Constructor Detail

ConnectionPoolManagerImpl

public ConnectionPoolManagerImpl(Map<String,String> moduleParameters,
                                 Server server,
                                 String role)
                          throws ModuleInitializationException

Constructs a new ConnectionPoolManagerImpl

Parameters:

moduleParameters - The name/value pair map of module parameters.

server - The server instance.

role - The module role name.

Throws:

ModuleInitializationException - If initialization values are invalid or initialization fails for some other reason.

Method Detail

initModule

public void initModule()
                throws ModuleInitializationException

Initializes the Module based on configuration parameters. The implementation of this method is dependent on the schema used to define the parameter names for the role of org.fcrepo.server.storage.ConnectionPoolManager.

Overrides:

initModule in class Module

Throws:

ModuleInitializationException - If initialization values are invalid or initialization fails for some other reason.

getPool

public ConnectionPool getPool(String poolName)
                       throws ConnectionPoolNotFoundException

Gets a named connection pool.

Specified by:

getPool in interface ConnectionPoolManager

Parameters:

poolName - The name of the connection pool.

Returns:

The named connection pool.

Throws:

ConnectionPoolNotFoundException - If the specified connection pool cannot be found.

getPool

public ConnectionPool getPool()
                       throws ConnectionPoolNotFoundException

Gets the default Connection Pool. This method overrides getPool(String poolName) .

Specified by:

getPool in interface ConnectionPoolManager

Returns:

The default connection pool.

Throws:

ConnectionPoolNotFoundException - If the default connection pool cannot be found.

shutdownModule

public void shutdownModule()
                    throws ModuleShutdownException

Closes all connection pools. This method overrides shutdownModule() .

Overrides:

shutdownModule in class Module

Throws:

ModuleShutdownException - If the close operation for the connection pool(s) fails.
