java.util.Vector	listConnections(StringTagger tagger)
java.util.Vector	listPools(StringTagger tagger)
java.lang.String	makeUrl() Routine build the url to give to the DriverManager to open the connection.
java.lang.String	makeUrl(java.lang.String dbm) Routine build the url to give to the DriverManager to open the connection.
java.lang.String	makeUrl(java.lang.String host, int port, java.lang.String dbm) Routine build the url to give to the DriverManager to open the connection.
java.lang.String	makeUrl(java.lang.String host, java.lang.String dbm) Routine build the url to give to the DriverManager to open the connection.
void	onload() prepares the module when loaded. Onload must be overridden to execute methods that need to be performed when the module is loaded but before any other modules are initailized. This method is called by Module.startModules(). You should not call onload() directly.

Method Detail

onload

public void onload()

Description copied from class: ProcessorModule

prepares the module when loaded. Onload must be overridden to execute methods that need to be performed when the module is loaded but before any other modules are initailized.
This method is called by Module.startModules(). You should not call onload() directly.

Overrides:

onload in class ProcessorModule

init

public void init()

Description copied from class: ProcessorModule

Initializes the module. Init must be overridden to read the environment variables it needs.
This method is called by Module.startModule(), which makes sure it is not called more than once. You should not call init() directly, call startModule() instead.

Overrides:

init in class ProcessorModule

reload

public void reload()

Reload the properties and driver

Overrides:

reload in class ProcessorModule

unload

public void unload()

Description copied from class: ProcessorModule

What should this do, when is this called? (MM)

Overrides:

unload in class ProcessorModule

shutdown

protected void shutdown()

Description copied from class: Module

Shuts down the module. This method is called by shutdownModules.

Overrides:

shutdown in class Module
