Example 37 with CommandException

the class FinalizeDatasetPublicationCommand method registerExternalIdentifier.

/**
 * Whether it's EZID or DataCite, if the registration is
 * refused because the identifier already exists, we'll generate another one
 * and try to register again... but only up to some
 * reasonably high number of times - so that we don't
 * go into an infinite loop here, if EZID is giving us
 * these duplicate messages in error.
 *
 * (and we do want the limit to be a "reasonably high" number!
 * true, if our identifiers are randomly generated strings,
 * then it is highly unlikely that we'll ever run into a
 * duplicate race condition repeatedly; but if they are sequential
 * numeric values, than it is entirely possible that a large
 * enough number of values will be legitimately registered
 * by another entity sharing the same authority...)
