| TKDBConnectionManager | | public class TKDBConnectionManager (Code) | | Manages database connections for an application context.
Each application context has its TKDBConnectionManager, which
provides its threads with database connections.
The manager contains all data needed to maintain connections to a database like
- database name,
- driver,
- username,
- password in
TKConnectData TKConnectData
Furthermore the manager contains information about data types supported by the database in
TKSQLTypeConverter TKSQLTypeConverter ,
a hash for the used query classes, a hash for the connections of threads,
a stack with currently unused connections,
and a mechanism for limiting simultaneously opened connections
TKLimiter TKLimiter .
|
| getConnection | | public Connection getConnection() throws SQLException(Code) | | Returns the connection of the current thread.
Connection the connection of the current thread. |
| getConnectionData | | public TKConnectData getConnectionData()(Code) | | Returns the connect data of the TKDBConnectionManager.
TKConnectData the connect data of this manager. |
| getTKDBConnection | | public TKDBConnection getTKDBConnection() throws SQLException(Code) | | Returns the TKDBConnection of the current thread.
If there is no connection available in
TKHashtable TKHashtable tkConnectionHash
and Stack tkConnectionStack is empty, a new connection will be opened.
If the limit, defined in the
TKLimiter TKLimiter limiter, of opened connections
will be exceeded, the current thread has to wait.
TKDBConnection TKDBConnection TKDBConnection of current thread.

| newQuery | | public TKQuery newQuery(Class inQueryClass) throws SQLException(Code) | | Instantiates an object of the specified class inQueryClass and adds it
to the queries maintained by this TKDBConnectionManager
within the
TKHashtable TKHashtable queryClasses.
Parameters:
inQueryClass - the class definition for the TKQuery to instantiate. the instantiated TKQuery |
| resetConnections | | public synchronized void resetConnections()(Code) | | |
| setConnectionData | | public synchronized void setConnectionData(TKConnectData data)(Code) | | Sets the connection data object of this manager.
Parameters:
data - the TKConnectData TKConnectData object to set. |
