- =================================================================
- SAMPLE PROGRAMS
- FOR
- SPATIAL JAVA API VERSION 1.00,
- IBM INFORMIX SPATIAL DATABLADE MODULE, VERSION 8.20
-
- DATE: 06/15/2002
- =================================================================
- Several example Java programs are provided to demonstrate how to
- create and use geometry objects.
- The example programs have been tested with IBM Informix Dynamic
- Server 9.30, IBM Informix JDBC Driver 2.21.JC2, and Spatial DataBlade
- 8.11 and 8.20.
- GeometryToWKT
- -----------------
- Reads geometry objects from an IBM Informix spatial table and converts
- them into WKT (well-known text) strings. The program first creates a
- table, inserts geometry data, then queries the table. The output of
- this program shows the well-known text representation of sample
- geometries.
- GeometryToArray
- ----------------
- Creates new geometries using a geometry factory, then reads coordinate
- data out of the geometry objects. The program first creates several
- geometry objects and stores them in a Java vector, then uses two
- techniques to read coordinate data out of the geometry objects:
- - IfxGeometry.toCoordArray()
- - IfxGeometry.toPointArray()
- CoordRefCreate
- ---------------
- Creates new coordinate reference objects and inserts them into the
- SPATIAL_REFERENCES table.
- The program creates a new CoordRef object, then serializes it as a
- new SRS row into the SPATIAL_REFERENCES table. The output of this
- program shows the result of a query to retrieve the new spatial
- reference systems from the database.
- Setting your Classpath
- ------------------------
- When compiling or running any of these programs, set your CLASSPATH
- environment variable to include the Informix JDBC driver,
- the Spatial Java API jar file, and the directory where these programs
- are located.
- Compiling the programs
- -----------------------
- You can compile these programs by using the javac command. (Be sure
- that your CLASSPATH is set correctly). For example, to compile all
- the programs, go to the samples directory and enter the following command:
- javac *.java
- Running the programs
- ---------------------
- java <program> jdbc:informix-sqli://<host>:<port>/<database>:informixserver=<server>;user=<user>;password=<pass>
- where <program> = name of the class you want to execute
- <host> = hostname of the computer where IBM Informix Server is running
- <port> = port number that Informix server is listening on
- <database> = name of the database in which Spatial DataBlade is registered
- <server> = INFORMIXSERVER name
- <user> = your database user name
- <pass> = your database password
