use of com.mucommander.commons.file.filter.ChainedFileFilter in project mucommander by mucommander.

the class CommandManager method buildAssociations.

/**
 * Passes all known file associations to the specified builder.
 * <p>
 * This method guarantees that the builder's {@link AssociationBuilder#startBuilding() startBuilding()} and
 * {@link AssociationBuilder#endBuilding() endBuilding()} methods will both be called even if an error occurs.
 * If that happens however, it is entirely possible that not all associations will be passed to
 * the builder.
 * </p>
 * @param  builder          object that will receive association list building messages.
 * @throws CommandException if anything goes wrong.
