FunctionInterface, VersionInfoInterface

public class InitITRegistryFC
extends Function

This Component initializes a connection to the IT registry and registers a Management Software System(MSS) in the IT registry database. It also returns the GUID with which MSS has got registered wrapped as a ConfigurationItemId, thus preventing the user to see its content, but allowing its usage by the other IT registry Components.

Method Detail

initialize

public void initialize(Object obj)
                throws Exception

Called once to initialize the Function Component.

Specified by:

initialize in interface FunctionInterface

Overrides:

initialize in class Function

Parameters:

obj - ignored.

Throws:

Exception - if an error occurs.

perform

public Object perform(Object obj)
               throws Exception

The FC receives the information about MSS data either from the configuration panel or from its Output Map and registers the MSS in the IT registry. Also it opens a IT registry book and fill the registration information in an IT registry Book and shares it statically.

Parameters:

obj - the work entry passed to the FC.

Returns:

an empty Entry object.

Throws:

Exception - if a problem occurs.

This method returns the JDBC Url used by the Connector.

Returns:

a JDBC Url.

getJdbcDriver

public String getJdbcDriver()

This method returns the JDBC Driver used by the Connector.

Returns:

a JDBC Driver.

getDbUsername

public String getDbUsername()

This method returns the username for connecting to the UT registry database used by the Connector.

Returns:

a database username.

querySchema

public Object querySchema(Object input)
                   throws Exception

This method displays the attributes belonging to the MSS class. For a source of this meta-data it uses either a local jar file or meta-data calls to an IT registry system (depending on its configuration).

Specified by:

querySchema in interface FunctionInterface

Overrides:

querySchema in class Function

Parameters:

input - entry object

Returns:
