Description copied from class: ProcedureContainerResolver

Find all metadata defined by this command for it's children. This metadata should be collected in the childMetadata object. Typical uses of this are for stored queries that define parameter variables valid in subcommands. only used for inserts, updates, and deletes

Parameters:

command - The command to find metadata on

useMetadataCommands - True if resolver should use metadata commands to completely resolve

metadata - Metadata access
