise



makeSelectForUpdateSql
protected String makeSelectForUpdateSql(Feature current)(Code)
For postgres >= 8.1 NOWAIT is used (meaning you get a response). Prior versions will block during concurrent editing.



setWKBEnabled
public void setWKBEnabled(boolean enabled)(Code)
If turned on, WKB will be used to transfer geometry data instead of WKT
Parameters:
  enabled -
