      org.geotools.filter.SQLEncoderOracle

SQLEncoderOracle
public class SQLEncoderOracle extends SQLEncoder (Code)
Encodes Geometry filters into valid oracle SDO statements.

At this stage it only supports the GEOMETRY_BBOX types.

Encoded filters get written to the protected Writer called out

Constructor Detail
SQLEncoderOracle
public SQLEncoderOracle(String fidColumn, int defaultSRID)(Code)



SQLEncoderOracle
public SQLEncoderOracle(int defaultSRID)(Code)



SQLEncoderOracle
public SQLEncoderOracle(String fidColumn, Map srids)(Code)
Creates a new SQLEncoderOracle with a specified SRID.
Parameters:
  fidColumn - DOCUMENT ME!
Parameters:
  srids - The Spatial Reference ID to use when generating SDO SQLstatements.



SQLEncoderOracle
public SQLEncoderOracle(Map srids)(Code)
Creates a new SQLEncoderOracle with a specified SRID.
Parameters:
  srids - The Spatial Reference ID to use when generating SDO SQLstatements.




Method Detail
createFilterCapabilities
protected FilterCapabilities createFilterCapabilities()(Code)
Sets the capabilities of this filter. FilterCapabilities for this Filter



toSDOGeom
public static String toSDOGeom(Geometry geometry, int srid)(Code)
Converts JTS Geometry to a String version of a SDO Geometry. This should move to a utility class, as we now have more than one class using this (which is why it changed to public static) TODO: Multi eometries
Parameters:
  geometry - The JTS Geometry to convert.
Parameters:
  srid - DOCUMENT ME! A String representation of the SDO Geometry.



visit
public void visit(GeometryFilter geomFilter)(Code)
Handles Geometry Filter encoding. Currently only supports the encoding of GEOMETRY_BBOX filters. If a GEOMETRY_BBOX filter is encounter it will be converted into an SDO_RELATE() function. If another filter is found, nothing will happen.
Parameters:
  geomFilter - The geometry filter to encode.
See Also:   org.geotools.filter.FilterVisitor.visit(org.geotools.filter.GeometryFilter)



visit
public void visit(LikeFilter filter)(Code)
Writes the SQL for the Like Filter. Assumes the current java implemented wildcards for the Like Filter: . for multi and .? for single. And replaces them with the SQL % and _, respectively. Currently does nothing, and should not be called, not included in the capabilities.
Parameters:
  filter - the Like Filter to be visited.



visit
public void visit(LiteralExpression literal)(Code)
Converts a literal expression into a valid SDO object. Only handles Literal Geometries, all other literals are passed up to the parent.
Parameters:
  literal - The Literal expression to encode.
See Also:   org.geotools.filter.FilterVisitor.visit(org.geotools.filter.LiteralExpression)



visit
public void visit(FidFilter filter)(Code)
DOCUMENT ME!
Parameters:
  filter -

visit
public void visit(AttributeExpression ae) throws RuntimeException(Code)
