public class OracleSdoGeometryDataType
extends AbstractDataType

This class implements DataType for Oracle SDO_GEOMETRY type used in Oracle Spatial. See the Oracle Spatial Developer's Guide for details on SDO_GEOMETRY. This class handles values similar to:

• SDO_GEOMETRY(NULL, NULL, NULL, NULL, NULL)
• NULL
• SDO_GEOMETRY(2001, 8307, SDO_POINT_TYPE(71.2988, 42.8052, NULL), NULL, NULL)
• SDO_GEOMETRY(3302, NULL, SDO_POINT_TYPE(96.8233, 32.5261, NULL), SDO_ELEM_INFO_ARRAY(1, 2, 1), SDO_ORDINATE_ARRAY(2, 2, 0, 2, 4, 2, 8, 4, 8, 12, 4, 12, 12, 10, NULL, 8, 10, 22, 5, 14, 27))

For more information on oracle spatial support go to http://tahiti.oracle.com and search for "spatial". The developers guide is available at http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28400/toc.htm

example table: CREATE TABLE cola_markets ( mkt_id NUMBER PRIMARY KEY, name VARCHAR2(32), shape SDO_GEOMETRY);

example insert: INSERT INTO cola_markets VALUES( 2, 'cola_b', SDO_GEOMETRY( 2003, -- two-dimensional polygon NULL, NULL, SDO_ELEM_INFO_ARRAY(1,1003,1), -- one polygon (exterior polygon ring) SDO_ORDINATE_ARRAY(5,1, 8,1, 8,6, 5,7, 5,1) ) );

This class uses the following objects which were rendered using oracle jpub and then slightly customized to work with dbunit:

• OracleSdoGeometry - corresponds to oracle SDO_GEOMETRY data type
• OracleSdoPointType - corresponds to oracle SDO_POINT_TYPE data type
• OracleSdoElemInfoArray - corresponds to oracle SDO_ELEM_INFO_ARRAY data type
• OracleSdoOridinateArray - corresponds to oracle SDO_ORDINATE_ARRAY data type

These classes were rendered via jpub (http://download.oracle.com/otn/utilities_drivers/jdbc/10201/jpub_102.zip) with the following command syntax: ./jpub -user=YOUR_USER_ID/YOUR_PASSWORD -url=YOUR_JDBC_URL -sql mdsys.sdo_geometry:OracleSdoGeometry, mdsys.sdo_point_type:OracleSdoPointType, mdsys.sdo_elem_info_array:OracleSdoElemInfoArray, mdsys.sdo_ordinate_array:OracleSdoOrdinateArray -dir=output_dir -methods=none -package=org.dbunit.ext.oracle -tostring=true The equals and hashCode methods were then added so that the objects could be compared in test cases. Note that I did have to bash the jpub startup script (change classpath) because it assumes oracle 10g database but I ran it with 11g. Theoretically, this process can be repeated for other custom oracle object data types.

Method Summary

Methods

Modifier and Type	Method and Description
int	compare(Object o1, Object o2) This method is copied from AbstractDataType and customized to call equals after the typeCast because OracleSdoGeometry objects are not Comparables but can test for equality (via equals method.) It is needed for test cases that check for equality between data in xml files and data read from the database.
Object	getSqlValue(int column, ResultSet resultSet) Returns the specified column value from the specified resultset object.
void	setSqlValue(Object value, int column, PreparedStatement statement) Set the specified value to the specified prepared statement object.
Object	typeCast(Object value) Returns the specified value typecasted to this DataType

Method Detail

typeCast

public Object typeCast(Object value)
                throws TypeCastException

Description copied from class: DataType

Returns the specified value typecasted to this DataType

Specified by:

typeCast in class DataType

Throws:

TypeCastException

getSqlValue

public Object getSqlValue(int column,
                 ResultSet resultSet)
                   throws SQLException,
                          TypeCastException

Description copied from class: DataType

Returns the specified column value from the specified resultset object.

Overrides:

getSqlValue in class AbstractDataType

Throws:

SQLException

TypeCastException

setSqlValue

public void setSqlValue(Object value,
               int column,
               PreparedStatement statement)
                 throws SQLException,
                        TypeCastException

Description copied from class: DataType

Set the specified value to the specified prepared statement object.

Overrides:

setSqlValue in class AbstractDataType

Throws:

SQLException

TypeCastException

compare

public int compare(Object o1,
          Object o2)
            throws TypeCastException

This method is copied from AbstractDataType and customized to call equals after the typeCast because OracleSdoGeometry objects are not Comparables but can test for equality (via equals method.) It is needed for test cases that check for equality between data in xml files and data read from the database.

Overrides:

compare in class AbstractDataType

Throws:

TypeCastException - if the arguments' types prevent them from being compared by this Comparator.
