Class GPUdbBase

java.lang.Object
com.gpudb.GPUdbBase
Direct Known Subclasses:
GPUdb
public abstract class GPUdbBase extends Object
Base class for the GPUdb API that provides general functionality not specific to any particular GPUdb request. This class is never instantiated directly; its functionality is accessed via instances of the GPUdb class. Usage patterns: 1. Unsecured setup 
         String url = "[http://your\\\_server\\\_ip\\\_or\\\_FQDN:9191](http://your\\_server\\_ip\\_or\\_FQDN:9191)";

         GPUdb.Options options = new GPUdb.Options();
         options.setUsername("user");
         options.setPassword("password");

         GPUdb gpudb = new GPUdb( url, options );

 
2\. Secured setup If options.setBypassSslCertCheck( true ) is set, then all forms of certificate checking whether self-signed or one issued by a known CA will be bypassed and an unsecured connection will be set up. A) This setup will enforce checking the truststore and the connection will fail if a mismatch is found 
         String url = "[https://your\\\_server\\\_ip\\\_or\\\_FQDN:8082/gpudb-0](https://your\\_server\\_ip\\_or\\_FQDN:8082/gpudb-0)";

         GPUdb.Options options = new GPUdb.Options();
         options.setUsername("user");
         options.setPassword("password");
         options.setTrustStoreFilePath("/path/to/truststore.jks");
         options.setTrustStorePassword("password\_for\_truststore");

         GPUdb gpudb = new GPUdb( url, options );
 
B) This setup will not enforce checking the truststore and the connection will succeed since the truststore will not be verified. if options.setBypassSslCertCheck(true) is there, then all other checks will be left out and the connection will succeed unless there are other errors like wrong credentials, non-responsive server etc. If a truststore (only for self-signed certificates) has to be used, one can set options.setTrustStoreFilePath("/path/to/truststore.jks") and options.setTrustStorePassword("password\_for\_truststore"), but in this case options.setBypassSslCertCheck( true ) cannot be used. 
         String url = "[https://your\\\_server\\\_ip\\\_or\\\_FQDN:8082/gpudb-0](https://your\\_server\\_ip\\_or\\_FQDN:8082/gpudb-0)";

         GPUdb.Options options = new GPUdb.Options();
         options.setUsername("user");
         options.setPassword("password");
         options.setBypassSslCertCheck( true );

         GPUdb gpudb = new GPUdb( url, options );
 
C) This setup will enforce checking any security related configurations and will proceed to set up a secured connection only if the server has SSL set up and a certificate from a well-known CA is available. In this case, the Java runtime makes sure that the server certificate is validated without the user having to specify anything. 
         String url = "[https://your\\\_server\\\_ip\\\_or\\\_FQDN:8082/gpudb-0](https://your\\_server\\_ip\\_or\\_FQDN:8082/gpudb-0)";

         GPUdb.Options options = new GPUdb.Options();
         options.setUsername("user");
         options.setPassword("password");

         GPUdb gpudb = new GPUdb( url, options );
