public interface PGConnection
This interface defines the public PostgreSQL extensions to java.sql.Connection. All Connections returned by the PostgreSQL driver implement PGConnection.
| Method Summary | |
|---|---|
void |
addDataType(java.lang.String type,
java.lang.Class klass)
This allows client code to add a handler for one of org.postgresql's more unique data types. |
void |
addDataType(java.lang.String type,
java.lang.String name)
Deprecated. As of 8.0, replaced by addDataType(String,Class). This deprecated method does not
work correctly for registering classes that cannot be directly loaded
by the JDBC driver's classloader. |
CopyManager |
getCopyAPI()
This returns the COPY API for the current connection. |
Fastpath |
getFastpathAPI()
This returns the Fastpath API for the current connection. |
LargeObjectManager |
getLargeObjectAPI()
This returns the LargeObject API for the current connection. |
PGNotification[] |
getNotifications()
This method returns any notifications that have been received since the last call to this method. |
int |
getPrepareThreshold()
Get the default server-side prepare reuse threshold for statements created from this connection. |
void |
setPrepareThreshold(int threshold)
Set the default statement reuse threshold before enabling server-side prepare. |

void addDataType(java.lang.String type,
java.lang.String name)
addDataType(String,Class). This deprecated method does not
work correctly for registering classes that cannot be directly loaded
by the JDBC driver's classloader.
addDataType(type, Class.forName(name)).
java.lang.RuntimeException - if the type cannot be registered (class not
found, etc).
void addDataType(java.lang.String type,
java.lang.Class klass)
throws java.sql.SQLException
NOTE: This is not part of JDBC, but an extension.
The best way to use this is as follows:
...
((org.postgresql.PGConnection)myconn).addDataType("mytype", my.class.name.class);
...
where myconn is an open Connection to org.postgresql.
The handling class must extend org.postgresql.util.PGobject
type - the PostgreSQL type to registerklass - the class implementing the Java representation of the type;
this class must implement PGobject).
java.sql.SQLException - if klass does not implement
PGobject).PGobjectvoid setPrepareThreshold(int threshold)
PGStatement.setPrepareThreshold(int) for
details.
