Specified by:

deinstall in interface IConnectorManager

Throws:

ManifoldCFException

registerConnector

public void registerConnector(java.lang.String description,
                              java.lang.String className)
                       throws ManifoldCFException

className - is the class name.

Throws:

ManifoldCFException

unregisterConnector

public void unregisterConnector(java.lang.String className)
                         throws ManifoldCFException

Unregister a connector. The connector's deinstall method will also be called.

Specified by:

unregisterConnector in interface IConnectorManager

Parameters:

className - is the class of the connector to unregister.

Throws:

ManifoldCFException

removeConnector

public void removeConnector(java.lang.String className)
                     throws ManifoldCFException
