Method Detail

getFormalName

public String getFormalName()

Description copied from interface: NamedPlugin

Get the formal name of the plugin. This should be long enough to allow people who are not experts with the code to understand it, and will be written to the log to associate itself with the shorter name.

Specified by:

getFormalName in interface NamedPlugin

getName

public String getName()

Description copied from interface: NamedPlugin

Get the name of the plugin. This should be fairly short so that the logging messages aren't too massive.

Specified by:

getName in interface NamedPlugin

                        String[] namespaceMap,

                 throws org.globus.ogsa.GridServiceException,
