               ObjectConnection connection)
                 throws TranslatorException

Description copied from class: ExecutionFactory

Implement to provide metadata to the metadata for use by the engine. This is the primary method of creating metadata for dynamic VDBs.

Overrides:

getMetadata in class ExecutionFactory<javax.resource.cci.ConnectionFactory,ObjectConnection>

connection - may be null if the source is not required

Throws:

TranslatorException - to indicate a recoverable error, otherwise a RuntimeException
