Parameters:

threadContext - is the thread context.

database - is the database handle.

Throws:

ManifoldCFException

Method Detail

install

public void install()
             throws ManifoldCFException

Install or upgrade.

Specified by:

install in interface ITransformationConnectorManager

Throws:

ManifoldCFException

deinstall

public void deinstall()
               throws ManifoldCFException

Uninstall. This also unregisters all connectors.

Specified by:

deinstall in interface ITransformationConnectorManager

Throws:

ManifoldCFException

registerConnector

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

Register a new connector. The connector's install method will also be called.

Specified by:

registerConnector in interface ITransformationConnectorManager

Parameters:

description - is the description to use in the UI.

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 ITransformationConnectorManager

Parameters:

className - is the class name of the connector to unregister.

Throws:

ManifoldCFException

removeConnector

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

Remove a connector. Use this method when the connector doesn't seem to be in the classpath, so deregistration cannot occur.

Specified by:

removeConnector in interface ITransformationConnectorManager

Parameters:

className - is the connector class to remove.

Throws:

ManifoldCFException

getConnectors

public IResultSet getConnectors()
                         throws ManifoldCFException

Specified by:

getConnectors in interface ITransformationConnectorManager

Returns:

a resultset with the columns "description" and "classname". These will be ordered by description.

Throws:

ManifoldCFException

getDescription
