IConnectionProvider (IBM FHIR Server)

All Known Implementing Classes:

DerbyConnectionProvider, DerbyFhirDatabase, JdbcConnectionProvider, PoolConnectionProvider
```
public interface IConnectionProvider
```
Provides an abstract way to obtain a JDBC connection. Hides the implementation, making it easier to switch between in-memory instances of Derby used for unit-tests and connections to actual DB2 instances either in pure Java or JEE environments like Liberty Profile. One IConnectionProvider instance is used per data source. If you need to connect to more than one database, you'll need multiple providers. This is just simple wrapper stuff...allowing us to switch out underlying pool implementations should we want/need to. No support for distributed transactions or anything fancy like that.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`void`	`commitTransaction()`	Commit the current transaction if there's an actual connection associated with this thread (i.e.
`void`	`describe(String prefix, StringBuilder cfg, String key)`	Describe self, for writing configuration information to log file for test record purposes
`Connection`	`getConnection()`	Obtain a new connection to a data-source which this provider has been configured for.
`default int`	`getPoolSize()`	used to control threading size.
`IDatabaseTranslator`	`getTranslator()`	Get the translator associated with this connection provider.
`void`	`rollbackTransaction()`	Roll back the transaction for the connection associated with this thread, if one exists

- Method Detail
  - getConnection
```
Connection getConnection()
                  throws SQLException
```
    Obtain a new connection to a data-source which this provider has been configured for.
    
    Returns:
    
    Throws:
    
    SQLException
  - getTranslator
```
IDatabaseTranslator getTranslator()
```
    Get the translator associated with this connection provider. Supports interpretation of SQLExceptions and the ability to tweak SQL statements to handle differences between DB2 and Derby
    
    Returns:
  - commitTransaction
```
void commitTransaction()
                throws SQLException
```
    Commit the current transaction if there's an actual connection associated with this thread (i.e. if getConnection() has been called at least once), otherwise do nothing.
    
    Throws:
    
    SQLException
  - rollbackTransaction
```
void rollbackTransaction()
                  throws SQLException
```
    Roll back the transaction for the connection associated with this thread, if one exists
    
    Throws:
    
    SQLException
  - describe
```
void describe(String prefix,
              StringBuilder cfg,
              String key)
```
    Describe self, for writing configuration information to log file for test record purposes
    
    Parameters:
    
    cfg -
    
    key -
  - getPoolSize
```
default int getPoolSize()
```
    used to control threading size.
